Abstract
BACKGROUND Tobacco Smoking is one of the leading causes of preventable morbidity and mortality in the world. It is well documented that tobacco smoking is risk factor for many diseases like: cancers, chronic respiratory and cardiovascular diseases, and the effects of tobacco smoking on hematological indices gets a little attention: the data is mostly inconsistent regarding the differential of WBCs, a conflicting studies described the effect of smoking on hemoglobin descriptive parameters and a regular monitoring of platelets count in smokers was advised. OBJECTIVES The study aimed to evaluate the relationship between tobacco smoking and hematological parameters among Sudanese healthy Smokers at Bahri Town. METHODS This was a cross sectional study conducted during 2022 in Bahri town, Khartoum state. A total of 120 male subjects participated in this study. Of them, 60 healthy non-smokers participants (Control), and 60 age matched smokers who were smoking tobacco for a minimum of 1 year. Smokers group was divided into three major sub-groups with each group contains 20 subjects: Cigarettes smokers (CS), Water pipes (Shisha) smokers (WP) and both Cigarettes and water pipes (shisha) smokers (CSWP). Data was collected through questionnaire interviews and laboratory investigation. A sample of Five ml venous blood was taken for Complete blood count testing using Urite 3000 plus semi-automated hematology analyzer. Data were analyzed using SPSS version 25. Assocation between the variables were estimated and p value ≤ 0.05 was considered statistically significant. RESULTS Smokers had significantly higher RBCs count (p = 0.017), Hb level (p < 0.001), WBCs count (p = .017), Neutrophils (p < 0.001), MCH (p = 0.029), MCHC (p < 0.001), RDW (p < 0.001), and PDW (p < 0.001) compared to the non-smokers. In contrast, non-smokers had higher MPV (p < 0.001) and MCV (p < 0.001) levels than smokers. Between the non-smokers and different subtypes of the smokers (CS, WP & CSWP), there were significant differences between the subgroups for all hematological parameters except for PLTs and lymphocytes count. CS had lower levels of MCV (p < 0.001), MCHC (p < 0.001), HCT (p = 0.036), and RDW (p < 0.001) compared to the non-smokers, while both cigarette and shisha smokers had the higher levels of neutrophils count (p < 0.001) and PDW (p < 0.001) compared to the non-smokers. CONCLUSION Smoking affects hematological parameters; smokers had significantly higher RBCs count, Hb level, WBCs count, Neutrophils, MCH, MCHC, RDW and PDW compared to the non-smoker group. WP smoking caused higher levels of RBCs, Hb, neutrophils, MCH and MCHC. PDW was high in smokers' sub-groups compared to control group, while MPV was lower despite insignificant change In PLTs count.

Abstract
This study investigated the physiological and stress indices of scavenging chickens in LAFARGE and Dangote cement factories located at Ewekoro and Ibese, respectively and respective adjourning communities of Ogun State, Nigeria. One hundred adult scavenging chickens comprising of 25 from each location were used. The birds were caught at night on their perch and kept in furnished cages till the next morning. Data were collected on their rectal temperature, pulse rate, and respiratory rate . Also 5 mL blood was collected through the wing vein of each chicken. Highest (p < 0.05) pulse rate (215.64 beat/minute) and respiratory rate (19.90 breath/minute) were recorded among the chickens at LAFARGE area. Highest (p < 0.05) packed cell volume (28.06%), hemoglobin (4.01 g/dL), monocyte (4.28%) and glucose (256.53 g/dL) were recorded among ones at Ibese (Dangote). White blood cell (6488.89 × 103µL) was highest (p < 0.05) in chickens at Ewekoro (LAFARGE). The study concluded that cement factories infringe on health status of scavenging chickens in the domains. Effective environmental mitigation programme should be put in place for enhanced welfare of the birds.

Abstract
The goal of this study was to establish routine reference intervals (RI) for common laboratory tests for the European badger (Meles meles). Blood samples were collected from 13 female and 11 male adult European badgers in a wildlife rehabilitation facility and used for standard hematology and biochemistry analyses. The established 95% RI (2.5th-97.5th percentile) were determined by either parametric (normally distributed data) or robust (nonnormal data) statistical methods and showed a lower range of variability compared with those reported in previous literature. Sex did not affect any investigated parameters. As the first RI study on free-living European badgers in Italy, these reported hematology and serum chemistry RI provide a set of accurate and reliable laboratory parameters for this species.

Abstract
The present study comprehensively evaluates the postnatal growth, hematology, telomere length, and semen attributes of multiple clones and re-clone derived from superior buffalo breeding bulls. To the best of our knowledge, we successfully produced multiple clones and a re-clone of an earlier cloned buffalo bull from an embryo developed from an adult bull's skin-derived cell for the first time. The cloned bulls' growth, blood hematology, plasma biochemistry, and telomere length were all shown to be normal at various stages of development. The bulls were used for semen production after being screened for testicular growth and training. Semen characteristics such as volume, concentration, and initial motility of fresh sperm as well as motility and kinetics characteristics such as straightness (STR), average lateral head displacement (ALH), and beat cross frequency (BCF) of frozen-thawed sperms of the cloned bulls were found to be similar to those of non-cloned bulls, including the donor bulls. Additionally, it was found that cloned bulls' functional sperm attributes, including acrosome intactness, mitochondrial membrane potential, and superoxide anion status, were comparable to those of non-cloned bulls. These characteristics are necessary for sperm to pass through the female reproductive system, penetrate the oocyte, and efficiently fertilize. Finally, this study adds to our understanding of the postnatal development, hematology, telomere length, and sperm characteristics of superior buffalo breeding bulls that have been cloned and re-cloned. The findings provide the groundwork for improving cloning practices, refining reproductive procedures, and optimizing the use of cloned genetic material in animal breeding and conservation.

Abstract
INTRODUCTION Vaccine-induced immune thrombotic thrombocytopenia (VITT) is a life-threatening prothrombotic disorder first identified following the introduction of adenoviral vector vaccines for COVID-19. The condition is characterized by anti-PF4 antibodies and clinically presents with thrombocytopenia and thrombosis often in unusual anatomical sites. AREAS COVERED In this review, we discuss the clinical presentation, diagnostic testing, and treatment of VITT. We also review VITT-like syndromes that have been described in patients without previous vaccination. We propose a conceptual framework for the mechanism of anti-PF4 diseases that includes sufficiently high levels of PF4, the presence of a Polyanion that can form immune complexes with PF4, a Pro-inflammatory milieu, and an immunological Predisposition - the 4Ps. EXPERT OPINION Significant progress has been made in understanding the characteristics of the VITT antibody and in testing methods that can confirm that diagnosis. Future work should be directed at understanding long-term outcomes, mechanisms of thrombosis, and individual risk factors for this rare but dangerous immune-thrombotic disease.

Abstract
A study was designed to evaluate the effect of Moringa oleifera, Phyllanthus amarus and Viscum album leaf meal as herbal inclusions to alleviate the detrimental outcomes of heat stress in weaned female rabbits. Forty (40) weaned rabbit does (527.99 ± 10.35 g; 28 days old) were randomly allotted to four dietary groups consisting of Diet 1(control diet; without leaf meal), Diets 2 (supplemented with 10% V. album); 3 (supplemented with 10% M. oleifera) and 4 (supplemented with 10% P. amarus) in an 84 days trial at the peak of heat stress in Southwest Nigeria. At the end of the trial, blood samples were collected to assess physiological responses and oxidative status of the rabbit does. The results obtained revealed that rabbit does were exposed to heat stress; rabbit does fed control diet had higher leucocyte and neutrophil/lymphocyte ratio compared to rabbit does fed on herbal inclusions. The herbal inclusions enhanced oxidative stability of rabbit does by lowering lipid peroxidation and enhancing antioxidant activities during heat stress conditions. Rabbit does fed control-based diet had significantly higher heat shock protein 70, leptin and adiponectin compared to rabbit does on M. oleifera, P. amarus and V. album supplemented diets. The herbal inclusions tend to suppress proinflammatory cytokines in rabbit does during heat stress condition. In conclusion, the herbal inclusions suppress inflammation, adipokines and promotes oxidative stability of rabbit does exposed to heat stress conditions.

Abstract
The American black bear (Ursus americanus) is an opportunistic and adaptable species with high rehabilitation success rates. Injured, ill, and orphaned bears across the southeastern United States are examined and treated at the University of Tennessee College of Veterinary Medicine followed by rehabilitation at Appalachian Bear Rescue (ABR). Hematology and biochemistry reference ranges exist for healthy adult black bears; however, most bears presenting to ABR are young and of variable health status. Thus, further investigation into the difference of blood values at varying ages and presentations is warranted. ABR records from 1996 to 2022 included 106 bears with completed hematology and plasma biochemistry panels (22 paired samples at intake and release, 84 at intake only). Intake-only samples consisted of 12 neonates (<3 mon old), 64 cubs (3-12 mon), and 30 yearlings (1-2 yr). Bears presented as orphaned neonates (22%), orphaned cubs (45%), malnourished yearlings (24%), and injured/ill (9%) during fall (16%), winter (13%), spring (32%), and summer (39%). Changes in hematology and plasma biochemistry results between intake and release included an increase in hematocrit and glucose. Injured/ill bears presented with higher total leukocyte count (WBC), absolute neutrophils (ABS segs), alanine aminotransferase (ALT), aspartate aminotransferase (AST), and creatine kinase (P < 0.05). Positive correlation between ALT, AST, proteins, and blood urea nitrogen and negative correlation between absolute lymphocytes and alkaline phosphatase were noted with age. Both WBC and ABS segs were lower during winter (P < 0.05). Understanding what factors affect juvenile black bear blood values improves clinical expectations and evaluation upon intake, clinical evaluation, and treatment.

Abstract
BACKGROUND Pediatric Hematology Oncology patients undergo frequent needlestick procedures, often leading to negative outcomes including pain and anxiety. Animal-assisted therapy has been shown to minimize pediatric patient distress; however, its utilization by a Certified Child Life Specialist (CCLS) to reduce patient distress has not been widely studied. METHODS Pediatric patients receiving needlesticks in the Hematology Oncology Clinic were enrolled between March 2018 and May 2021. Patients who had scheduled visits when the facility dog was present were assigned to the intervention group. Patients were assigned to the control group if the facility dog was not present. The primary objective was to use the Children's Anxiety and Pain Scale to determine whether the CCLS and facility dog dyad minimized patient pain and anxiety during procedures. RESULTS A total of 285 patients, 5 to 17 years of age, were enrolled. One hundred forty-three patients were assigned the intervention and received procedural support from the CCLS and facility dog; 142 patients were assigned the control group and received support from the CCLS only. Patient-reported pain scores were significantly lower among patients who received the intervention ( P =0.033). CONCLUSIONS Utilization of a CCLS and facility dog dyad during painful needlestick procedures decreases patient-reported pain compared with utilization of CCLS support alone.

Abstract
INTRODUCTION The objective of this project was to assess the percentage of interoperability compliance within our pediatric hematology/oncology patient care areas for intravenous chemotherapy medications before and after the implementation of circle priming. METHODS We conducted a retrospective quality improvement project at an inpatient pediatric hematology/oncology floor and outpatient pediatric infusion center before and after implementation of circle priming. RESULTS There was a statistically significant increase in percent interoperability compliance for the inpatient pediatric hematology/oncology floor from 4.1% prior to implementation of circle priming to 35.6% after (odds ratio 13.1 (95% CI, 3.96-43.1), p < 0.001), as well as for the outpatient pediatric infusion center from 18.5% to 47.3%, respectively (odds ratio 3.9 (95% CI, 2.7-5.9), p < 0.001). CONCLUSION Implementation of circle priming has significantly increased the percentage of interoperability compliance for intravenous chemotherapy medications in our pediatric hematology/oncology patient care areas.

Abstract
PURPOSE To understand the spectrum and volume of classical hematology (CH) referrals to hematology clinics at a National Cancer Institute (NCI)-designated cancer center (CC) to plan for the delivery of effective and equitable care for this population. METHODS One referral office at the Academic CC located in Bexar County, TX, handles all adult hematology referrals. From October 1, 2021, to September 30, 2022, all nonmalignant hematology (MH) referrals were triaged daily to define the category of CH problem. Declined referrals (confirmed at triage that no CH problem was evident) are included as part of this analysis. Electronic consultation (opinion rendered without patient seen) at our CC is available and is not part of this analysis. RESULTS One thousand nine hundred forty-five CH referrals were received in the 12-month period. Seventy-six referrals (3.9%) were declined. During the study period, there were 2,289 medical oncology referrals and 779 referrals for MH. CH referrals therefore comprise 39% of all hematology-oncology referrals and 71% of all hematology referrals at the CC. Anemia and thrombotic disorders were the most common categories of the accepted CH referrals at 487 (26%) and 393 (21%), respectively. Video visits were used for 447 of all CH referrals (23%), and the rest were in person. CONCLUSION Nearly 40% of all referrals to hematology and medical oncology at our NCI-designated CC are for CH. Effective management of the CH population of patients will allow ideal care for CH problems and also allow cancer-focused care to improve.

Abstract
BACKGROUND AND OBJECTIVES Outcomes of rare paediatric teratomas have not previously been reported nor treatment regimens standardised in low- and middle-income settings. We sought to evaluate treatment outcomes of children and adolescents with histologically confirmed extracranial germ cell tumours, both mature teratomas (MT) and immature teratomas (IT) in preparation for the development of the South African national treatment guideline. METHODS Retrospective data by folder review were collated from nine South African paediatric oncology units. Kaplan-Meier analysis with Cox regression was performed to determine 5-year overall survival (OS) and prognostic factors. RESULTS From January 1990 to December 2015, 60 patients were diagnosed with MTs; 14 males (median age 2 months; interquartile range [IQR]: 0-8.75 months) and 46 females (median age 9 months; IQR: 0-88.5 months). Forty patients were diagnosed with ITs; 10 males (median age less than 1 month; IQR: 0-1.75 months) and 30 females (median age 4.5 months; IQR: 1-162 months). There were high rates of upfront surgical resections in patients with MTs (58/60; 96.6%) and ITs (36/40; 90%), and similarly satisfactory rates of complete resection in patients with both MTs (55/60; 91.7%) and ITs (32/40; 80%). The 5-year OS for the whole group was 85.4%, significantly influenced by stage: Stage I (96.9%), Stage II (100%), Stage III (38.9%) (p < .001 [MT]; p = .013 [IT]). The event-free survival (EFS) ratio for the whole cohort was 78.7%. CONCLUSIONS Five-year OS for those with low-stage disease was excellent, but was poorer for patients with advanced disease. The implementation of a national treatment guideline will facilitate the standardising of surgical approaches, indications for chemotherapy and specifications for follow-up to improve survival and to collect more robust late effects data.

Abstract
In horses and donkeys, age-related changes in hematological and biochemical parameters preclude the use of normal values of adults in the evaluation of foals. This study aimed to obtain data on hematological and biochemical parameters of mule foals from birth up to the second month of life and to assess age-related changes in order to determine if dedicated reference ranges are required in younger animals. Blood samples from seven healthy mule foals were obtained at birth before colostrum consumption, 24 h, 48 h of life, and then weekly until the second month of life. Results were expressed as mean and standard deviation or median, minimum, and maximum values if showing non-gaussian distribution. Kruskal-Walls and Dunn tests were used to verify the differences among sampling times. Significance was set at P < 0.05. Red blood cell count, packed cell volume and hemoglobin decreased from 24 h to one week of age. Mean corpuscular volume and mean corpuscular hemoglobin decreased over the first month. White blood cells increased from birth to seven days of life. Aspartate amino transferase increased while alkaline phosphatase decreased in the first week of life. Urea, creatinine, and lactate decreased, while glucose concentrations increased at 24 h. Ionized calcium and magnesium and total sodium and potassium showed no changes. In mule foals, several laboratory parameters may be the same or intermediate, lower or higher than in equine or donkey foals, but also compared to all other adult species. The preliminary results suggest that for mule foals, age influences hematological and biochemical parameters.

Abstract
BACKGROUND Diagnostic accuracy of galactomannan measurements is highly variable depending on the study population, diagnostic procedures, and treatment procedures. We aimed to evaluate the effect of posaconazole prophylaxis and empiric antifungal treatment upon diagnostic accuracy of GM measurements in bronchoalveolar lavage (BAL), bronchial lavage (BL), and serum in hematological malignancy population. METHODS Patients hospitalized in a single tertiary care center with hematologic malignancies undergoing fiberoptic bronchoscopy (FOB) with a preliminary diagnosis of IPA were retrospectively included. RESULTS In all the study population (n = 327), AUC for BAL, BL, and serum GM were as follows: 0.731 [0.666-0.790], 0.869 [0.816-0.912], and 0.610 [0.540-0.676] with BL samples having the best diagnostic value. GM measurements in patients under posaconazole prophylaxis (n = 114) showed similar diagnostic performance. While specificity was similar between patients with and without posaconazole prophylaxis, sensitivity of GM measurements was lower in patients with prophylaxis. Analyses with patient classified according to antifungal treatment at the time of FOB procedure (n = 166) showed a decreased diagnostic accuracy in serum GM and BAL GM measurements related with the duration of treatment. However, BAL, BL, and serum GM measurements presented similar sensitivity and specificity in higher cut-off values in longer durations of antifungal treatment. CONCLUSION Our study shows that posaconazole prophylaxis and active short-term (3 days) antifungal treatment do not significantly affect overall diagnostic performance of GM measurements in bronchoalveolar lavage and bronchial lavage samples. However, using different cut-off values for patients receiving active treatment might be suggested to increase sensitivity.

Abstract
BACKGROUND After-hour calls can be resource intensive and remain a significant challenge to medical practices, though they have historically been poorly or non-reimbursable services. This study reviews after-hour calls from hematology/oncology patients at a cancer center to characterize after-hour care needs, identify care gaps, and look for opportunities to improve outpatient healthcare delivery. METHODS This descriptive, retrospective Institutional Review Board-approved study analyzed patient calls between June 2015 to February 2021 in an academic hematology/oncology practice. Data from 500 calls were reviewed and cataloged into a database including patient demographics, clinical history, and information surrounding the call (e.g., primary reason for the call, outcome of the call). Calls were also categorized as being urgent or not from a patient or provider's perspective. RESULTS Among 500 calls, representing 398 unique patients, the average patient was 62 years old and 52% of calls were from females. Most calls were made to report symptoms (65%), followed by calls to follow-up on labs, tests, or imaging (13%), and clarifying treatment plans (10%). Oncology patients represented 67% of calls and hematology (malignant and benign) patients represented 33%. More specifically, patients with gastrointestinal cancer (25%), hematologic malignancies (24%), and thoracic cancer (13%) represented the diagnoses with the highest call volume. CONCLUSIONS This study explores the complexity and variety of after-hour cancer patient calls. By systematically exploring patient calls, this data can provide insight into patients' needs outside of regular clinic times and help practices develop strategies to anticipate these needs, reduce after-hour call burden, and improve overall quality of care.

Arch Pathol Lab Med 2024; 148:61-67.

Abstract
CONTEXT.— Platelet (PLT) counting with impedance (PLT-I) is widely used but has low specificity. PLT counting with fluorescence (PLT-F), tested by the Sysmex XN series with high specificity, can be a complementary method to PLT-I. OBJECTIVE.— To identify red blood cell (RBC)- and PLT-related parameters as potential influencing factors for PLT-I and establish PLT reflex test rules with PLT-F. DESIGN.— We prospectively tested both PLT-I and PLT-F in all 3480 samples. In a development data set of 3000 samples, differences between the reflex and nonreflex groups were compared and influencing factors for PLT-I were identified by logistic regression. The area under the receiver operating characteristic (ROC) curve and cutoff values were obtained by ROC curve analysis. Validation was conducted in the remaining 480 samples (validation data set). RESULTS.— PLT-F showed comparable results with immunoplatelet counting. In logistic regression, increased micro-RBC absolute count (micro-RBC#), fragmented RBC absolute count (FRC#), PLT distribution width (PDW), mean PLT volume (MPV), PLT-large cell ratio (P-LCR), and immature PLT fraction absolute count (IPF#) were influencing factors for PLT-I. In ROC curve analysis, the cutoff values of micro-RBC#, FRC#, PDW, MPV, and P-LCR were 0.64 × 106/μL, 0.082 × 106/μL, 15.40 fL, 11.15 fL, and 33.95%, respectively. The areas under the ROC curve of micro-RBC# and FRC# were 0.77 and 0.79, respectively. CONCLUSIONS.— Micro-RBC#, FRC#, PDW, MPV, P-LCR, and IPF# were factors affecting PLT-I. Among them, micro-RBC# and FRC# were the most impactful factors. From our study results, micro-RBC#, FRC#, MPV, PDW, and P-LCR can be used to establish reflex test rules for PLT counting in clinical work.

Abstract
The use of triggers for the active search and detection of adverse drug events (ADEs) has been gaining ground within pharmacovigilance services. Thus, the main objective of the study was to propose a new list of triggers to be used in a center specialized in hematology in Rio de Janeiro, Brazil. The update of the list of triggers consisted of revising the current list, with the exclusion and inclusion of new triggers. To verify the performance of the new list of triggers, a cross-sectional study was conducted in which the new triggers were used to investigate the occurrence of ADEs in patients attended in the emergency unit or hospitalized from January to March 2022. For each suspected ADEs, the patient's profile and adverse drug reactions (ADRs) were characterized regarding causality and severity. The performance of the triggers and their ability to capture ADEs were estimated using the following indicators: frequency of the trigger per 100 medical records, frequency of ADEs per 100 records, and positive predictive value (PPV). To evaluate the overall performance of the proposed new list, the PPV was estimated. A total of 374 prescriptions for triggers were identified in 186 medical records. The most efficient in the detection of possible ADEs were: lidocaine, loperamide, bisacodyl, filgrastim and glycerin clyster. The overall PPV of the new suggested list was 48% versus 10% of the previous list. This study demonstrated the importance of an updated list of triggers for the monitoring of ADEs and improvement of the care provided.

Abstract
BACKGROUND A recent randomised trial demonstrated [18F]fluorodeoxyglucose positron-emission tomography in combination with low-dose CT (FDG-PET/CT), compared to standard of care computed tomography (CT) imaging, positively impacted antimicrobial management and outcomes of acute leukaemia and haematopoietic stem cell transplant recipients with persistent and recurrent neutropenic fever. We conducted an economic evaluation from a healthcare perspective alongside the clinical trial. METHODS Unit costs in Australian dollars were applied to all resources used (antimicrobials, diagnostic tests, ICU and hospital bed days). Effectiveness was measured as number of patients with antimicrobial rationalisation, 6-month mortality and quality-adjusted life years (QALYs) derived from patient-reported trial-based health-related quality-of-life. Generalised linear models were used to analyse costs and outcomes. Incremental cost-effectiveness ratios (ICERs) for all outcomes and net monetary benefit (NMB) for QALYs were calculated. We performed bootstrapping with 1000 replications using the recycled predictions method. RESULTS The adjusted healthcare costs were lower for FDG-PET/CT (mean $49,563; 95%CI 36,867, 65,133) compared to CT (mean $57,574; 95% CI 44,837, 73,347). The difference in QALYs between the two groups was small (0.001; 95% CI -0.001, 0.004). When simulated 1000 times, FDG-PET/CT was the dominant strategy as it was cheaper with better outcomes than the standard CT group in 74% of simulations. The estimated NMBs at willingness-to-pay thresholds of $50,000 and $100,000 per QALY were positive, thus FDG-PET/CT remained cost-effective at these thresholds. CONCLUSIONS FDG-PET/CT is cost effective when compared to CT for investigation of persistent/recurrent neutropenic fever in high-risk patients, providing further support for incorporation of FDG-PET/CT into clinical guidelines and funding. TRIAL REGISTRATION This trial is registered with ClinicalTrials.gov, NCT03429387.

Abstract
INTRODUCTION We sought to quantify percentages of microcytes and macrocytes in archived automated hematology analyzer (AHA) red blood cell (RBC) volume histogram images. METHODS In preliminary studies, we demonstrated that an on-line application of Gauss' area formula (SketchAndCalc™) measured percentage areas of 20 segments under a computer-generated normal distribution curve (-3.0 standard deviations [SD] to +3.0 SD) with accuracy and precision (Pearson's correlation of measured areas with corresponding theoretical areas r [20] = 0.9962 [p < 0.0001]). Thus, we used SketchAndCalc™ to quantify percentages of microcytes (50-80 fL) and macrocytes (110-200 fL) in archived AHA histogram images in women with previously untreated iron-deficiency anemia (IDA) and previously untreated hemochromatosis. RESULTS Median microcyte percentages in 13 women with IDA and 13 women with hemochromatosis were 63.6% (range 13.5-76.8) and 6.7% (range 3.4-24.8), respectively (p < 0.0001). Mean macrocyte percentages in women with IDA and hemochromatosis were 8.8% ± 6.1 SD and 33.8% ± 11.7 SD, respectively (p < 0.0001). Spearman's correlations of microcyte percentages with macrocyte percentages, mean corpuscular volume, and mean corpuscular hemoglobin in 26 women were rs [26] = -0.9485, rs [26] = -0.9641, and rs [26] = -0.9036, respectively (each p < 0.0001). CONCLUSIONS This method of quantifying microcyte and macrocyte percentages could enable other studies of RBC volume subpopulations in archived AHA histogram images.
