Abstract
Proper blood collection and timely analysis are vital steps for reliable results. This study aims to compare potassium(K), calcium(Ca), and phosphorus(P) concentrations in serum separator tube (SST), lithium heparin tube without gel (LiH), and lithium heparin tube with a barrier (Barricor)tubes in essential thrombocytosis(ET) patients. Additionally, we assessed short-term stability of these analytes at room temperature. K, Ca and P concentrations of blood taken from 40 ET patients into SST, LiH and Barricor tubes were measured at 0, 2, 4 and 8 h. We calculated the percentage difference and defined the maximum permissible difference (MPD) using the Biological Variation Database. Intertube comparisons were conducted using Passing-Bablok regression and Bland-Altman analysis. Comparing SST to LiH, the percentage difference values for all tests exceeded the MPD. When comparing Barricor to LiH, K and Ca tests were above MPD, except for P. At the 8th hour, LiH showed clinically significant changes in all three electrolytes. Barricor exhibited stability for K, Ca, and P for up to 8 h, with only Ca levels borderline higher than the MPD. Our study reveals clinically significant alterations in K, Ca, and P concentrations in SST compared to LiH tubes, and in K and Ca concentrations in Barricor compared to LiH tubes. While K, Ca and P concentrations were stable for up to 4 h at room temperature in all tube types tested, significant changes were observed in all electrolytes at 8 h in the LiH tube.

Abstract
PURPOSE Obesity, a low-grade systemic inflammatory disease, causes inflammation in metabolic tissues. Galectin-3(Gal-3) is one of the lectin molecules involved in inflammatory processes. We evaluated the possible relationship between Gal-3 level and the metabolic inflammatory process before and after obesity surgery. METHODS One hundred participants were included in the study and classified as normal weight, overweight, Class I, II, and III obese. Class III obese group underwent bariatric surgery and evaluated in the 3rd and 6th months after surgery. Glucose, insulin, glycated hemoglobin A1c (HbA1c), homeostatic model assessment of insulin resistance (HOMA-IR), high sensitivity C-reactive protein (hsCRP), Gal-3, interleukin (IL)-6, IL-10, adiponectin, and leptin levels were determined. RESULTS Gal-3 levels were higher in Class III obese compared to the normal weight group. Postoperative leptin and hsCRP levels were decreased significantly, but the decrease in IL-6 and Gal-3 levels were not significant. Postoperative increased adiponectin and IL-10 levels were significant. Gal-3 was found significantly higher in insulin resistant group. The correlation between Gal-3 with BMI, adiponectin, leptin, hsCRP levels, and HOMA-IR was found weak. CONCLUSION These findings might support the fact that Gal-3 is one of the molecules involved in the linkage between insulin resistance and meta-inflammation in morbid obese.

Abstract
Abstract
Objective
The aim of this study is to investigate the diagnostic accuracy of complete blood count (CBC), C-reactive protein (CRP), and procalcitonin (PCT) levels, which can be used as a cultural alternative for the diagnosis of infection faster.
Methods
The patients were divided into two groups as bacteremia (n = 220) and nonbacteremia group (n = 812). The bacteremia group was divided into two subgroups as Gram-positive bacteria (n = 167) and Gram-negative bacteria (n = 53).
Results
PCT, CRP, red blood cell distribution width (RDW), platelet distribution width (PDW), neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR), and mean platelet volume (MPV) levels were significantly higher in patients with positive blood culture than non-patients. The serum PCT levels were 3.80 (0.83–37.68) and 0.43 (0.16–2.61) ng/mL, respectively (p < 0.001) in the patients with Gram-negative and Gram-positive bacterium. PCT at a cut-off value of 0.45 ng/mL for Gram-negative bacterium; sensitivity of 90% and specificity of 64%.
Conclusions
It is important that RDW, PDW, NLR, PLR, MPV values can be measured quickly, easily and cheaply by automatic hematological analysis. However, among the markers tested, PCT has the best diagnostic performance for Gram-negative bacteremia.

Abstract
BACKGROUND The most common sources of error in the preanalytical phase are considered to be at the stage of patient preparation and sample collection. In order to reduce the preanalytical errors, we aimed to determine the level of phlebotomists knowledge about the preanalytic phase before and after planned trainings in the study. METHODS Training about preanalytical processes was given to the 454 health professionals and the majority of them were employed as nurse. Questionnaires before and after training were conducted. In order to assess the effect of the training into the process, preanalytical error rates were calculated before and after training. RESULTS The total correct answer rates of vocational school of health diplomaed were statistically lower than the total correct answer rates of other. It was observed significantly increase in the rate of correct answers to questionnaire and significantly decrease in preanalytical error rates after training. CONCLUSIONS The results of the survey showed that the attitudes of the phlebotomists were diverse in the preanalytical processes according to the levels of education and their practices. By providing training to all staff on a regular basis, their information about preanalytical phase could be updated and hence, it may possible to significantly reduce the preanalytical errors in health practice and nursing science.

Abstract
INTRODUCTION Although serum-providing blood tubes with a barrier are still widely used due to their significant advantages, the use of blood tubes with a barrier to provide plasma is becoming widespread. We compared 22 analytes in a BD Vacutainer® Barricor LH Plasma tube for local clinical validation of this new lithium heparin tube with a barrier. MATERIALS AND METHODS Samples from 44 volunteers were collected in different tubes (Becton Dickinson and Company): Z tube without additive (reference), clot-activator tube with gel (SST), lithium heparin tube without gel (LiH), and lithium heparin tube with barrier (Barricor). Analyte concentrations in different tubes were compared with the reference tube. All tubes were also evaluated according to additional testing (different centrifugation durations, blood-sampling techniques and individual differences). RESULTS Aspartate aminotransferase (AST), glucose (Glc), potassium (K), lactate dehydrogenase (LD), sodium (Na), and total protein (TP) had a significant bias in Barricor (9.19%, - 3.24%, - 4.88%, 21.60%, - 0.40%, 5.03%, respectively) relative to the reference tube. There was no statistical difference between different centrifugation durations and individual differences for AST, K and LD in LiH and/or Barricor (P > 0.05). There was a significant bias for LD between LiH and Barricor in terms of blood-sampling techniques (21.2% and 12.4%, respectively). CONCLUSIONS Recently, the use of plasma has become prominent due to some of its advantages. In this study, plasma AST, K, LD, Glc and TP levels in Barricor were clinically different in comparison to serum. The results of additional tests showed that higher levels of LD in Barricor did not result from haemolysis, and they might be related to other factors including number of platelets, cellular fragility, or functional environment.
