Abstract
INTRODUCTION The direct antiglobulin test (DAT) identifies immunoglobulin IgG and/or complement onthe red blood cell surface, allowing discrimination between immune and non-immunehemolysis. When the DAT is negative but there is clinical suspicion for immunehemolysis, an enhanced DAT can be sent to an immunohematology referencelaboratory (IRL). METHODOLOGY This retrospective study assessed the volume of enhanced DATs at a large tertiarycare center and evaluated their impact on patient care. Enhanced DATs were sent on21 adult patients (January 2019 - January 2021) at the University of Pittsburgh MedicalCenter and Allegheny Health Network. Laboratory and clinical data were collected andanalyzed. RESULTS Four out of 21 patients had positive tests (DAT and other serologic tests) at the localIRL. Enhanced DAT testing yielded positive results in an additional 5 patients butnegative or invalid results for 2 patients. High-dose steroid therapy was started in 12patients prior to receipt of enhanced DAT results. Enhanced DAT testing was sent amedian of 5 days after initiation of steroid therapy. For the patients trialed on steroids,the enhanced DAT results impacted medical decision-making in only 3 patients, and inonly one of those patients was the enhanced DAT positive despite a negative DAT at alocal IRL. In the non-steroid treated patients, enhanced DAT results did not contributeto clinical decision-making. CONCLUSION Enhanced DATs generally did not impact medical decision-making in adults withhemolytic anemia.

Abstract
In this unprecedented crisis of severe acute respiratory syndrome coronavirus 2 and its associated coronavirus disease 2019 (COVID-19), polymerase chain reaction and then serological testing platforms have been massively developed to face the important screening demand. Polymerase chain reaction and serological testing platforms are not the only actors impacted by the crisis, transfusion services are facing important difficulties. A positive direct antiglobulin test is frequently observed for patients encountering COVID-19. Patients with severe symptoms may develop anaemia and become good candidates for blood transfusions. The interpretation of a positive direct antiglobulin test for patients recently transfused and suffering from COVID-19 is complex. The differentiation between COVID-19 induced antibodies and possible associated transfusion alloantibodies is therefore crucial. In this context, the elution technique incorporated in an appropriate decision-making process plays its full role. This intricate topic is presented through a case report followed by literature review and finally decision-making process for COVID-19 patients necessitating red blood cells administration.

Vet J 2021; 272:105663. [PMID: 33941337 DOI: 10.1016/j.tvjl.2021.105663] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/15/2020] [Revised: 03/18/2021] [Accepted: 03/23/2021] [Indexed: 10/21/2022]
Abstract
Major crossmatch testing can help identify immunologic incompatibilities between blood donors and recipients; however, there are limited studies describing the accuracy of point-of-care crossmatch tests. The first aim of this study was to determine if a gel-based, point-of-care major crossmatch method (GEL-CM), without antiglobulin-enhancement, could accurately detect compatible and incompatible donor-recipient pairings, using an antiglobulin-enhanced laboratory-based major crossmatch method (LAB-CM) as the reference standard. The second aim was to describe the incidence of, and risk factors for, major crossmatch incompatibility in cats. Nineteen previously-transfused cats and 32 transfusion-naïve cats, representing 132 unique donor-recipient pairings, were included in this study. Both LAB-CM and GEL-CM tests were performed for most parings. There was poor agreement between the LAB-CM and GEL-CM results (kappa = 0.111; 95% confidence interval [CI], -0.093 to 0.314). Transfusion-naïve cats had incompatibility rates of 3% and 6% using LAB-CM and GEL-CM, respectively; previously-transfused cats had incompatibility rates of 32% and 26% using LAB-CM and GEL-CM, respectively. History of previous transfusion was the only identified cat risk factor for an incompatible LAB-CM (odds ratio [OR], 31.0; 95% CI, 3.77-254.98; P = 0.0019) and GEL-CM (OR, 5.7; 95% CI, 1.72-19.20; P = 0.0054). Further studies are needed to determine if GEL-CM can detect clinically-relevant immunologic incompatibilities that would result in transfusion reactions. Major crossmatch testing is of greater importance in cats that have previously received a transfusion.

Abstract
OBJECTIVE To systematically review available evidence to develop guidelines for the prevention of transfusion reactions and monitoring of transfusion administration in dogs and cats. DESIGN Evidence evaluation of the literature (identified through Medline searches through Pubmed and Google Scholar searches) was carried out for identified transfusion reaction types in dogs and cats. Evidence was evaluated using PICO (Population, Intervention, Comparison, Outcome) questions generated for each reaction type. Evidence was categorized by level of evidence (LOE) and quality (Good, Fair, or Poor). Guidelines for prevention and monitoring were generated based on the synthesis of the evidence. Consensus on the final recommendations and a proposed transfusion administration monitoring form was achieved through Delphi-style surveys. Draft recommendations and the monitoring form were made available through veterinary specialty listservs and comments were incorporated. RESULTS Twenty-nine guidelines and a transfusion administration monitoring form were formulated from the evidence review with a high degree of consensus CONCLUSIONS: This systematic evidence evaluation process yielded recommended prevention and monitoring guidelines and a proposed transfusion administration form. However, significant knowledge gaps were identified, demonstrating the need for additional research in veterinary transfusion medicine.

Detection of naturally occurring alloantibody by an in-clinic antiglobulin-enhanced and standard crossmatch gel column test in non-transfused domestic shorthair cats. J Vet Intern Med 2018; 33:588-595.

Abstract
Background Blood typing for the A and B antigens is essential and crossmatching testing is generally recommended before transfusing blood to cats. Objective To evaluate 2 crossmatch (XM) tests. Animals Forty‐nine healthy domestic shorthair cats that had not received a blood transfusion. Methods Prospective study. Blood samples were typed for AB using immunochromatographic and flow cytometric techniques. A gel column (GC) and a feline antiglobulin‐enhanced gel column (AGC) XM tests were used for crossmatching. Results The population included 34 type A, 13 B, and 2 AB cats, with concordant results (r = 1, P < .005) by flow cytometry and immunochromatographic strip kit. The plasma from type A cats had either no or weak anti‐B alloantibodies. The plasma of 12 of 13 type B cats contained strong anti‐A alloantibodies. For crossmatching, plasma to RBC pairings were prepared using the GC (n = 446) and AGC (n = 630) tests. Both methods showed compatibilities in 329 and incompatibilities in 102 pairings including all A‐B mismatches. Additionally 15 pairings showed agglutination by the AGC but not GC method. Fourteen incompatibilities outside the expected A‐B mismatches were only revealed by AGC. Conclusions and Clinical Importance AB typing using immunochromatographic strip is as accurate as laboratory flow cytometry. The 2 XM methods had good agreement with additional incompatibilities being recognized by the AGC XM beyond A‐B incompatibilities. In clinic, feline AB typing and sensitive XM test kits are available and recommended before each transfusion, although the clinical implications of incompatible XM test results and clinical benefits of such crossmatching have not been documented.

Abstract
Antibody reagents have been remained as a standard approach to characterize blood group (BG) antigens in clinic. The specificity and cross-reactivity of these BG antibodies are routine detected using the gel microcolumn assay (GMA). However, the GMA is neither specific nor sensitive, thus increasing the risk of improperly matched RBC transfusions. In this work, we describe a bead-based RBC membrane antigen array to detect BG antibody-antigen binding with ∼700-fold higher sensitivity and dynamic range than the GMA. RBC membrane antigen arrays were fabricated using fragmented RBC membranes highly enriched in BG panel antigens. The arrays were then used to screen the interactions of 15 BG reagents to three antigen panels. The majority of the antibody reactions (i.e., 86.7%; 39/45) aligned with those obtained with the GMA. The six cross-reactive, nonspecific antibody reactions identified only by our arrays (i.e., 13.3%; 6/45) were confirmed by agglutination inhibition and genotyping assays. These results demonstrate that our RBC membrane antigen array has great potential in screening BG antibodies and improving the safety of RBC transfusions.

Abstract
BACKGROUND When dogs are transfused, blood compatibility testing varies widely but may include dog erythrocyte antigen (DEA) 1 typing and rarely cross-matching. OBJECTIVES Prospective study to examine naturally occurring alloantibodies against red blood cells (RBCs) and alloimmunization by transfusion using 2 antiglobulin-enhanced cross-match tests. ANIMALS Eighty client-owned anemic, 72 donor, and 7 control dogs. METHODS All dogs were typed for DEA 1 and some also for DEA 4 and DEA 7. Major cross-match tests with canine antiglobulin-enhanced immunochromatographic strip and gel columns were performed 26-129 days post-transfusion (median, 39 days); some dogs had an additional early evaluation 11-22 days post-transfusion (median, 16 days). Plasma from alloimmunized recipients was cross-matched against RBCs from 34 donor and control dogs. RESULTS The 2 cross-match methods gave entirely concordant results. All 126 pretransfusion cross-match results for the 80 anemic recipients were compatible, but 54 dogs died or were lost to follow up. Among the 26 recipients with follow-up, 1 dog accidently received DEA 1-mismatched blood and became cross-match-incompatible post-transfusion. Eleven of the 25 DEA 1-matched recipients (44%) became incompatible against other RBC antigens. No naturally occurring anti-DEA 7 alloantibodies were detected in DEA 7- dogs. CONCLUSIONS AND CLINICAL IMPORTANCE The antiglobulin-enhanced immunochromatographic strip cross-match and laboratory gel column techniques identified no naturally occurring alloantibodies against RBC antigens, but a high degree of post-transfusion alloimmunization in dogs. Cross-matching is warranted in any dog that has been previously transfused independent of initial DEA 1 typing and cross-matching results before the first transfusion event.

Abstract
Pretransfusion testing is very important to prevent transfusion of incompatible red cells, which might result in a hemolytic transfusion reaction. This includes the detection of antibodies in recipients' serum and compatibility testing between donor cells and recipient serum. The most commonly used methods include gel and tube techniques. We present a case in which an anti-E alloantibody was detected by gel method but not by tube testing. As a result, red cells that were retrospectively phenotyped as positive for E antigen were inadvertently selected and transfused after crossmatch using the same tube method. After transfusion, the patient developed signs of hemolytic transfusion reaction. This case highlights the potential risk of transfusion of incompatible red cells when alloantibody detection is solely relied on tube testing.

Abstract
There have been rapid technological advances in blood banking in South Asian region over the past decade with an increasing emphasis on quality and safety of blood products. The conventional test tube technique has given way to newer techniques such as column agglutination technique, solid phase red cell adherence assay, and erythrocyte-magnetized technique. These new technologies are adaptable to automation and major manufacturers in this field have come up with semi and fully automated equipments for immunohematology tests in the blood bank. Automation improves the objectivity and reproducibility of tests. It reduces human errors in patient identification and transcription errors. Documentation and traceability of tests, reagents and processes and archiving of results is another major advantage of automation. Shifting from manual methods to automation is a major undertaking for any transfusion service to provide quality patient care with lesser turnaround time for their ever increasing workload. This article discusses the various issues involved in the process.

Background The aim of this study was to compare a gel-based test with the traditional direct agglutination test (DAT) for the diagnosis of immune-mediated haemolytic anaemia (IMHA). Methods Canine (n = 247) and feline (n = 74) blood samples were submitted for DAT testing to two laboratories. A subset of canine samples was categorized as having idiopathic IMHA, secondary IMHA, or no IMHA. Results The kappa values for agreement between the tests were in one laboratory 0.86 for canine and 0.58 for feline samples, and in the other 0.48 for canine samples. The lower agreement in the second laboratory was caused by a high number of positive canine DATs for which the gel test was negative. This group included significantly more dogs with secondary IMHA. Conclusions The gel test might be used as a screening test for idiopathic IMHA and is less often positive in secondary IMHA than the DAT.

Abstract
The Coombs' test can detect both immunoglobulin and complement on the surface of RBCs, and as such can be of value as an aid in the diagnosis of IMHA. Techniques that may improve sensitivity include use of monovalent reagents, increased dilutions of antiglobulin to avoid a prozone effect, and testing at 4°C. These techniques are not without controversy, and positive tests should always be interpreted in the presence of other clinical and hematologic evidence for IMHA. Alternate techniques, such as flow cytometry, can improve detection of RBC-bound immunoglobulin, but require a flow cytometer and further standardization between laboratories.

Abstract
The humoral arm of the immune system provides robust protection against extracellular pathogens via the production of antibody molecules that neutralize or facilitate the destruction of microorganisms. However, the humoral immune system also provides a significant barrier to solid organ transplantation due to the antibody-mediated recognition of non-self proteins and carbohydrates expressed on transplanted organs. Historically, the presence of donor-specific antibodies (DSA) that recognize donor HLA molecules, incompatible ABO blood group antigens and other endothelial or xenogeneic antigens was considered a contraindication to transplantation. However, recent advances in antibody testing and immunosuppressive therapies have made it possible to cross certain antibody barriers successfully. In this article, we review our current understanding of antibody-mediated processes in solid organ transplantation and discuss the clinically available treatment options for preventing and treating antibody-mediated rejection.

Abstract
Autoimmune hemolytic anemia (AIHA) is characterized by the presence of autoantibodies, most frequently of the IgG isotype, directed against erythrocyte surface antigens. The direct antiglobulin test (DAT) is the critical laboratory test for the diagnosis of AIHA, but is negative in 3-11% of cases. In these cases of DAT negative AIHA, a wider spectrum of clinical data including more specialized testing for erythrocyte autoantibodies may be required. We describe the unique and challenging case of an infant with corticosteroid-responsive, DAT negative AIHA, in which specialized gel card testing identified an isolated IgA autoantibody on the erythrocyte surface.

Abstract
Recipients of ABO incompatible allogeneic HSCT present with unusual ABO groups and crossmatch problems accompanied by change of the ABO group from that of the host to the donor. We report on a patient undergoing major ABO incompatible allogeneic HSCT (donor/recipient: A/O) whose blood group was wrongly established to have completely switched to blood group A when using a routine tube method and micro gel column blood grouping card on the 68th day post transplantation. The major crossmatch test with added antiglobulin and blood group A red cells was still positive. After further investigation, an explanation was found because we could not detect IgG anti-A in the serum. At the same time, anti-A coated the patient's RBCs and could be identified using a heat elution method although the DAT was negative. We also found an obvious mixed field with the LISS-IAT gel card. Hence, routine methods of ABO grouping are unfit for ABO incompatible allogeneic HSCT patients and a micro column neutral gel card is recommended for forward typing especially to detect mixed fields and a LISS-IAT gel card or IAT tube method for detecting IgG anti-A/B in reverse typing.

Abstract
Hemolytic anemia (HA) is not an exceptional situation in adults. While establishing the hemolytic mechanism of an anemia is usually rather easy, finding the etiology may be quite difficult as both some hereditary (corpuscular) and acquired causes of HA may occur during adulthood. The diagnosis of HA therefore requires a multiple step procedure taking into account both patient's and family history, a careful analysis of the blood smear and a direct antiglobulin test. Based on these first data, the diagnosis procedure may then require more specific tests whose indications are discussed in this review.
