4-Color Flow Cytometric Crossmatch Using Whole Blood Lysis.

In lymphocyte crossmatch using flow cytometry (flow cytometric crossmatch, FCXM), the conventional tricolor FCXM protocol requires a mononuclear cell isolation step. To develop a new, more streamlined... A total of 186 donor/recipient pairs for transplantation were classified into donor-specific human leukocyte antigen (HLA) alloantibody-positive (DSA+, n = 78) and DSA-negative (DSA-, n = 108) groups.... WBL FCXM showed no difference quantitatively compared with conventional FCXM, except for the B cell FCXM in the DSA- group (B cell MFI ratio: 1.06 ± 0.44 and 0.92 ± 0.41, respectively [P = .0001]). Th... WBL FCXM demonstrated comparable assay performance to that of conventional FCXM. Because this new FCXM protocol is simple and does not compromise assay sensitivity, it has the potential to replace the...

Patient ABO blood type is a major predictor of a positive DAT following a transfusion reaction.

A direct antiglobulin test (DAT) checks for antibody or complement on the surface of RBCs and is often done following a transfusion reaction. While passive anti-A and anti-B antibodies are known to ca... DAT results, ABO type, eluate information, and blood product information were recorded on 1097 transfusion reactions at a large academic hospital over 8 years. The effect of patient blood type, produc... Patient ABO blood type was a strong predictor of a positive DAT, with type O patients having 6.7% positive rate and non-O patients having a positive rate of 20.6% (p < .0001). Plasma compatibility of ... These results demonstrate the patient ABO type and plasma incompatibility are strong predictors of positive DAT results following a transfusion reaction. Anti-A and anti-B antibodies are estimated to ...

Multicenter evaluation of a high-throughput microarray platform for extensive red blood cell phenotyping and antibody screening.

Blood typing and antibody screening are key elements of transfusion safety. However, available single platform, flexible, and affordable technologies are limited, especially for extended phenotyping. ... This study was conducted in three blood donor laboratories to determine the performance of a high-throughput microarray-based system for ABO, RH1-RH5, and KEL1 typing, ABS and extended phenotyping (RH... In total, 4862 blood samples were tested for standard phenotype, 4257 for antibody screening and 2194 for extended phenotype. Results were available for 92.12% of the samples.
