Discrepancy in ABO Blood Grouping in a Blood Donor: A Case Report

Authors

Abstract:

Detection of ABO blood groups through agglutination is the basis of pre-transfusion testing. However, weak agglutination reactions may be obtained with reagent antibodies and are a result of weak expression of A and B antigens on red blood cell surface which may cause a discrepancy in blood group typing. Here, we report a donor which showed discrepancy between red blood cells (forward) and serum (reverse) typing. A detailed analysis revealed the blood type as a variant of blood group B. Subgroup of B is a very rare phenotype of blood. This is the first case ever detected in Kurdistan blood transfusion Center.

Discrepancy in ABO blood grouping.

Discrepancies in blood typing is one of the major reasons in eliciting a transfusion reaction. These discrepancies can be avoided through detailed analysis for the blood typing. Here, we report a subgroup of blood group type-B in the ABO system. Donor's blood was analyzed by employing commercial antisera for blood grouping. The results of forward (known antisera) and reverse (known antigen) rea...

Yersinia enterocolitica in donor blood: a case report and review.

Routine sterility control of a unit of leukocyte-depleted erythrocyte concentrate yielded growth of Yersinia enterocolitica serotype O:3. Plasma of the donor showed a high titer of agglutinins against the homologous organism. Although the donor was apparently well at the time of donation, he had a history of protracted terminal ileitis treated by surgery. The recipient of the contaminated blood...
