Background and objective RhD variants show altered D antigen expression, affecting their serological detection. Proper identification is crucial due to potential anti-D antibody formation. This study aimed to retrospectively analyze the frequency and characteristics of D variant cases encountered during RhD typing in both blood donors and recipients and the transfusion implications.

Still, anti-D is reported to be the most common cause of HDN in India. ABO incompatibility has emerged as a leading cause of exchange transfusion (ET) in many countries.

Still, ABO incompatibility and other alloantibodies against minor blood group antigens have emerged as significant causes of HDN. Moreover, ABO incompatibility acts as a protective barrier to the expression of Rh isoimmunization.

Teleporting is a popular interface to allow virtual reality users to explore environments that are larger than the available walking space. When teleporting, the user positions a marker in the virtual environment and is instantly transported without any self-motion cues. Five experiments were designed to evaluate the spatial cognitive consequences of teleporting and to identify environmental cues that could mitigate those costs.

Introduction: The authors' center recently changed their pretransfusion testing protocol from "conventional" type and screen (TS) with anti-human globulin (AHG) crossmatch (Policy A) to TS with immediate-spin (IS) crossmatch (Policy B). Red blood cell (RBC) units were issued after compatible IS crossmatch as and when required instead of AHG crossmatch. This study was conducted to compare the effects of change of policy from A to B over 1-year period on crossmatch-to-transfusion (C/T) ratio, RBC issue turnaround time (TAT), outdating of RBC, man-hours consumption, and monetary savings.

Indications for therapeutic apheresis (TA) are dynamic; they keep changing and expanding because of introduction of newer treatment modalities and accumulating evidence in the form of case-reports, case-series and original articles. We evaluated our therapeutic plasmapheresis (TP) data and compared this data with an earlier published Indian report for indications, frequency, response rate and adverse reactions. We conducted a retrospective analysis of all TP procedures performed from January 2014 to June 2016 in department of Transfusion Medicine at a tertiary care hospital.

When one antibody has been identified, it becomes necessary to confirm the presence of additional significant antibodies to ensure that compatible blood is provided to the patient. To perform this confirmation, specific reagent red blood cells (RBCs) are selected; these are called selected cells.

Co-infection is significant as it leads to accelerated disease progression. We, therefore, evaluated the prevalence of co-infection among blood donors.

Development of antibodies against red blood cell (RBC) antigen which may be alloantibody or autoantibody, several times as a result of frequent red cell component transfusions, further complicates the subsequent transfusion therapy. Among the autoantibodies, warm-reactive autoantibodies are commoner and interfere in the pretransfusion testing.

He was advised bone marrow transplant (BMT) and had 6/6 match with a younger sibling (11 months old). He was admitted for planned BMT and was put on preparatory regimen five days prior to BMT.
