ABO blood group system

This study was carried out to determine any association between ABO grouping and Rhesus (Rh) typing in patients with PTB (both sputum positive and negative) and EPTB.

The process of pretransfusion compatibility testing involves many steps: receipt of orders for testing, sample acceptability criteria review, ABO grouping, rhesus (Rh) typing, red cell antibody screening, unexpected antibody identification, selection of appropriate donor red blood cell units, and, for some patients, crossmatching with the unit to be transfused.

Hence, we did a retrospective analysis of records of ABO grouping and Rh-D typing of the blood donors, transfusion recipients and patients attending antenatal care or some other medical interventions at Silchar Medical College and Hospital Blood Bank, Silchar, over a period of 10 years from 1st January 1999 to 31st December 2008.

Tenders are invited for The Primary Function Of This Automate/S Is To Perform :- Abo Grouping And Rhd Typing, Including A Reverse Type Using A1 And B Cells.

On the other hand, it is important to be sure that every technologist can recognize an ABO grouping discrepancy or mixed field agglutination.

In male donors, ABO grouping followed the same frequency pattern (B>O>A>AB).

In other words, perform the ABO grouping on the intended recipient a second time and dispense with crossmatching entirely.
