Step 1 Repeat the test Step 2 Request a new specimen Read the Forward Type first Look at the strongest reactions The strong vs weak reactions can provide important clues 1 Repeat the test to rule out technical errors 2 If the results are the same record the result as Discrepant ABO blood group typing using anti A and anti B test sera is known as direct or forward grouping test Reverse grouping uses red cell reagents of known ABO antigen specificity to indicate the presence or absence of anti A and anti B isoagglutinins the results of which determine the reverse group Discrepancies between forward and reverse
Blood groups compatibility chart Here is the blood compatibility chart O Negative is the universal donor blood group while AB positive is the universal receiver blood group Rh refers to the presence or absence of the D antigen on the red blood cell Production of antibody to D requires exposure to the antigen The D antigen is very immunogenic i e individuals exposed to it will very likely make an antibody to it For this reason all individuals are typed for D if negative must receive Rh D negative blood

Reverse grouping is defined as using the reagent cells with known ABO antigens and testing the patient s serum for ABO group antibodies It is a type of laboratory technique used to confirm ABO blood group based on the presence or absence of anti A and anti B in serum by utilizing known A and B red cells Reverse typing A blood typing procedure where patient serum is mixed with reagent A cells and reagent B cells The results should be the opposite of forward typing Serum The straw colored fluid remaining when blood is clotted Serum does not contain any clot ting factors
Find reverse cells that type as M so the unexpected alloantibody does not interfere with the reverse typing Patient is group A Rh positive The M antigen present on the original reverse cells is what interfered with the patient s ABO reverse typing If the ABO cannot be resolved the patient needs to be transfused with Group O red blood cells All discrepancies should be resolved before blood products are issued unless there is an emergency If transfusion is required before resolution group O products should be supplied Some A 2 individuals have anti A 1 Anti A 1 is usually a cold reacting IgM and is of no clinical significance unless it reacts at 37 C Test at pH 6 or 8 5
