Most blood bankers really dislike ABO discrepancies, but Nicole Draper says, "They're not so bad!". She teaches three simple rules that will get you on the road to solving most of these cases quickly. When ABO testing goes right, as it almost always does, it's a very simple process. The forward grouping agrees with the reverse grouping

Describe appropriate follow-up testing that is necessary in the resolution of ABO discrepancies. A very important part of pretransfusion testing involves detection, recognition, and resolution of ABO discrepancies. Discrepant results must be identified and the underlying causes investigated. Step 1: Repeat the test. Technical errors.

This is an important distinction between an ABO discrepancy caused by acquired B and one caused by a cold-reacting autoagglutinin, which we will discuss more in a future presentation about ABO discrepancies. Third, the technologist can use a different form of monoclonal anti-B in the patient's red cell grouping test. Certain clones are known

ABO discrepancies describe unexpected reactions in forward or reverse groupings. Serum and RBC reactions are usually very strong (3+ or 4+) Weak reactions usually indicate an ABO discrepancy. They are due to technical errors, problems with the patients RBCs, plasma or both. ABO discrepancies can be classified into the following categories:

Patient samples are routinely typed for ABO prior to transfusion. Determining the ABO group requires both red blood cell (RBC) antigen typing for A and B (forward type) and testing for anti-A and anti-B in the plasma (reverse type). An ABO discrepancy exists when the result of an ABO RBC typing, or forward type, does not agree with the result of the plasma typing, or reverse type. This brief

Notes Recommended laboratory procedures/techniques should be followed for the investigation of any discrepancy e.g. AABB Technical Manual, other practical-based textbook, or in-house established Standard Operating Procedures. Where anomalous results persist, family studies can be useful, with serological and molecular biology techniques to establish inheritance pattern and genetic background.

Resolving ABO discrepancies. Confirming a patient's medical history (eg., of an ABO-incompatible stem cell transplantation, or of recent transfusion of non-ABO identical blood products) will often provide sufficient information to resolve a discrepancy. In patients who type as A in their forward type but appear to have an anti-A in their

Causes: ABO typing discrepancies may occur due to various reasons, including: Technical errors during blood typing procedures. Genetic variations in ABO genes. Autoimmune hemolytic anemia. Rouleaux formation, which is the aggregation of red blood cells due to the presence of plasma proteins. Unexpected antibodies in the serum, such as cold

https://www.ualberta.ca/~pletendr/tm-modules/abo/70abo-discrepancies.html
Although not mentioned for each discrepancy discussed, the first step in resolving a discrepancy would be to repeat the ABO group using a fresh aliquot of washed red cells. Reactions that were unexpectedly weak or negative would be read microscopically. Some labs may then incubate at 4°C since ABO antibodies react best in the cold.

Rabbit Erythrocyte Stroma is used to adsorb cold reactive autoagglutins. Not used for ABO typing because Anti-B will be completely or partially adsorbed out. Patient is group A, Rh positive. 63 year old; Caucasian Male. Hgb 6.5. Has cancer but no medication list provided. Multiple transfusions in the last 3 months.

Recognizing and resolving ABO discrepancies. Patient samples are routinely typed for ABO prior to transfusion.

ABO Discrepancies: ABO discrepancies happen when there is no match in results between. forward and reverse grouping (Cell type and Back type). Since production of ABO antigens is genetically controlled, they are less. vulnerable to problems than does the production of ABO antibodies. Therefore we see more problems in Reverse grouping.

ABO discrepancies are common obstacles health care professionals encounter in clinical practice. ABO discrepancies describe scenarios that result in unexpected reactions in the ABO forward and reverse typing reactions. ... If, despite these steps, a reaction is still not obvious, then the mixture of the patient's serum and reagent cells should

https://pressbooks.nscc.ca/transfusion/chapter/resolving-abo-anomalies/
We never "assume " the patient's ABO. The discrepancy must be resolved. If blood is needed before the discrepancy is resolved, Group O red cells and group AB plasma must be transfused. There are four major types of anomalies: An expected antibody may be weak or missing. An unexpected antibody may be present.

The next step in resolving this discrepancy would be to: Incubate reverse tubes at room temperature for 15 minutes. Prewarm the patient's plasma and reverse grouping. Perform absorption/elution studies using the patient's. Incubate the anti-A tube and the A1 cell tube at room temperature for 15. An 83 year old woman was brought to the

The following guidelines may help with ABO discrepancy resolution: ABO reactions with reagent antisera and red cells are generally strong (3 - 4+); weak reactions should be noted. Mixed field reactions are not typically expected when performing ABO forward typing. Patient history and clinical data often provide hints regarding possible
