ABO Grouping
Also known as: Blood Grouping, Blood Type
Use
Determination of ABO blood group for transfusion candidates. Blood grouping of expectant mothers and newborns may indicate potential for ABO hemolytic disease of the fetus/newborn.
Special Instructions
If a CBC and/or an antibody screening test is ordered with this test, please submit a separate 4 mL specimen for each test.
Limitations
The presence of abnormal plasma proteins, cold autoagglutinins, a positive direct antiglobulin test, and in some cases bacteria in the specimen can interfere with the accurate interpretation of the ABO Grouping test results. Proper sample handling and collection are critical to minimize these interferences.
