Test Details
Methodology
Hemagglutination
Result Turnaround Time
1 - 2 days
Turnaround time is defined as the usual number of days from the date of pickup of a specimen for testing to when the result is released to the ordering provider. In some cases, additional time should be allowed for additional confirmatory or additional reflex tests. Testing schedules may vary.
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
Abnormal plasma proteins, cold autoagglutinins, positive direct antiglobulin test, and, in some cases, bacteremia may interfere with test interpretation.
