Antigen phenotype Kpa

Clinical information

Diagnostic Utility:

This test is used to determine whether or not the Kp^a antigen is present on red blood cells. It is part of the red blood cell phenotype study. It is also useful in the study of irregular antibody specificities to demonstrate that in the presence of an anti-Kp^a specificity, the person who developed the antibody is Kp^a negative.

Method: Hemagglutination.

Reference Values

Possible results are: Negative, Positive.
In case of doubtful results, for example due to recent transfusions, this is reported and further studies are recommended for an unequivocal categorization of the Kp^a phenotype.

Diagnostic Algorithm:

Not applicable.

Turnaround Time:

1 day.
