Phenotype antigen Jkb

Clinical information

Diagnostic Utility:

This test is used to determine whether the Jk^b antigen is present or absent on erythrocytes. It is part of the erythrocyte phenotype study. It is also useful in the investigation of irregular antibody specificities to demonstrate that in the presence of an anti-Jk^b specificity, the person who developed the antibody is Jk^b negative.

Method:                                             

Hemagglutination.

Reference Values

Possible results are: Negative, Positive.
In case of doubtful results, for example due to recent transfusions, this will be reported and the need for further studies to unequivocally categorize the Jk^b phenotype will be indicated.

Diagnostic Algorithm:

Not applicable.

Turnaround Time:

1 day.
