Phenotype antigen Kpb

Clinical information

Diagnostic Utility:

This is a high-frequency antigen. Its determination serves to determine whether the Kp^b antigen is present or not in the red blood cells. It is part of the red cell phenotype study. It is also useful in the study of the specificity of irregular antibodies to demonstrate that in the presence of an anti-Kp^b specificity, the person who has developed the antibody is Kp^b negative.

Method:                                             

Hemagglutination.

Reference Values

Possible results are: Negative, Positive.
If the result is doubtful, for example due to recent transfusions or because the sample has a positive direct antiglobulin test, it is reported and additional studies are indicated to unequivocally determine the Kp^b phenotype.

Diagnostic Algorithm:

Not applicable.

Turnaround Time:

1 day.
