Antigen Phenotype Fya

Code: 0520

Type: Estudis eritrocitaris

Clinical information

Diagnostic Utility:

This test is used to determine the presence or absence of the Fya antigen on red blood cells. It is part of the study of the erythrocyte phenotype. It is also useful in the context of studying the specificity of irregular antibodies to demonstrate that in the presence of an anti-Fya specificity, the individual who has developed the antibody is Fya negative.

Method:                                            

Hemagglutination.

Reference Values

Possible results are: Negative, Positive.
In cases where the result is doubtful, due to previous transfusions or because the sample has a positive direct antiglobulin test, the same is reported and the need for additional studies to unequivocally categorize the Fya phenotype is indicated.

Diagnostic Algorithm:

Not applicable.

Turnaround Time:

1 day.
