Clinical information
Diagnostic Utility:
This test is used to determine whether there is presence or absence of the M antigen on red blood cells. It is part of the erythrocyte phenotyping study. It is also useful in the context of studying the specificity of irregular antibodies to demonstrate that in the presence of an anti-M specificity, the person who has developed the antibody is M negative.
Method:
Hemagglutination.
Reference Range
The possible results are: Negative, Positive.
In case of doubtful results, for example due to recent transfusions, the same will be reported and the need for complementary studies to unequivocally categorize the M phenotype will be indicated.
Diagnostic Algorithm:
Not applicable.
Turnaround Time:
1 day.
