ABO/Rh(D) Group

Clinical information

Diagnostic Utility:

This is the most important erythrocyte blood group and its determination is useful in:

• Blood transfusion
• Monitoring pregnant women
• Transplantation of progenitor cells, solid organs, and tissues

Method:

Hemagglutination. The blood group and serological group are determined.

Reference Values

Possible results are: A Positive, A Negative, O Positive, O Negative, B Positive, B Negative, AB Positive, AB Negative.
In some cases, it is not possible to obtain any of these results due to a discrepancy between the blood group and the serological group.

Diagnostic Algorithm:

In case of discrepancy between the blood group and the serological group, and in order to obtain an unequivocal result, the cause must be investigated using test 0017: ABO Group Discrepancy Study.

(*) When the requesting centre has already detected the serological discrepancy, it can directly request the performance of this test.

Response Time:

1 day. Serological discrepancy studies may require more time.
