Limitations and Contraindications

Antigen typing is dependent oncommercial antisera available.  Testing is contraindicated if the specimen is hemolyzed.  If a patient has a positive DAT, or if a patient has recently been transfused, antigen results may be invalid.  Positive DAT results may require specialized testing to identify the cause.  The sample may be sent to a reference laboratory.  If a patient has antibodies, the donor units must be antigen testing to ensure that any transfused units do not contain the antigen reactive with the patient''''''''''''''''s antibody.  False negative and false positive results can occur.

Interpretation
