Patient has atypical red cell antibodies. Blood will not be available in an emergency.
When requesting blood for this patient, please submit at least 2 full 10-15 ml red top tubes and allow a minimum of 2 hours for the Blood Bank to find compatible blood for this patient.
Under normal circumstances, this will be sufficient time to locate two units of blood.

| PARAGRAPH 1 |
This could mean 1 of 3 things:
1. The sensitivity of the test is limited and the amount of antibody attached to the red cells is insufficient to produce a serological reaction even when a concentrated eluate is prepared.
2. The antibody is directed against some medication which the patient is receiving and, therefore, does not react with the reagent red cells in the absence of the drug.
3. Only C3 was attached to the cells; therefore, no antibody could be recovered.
