LETTER TEXT |
Patient has atypical red cell antibodies.
Blood will not be available in an emergency since, unless otherwise noted, the patient must continue to receive antigen negative blood even though the antibody may not always be demonstrable by routine techniques.
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 wil be sufficient time to locate two units of blood. If the % compatible (noted below) is less than 5%, more time may be needed.
