Test Information
A blood type and antibody screen are performed to determine the presence of atypical antibodies in order to provide compatible red cells. If atypical antibodies are present refer to Antibody Identification. Surgical patients served by Marshfield Transfusion Service having clinically significant antibodies will have 2 Red Blood cell units crossmatched for surgery.   If the patient does not have a historical blood type in Marshfield Labs Transfusion Service computer system, a second sample may be obtained for second blood type (no charge) for improved safety when transfusing type-specific Red Cell products.
