Clinical staff usually refer to these tests as “type and screen” or “type and cross,” which are two different but similar types of pretransfusion tests.

MODULE Pretransfusion or Compatibility Testing Hematology and Blood Bank Technique HEMATOLOGY AND BLOOD BANK TECHNIQUE Notes IV. Selection of blood Donor blood on which ABO and Rh grouping and screening for various transfusion transmitted infections has been done is selected for transfusion. Automation has increasingly been adopted in clinical laboratories and blood banks, providing alternatives to the traditional method of manual tube testing for pre-transfusion testing. Pre-transfusion testing techniques all have advantages and limitations; it is important to identify scenarios where the traditional tube testing technique should be applied to mitigate limitations of other methods.

Tests other than direct agglutination and/or IAT are not normally required for compatibility testing, unless the sensitivity of the IAT is known to be unreliable. Enzyme and albumin techniques that have a high rate of ‘false positive’ reactions, add to workload and cost, can delay transfusion unnecessarily, and carry the risk of introducing. PRETRANSFUSION TESTING INFORMATION Catholic Medical Center Laboratory, McGregor Street, Manchester, NH Patients requiring pretransfusion testing are required to be identified using the Yellow (Red or Green) Blood Bank (BB) Identification (ID) Bracelet. This helps prevent potentially fatal transfusion errors due to. series of tests performed to prevent administration of incompatible donor blood products which may cause acute or delayed hemolytic transfusion reactions 1,2; routine pretransfusion tests include 1,2.
