IMMUNOHEMATOLOGY & TRANSFUSION SERVICESCompatibility TestingTS 41 RPrior to compatibility testing, are all units of whole blood and red blood cell components retyped to confirmABO group and Rh D negative labeling from an attached segment?Some transfusion services perform retypes as units are received from the blood supplier and some do themas the crossmatch is being performed. Either is acceptable as long as it is documented. Tests to confirm Rhpositive labeling or tests to confirm for weak D are not required.TS 42 EAre recipient’s historical records reviewed and documented prior to selecting units for transfusion?TS 43 RDoes the procedure manual include criteria for selecting appropriate ABO and Rh types of red blood cells andcomponents for patient transfusion?TS 44 EAre all donor cells cross-matched with recipient serum or plasma prior to transfusion?Immediate spin crossmatch only detects ABO incompatibility and is adequate only if both donor and recipienttest negative for clinically significant red cell antibodies and there is no record of previously detected red cellantibodies. It is also adequate in life-threatening emergencies, or for autologous or neonatal transfusions.If a crossmatch is performed at another facility and the unexpected antibody screen was negative, the administeringfacility need only confirm ABO compatibility.TS 45 EAre an antigen screen of the donor unit and a major crossmatch performed prior to release of a unit for transfusionwhen the antibody screen of the recipient was positive for clinically significant red cell antibodies?Computerized SystemsTS 46 EIf a computerized compatibility testing and record keeping system is in use has the system been validatedonsite according to accepted protocol?Your system should:• Be used only when ABO compatibility testing is required.• Be used only if there are two separate determinations of a recipient’s ABO group.• Contain donor unit number.• Contain component type/name, e.g. frozen red cells.• Contain ABO group of donor.• Contain Rh type of donor.• Contain interpretation of ABO confirmatory test.• Contain recipient identification.• Contain recipient ABO group and Rh type.• Have a method to verify correct entry of all of the above data.• Have system logic to alert for discrepancies between donor/recipient information and potential incompatibility.70. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .FOR MORE INFORMATION CONTACT COLA PHONE 800.981.9883 | FAX 410.381.8611 | ON-LINE www.cola.org
