IMMUNOHEMATOLOGY & TRANSFUSION SERVICES>TS 23 RIs there documentation of the visual inspection o units of blood and blood components prior to shipment orrelease for transfusion?Quality ControlTS 24 EAre ABO antisera checked with a positive control each day of use and are the results documented?An easy way to do QC on ABO reagent red cells (antigens) and ABO reagent antisera (antibodies) is to useeach to QC the other. By reacting A cells with anti-A and anti-B and B cells with anti-A and anti-B, you havesuccessfully cross-check each reagent.TS 25 EAre Rh antisera checked with positive and negative controls each day of use and are the results documented?TS 26 EIf the laboratory uses a protein based Rh antisera, is a special protein based control reagent, similar to theformulation of the Rh antisera in use, performed to detect possible false positive Rh tests and are the resultsof this testing documented?There are different types of Rh Antisera. The most common reagents presently in use are saline based,monoclonal antisera. These products do not require the use of a separate control to detect false positive Rh tests.Laboratories still using a protein based antisera, should consult the manufacturer’s instructions for selectionof a protein based reagent that matches the formulation of the Rh antisera in use. The laboratory will incubatepatient cells with the protein based reagent to detect spontaneous agglutination that may contribute to afalse positive result. The patient’s Rh test and the control procedure described above must be performedsimultaneously.TS 27 EAre all other antisera in use checked with positive and negative controls each day of use and are the resultsdocumented?TS 28 EIs ABO reagent red cells checked with a positive control each day of use and are the results documented?An easy way to do QC on ABO reagent red cells (antigens) and ABO reagent antisera (antibodies) is to useeach to QC the other. By reacting A cells with anti-A and anti-B and B cells with anti-A and anti-B, you havesuccessfully cross-check each reagent.TS 29 EAre antibody screening cells checked with a positive control containing at least one known antibody each dayof use and are the results documented?. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .FOR MORE INFORMATION CONTACT COLA PHONE 800.981.9883 | FAX 410.381.8611 | ON-LINE www.cola.org67
