We are inspected by TJC for the lab. They are citing some of the other hospitals in the system using this standard. QSA.05.06.01 The laboratory conducts reactivity testing on the potency and reliability of reagents used for ABO grouping, Rh typing, antibody detection, and compatibility determinations. 2 Each day the procedure is performed, and when a new lot of reagents is first used, the laboratory tests each opened vial of antisera, reactive cells, and reagents for reactivity. The reactivity results are documented. I guess it depends on the inspector but since we are inspected this year I would like to comply if they are really citing labs.
