Posted March 29, 20241 yr comment_88254 I see TJC standard QSA.05.06.01 now says: Each day the procedure is performed, and when a new lot of reagents is first used, the laboratory tests at least one vial from each lot number of antisera, reactive cells, and reagents for reactivity. The reactivity results are documented. Note: This testing includes positive and negative reactivity when recommended by the manufacturer. We have always thought that JC requires QC on all open vials even if they are the same lot number. Does anyone know when this changed? Or is there a different standard that contradicts it?
