JLF Posted April 6, 2018 Share Posted April 6, 2018 Has anyone heard of running two positive and two negative controls with each test run of A1 Lectin and A2 Cells? I am told by a facility it was an AABB requirement. I have found no reference for it. They are running the current in-date positive and negative control reagents plus the last, expired positive and negative control reagents. I thought using expired controls would be in violation of CAP TRM.31250 (All reagents are used within their indicated expiration date). Link to comment Share on other sites More sharing options...
Kathyang Posted April 6, 2018 Share Posted April 6, 2018 I do AABB Assessments and as far as I know you need to follow your insert. It says nothing about running 2 controls or using an expired control. The only thing I read is that in older cells, the reaction may be weaker.
