Dear Clinical Heme-type flow people

After a recent lab accrediting survey by JCHAO, it was suggested that an
'abnormal' control be routinely run on the flow cytometer. I did not have
an opportunity to clarify precisely what this meant with the JCHAO
investigator. Does anyone have specific experience with this request?

thank you
