Revalidating immuno reagents

From:"Nocito, Joseph" <>

Good morning all,
	During the last two days, we have been inspected by CLIA. The
inspector found an expired immuno reagent in the refrigerator (I know, shame
on me).  I explained to this person that although the reagent is expired, I
always run a known positive control with each run.  If the control didn't
work, the case is repeated with another lot number. This was not good enough
for this person. She wanted proof.  Short of performing a short immuno run
in front of this person, I couldn't site any references.
	Does any one have a procedure that can be referenced dealing with
validaing and re-validating reagents?  I'll also mention that each primary
antibody gets titered upon receipt and each new detection kit gets tested
and the results recorded before it is put into use.
	Thanks in advance.
