[Histonet] DIF Controls

[Steve Weaver]

**New** CAP Question: ANP.21850  "Are appropriate positive and negative
controls performed with each case tested using immunofluorescence?"
We currently just run one (+) control, usually IgG or C3, for the entire
run that includes IgA, IgG, IgM, C3, C4 and fibrinogen.  My question is
- should I be running (+) controls for all antibodies?  Your thoughts
please.  Please indicate if you have been inspected on this new
question.  Thank you. sw
