We are puzzled by CAP question ANP.21850.  It suggests the use of
internal controls for renal bxs.  We do Direct Immunofluorescence on
skin biopsies only.  What internal controls are other people using for
their skin bxs?.  Also, has anyone found a source for a positive sausage
control for DIF?  What are other people using for their positive
controls?  Thanks for the help. Rosemary
