CSPL offers direct immunofluorescence testing on skin biopsies for the diagnosis of bullous and autoimmune diseases. Our panel of antibodies includes IgG, IgA, IgM, C3, and fibrinogen.
Transport media for immunofluorescence studies can be requested from CSPL.
Label the vial properly- Provide pertinent clinical information (perilesional, lesional, etc)- Do not place biopsy in formalin, even if only for a few seconds, the biopsy will be unusable- Biopsies in IF Fixative can remain refrigerated- Paired specimens (H&E) will optimize the diagnostic process. Please send the biopsy to our lab within one week after placing in fixative.
Turnaround Times:
Samples are completely processed within 3 business day after receipt.
Transport Medium:
We will supply you with the appropriate fixative (Michel’s media). A sample placed in formalin, even for a few seconds, could be read falsely negative.
Taking the Biopsy:
- A 4mm punch biopsy is preferred; however, a deep shave or saucerization into reticular dermis may also be acceptable for processing.
- Biopsies should be taken from peri-lesional skin (dermatitis herpertiformis, bullous pemphigoid, pemphigus) or involved skin in an erythematous area or an active border (LE, vasculitis, PCT, LPP).
- It is best to avoid older lesions or ulcers.
- For pemphigus or pemphigoid, if possible, avoid the lower extremity biopsies.
- Make sure the biopsy is not adherent to the lid or side of the vial and is fully immersed in fixative before tightening the vial lid.
