Next Generation Sequencing (NGS) · Dermatology
Useful in the diagnosis of suspected autoimmune disease, connective
tissue disease and vasculitis, the direct technique utilizes specific
antibodies that have been conjugated with a fluorochrome (FITC).
The antisera are incubated with the tissue sections, washed and cover
slipped. Using a fluorescent microscope, specific positive staining can
be observed as apple-green staining of the antigenic sites.

Proteins tested: IgG, IgA, IgM, C3, Fibrinogen
