An exhaustive support for clinical and differential diagnosis of vasculitides is given by DOT kits listed in this section.

ANCA-GBM-dot-3 kit is an example; with its three antigens (MPO, PR3, GBM) coated in single dots on nitrocellulose strips, this kit represents a valid aid for diagnosis and differentiation of various forms of autoimmune vasculitides such as Microscopic Polyangiitis, Goodpasture Syndrome and Wegener’s Granulomatosis.
