Anti-C1q or urticarial vasculitis is a form of cutaneous vasculitis characterised by inflammation of the small blood vessels. Urticarial Vasculitis can be classified into three subtypes. All are defined by a measure of the "complement" levels in the blood. The complement system is a set of proteins that contribute to and amplify immune responses.

Other important autoantibodies in primary small vessel vasculitis are anti-glomerular basement membrane antibodies, anti-C1q, anti-galactose deficient IgA and cryoglobulins. A wide variety of systemic inflammatory diseases and infections can be complicated by small vessel vasculitis and detected by serological testing.

Testing for C1q, anti-C1q, C3 and C4 complement components is essential to determine the type of Urticarial Vasculitis. Tests may also be done for Anti-Nuclear Antibody (ANA) levels (which are positive in 30 to 50 per cent of patients), and Anti ds-DNA levels may also be positive.
