Complement C2 – Private Testing in London

The Complement C2 is available at Wimpole Street Medical and Dental, our CQC-registered clinic in Marylebone, London W1G. This test is priced at £198. A £50 phlebotomy fee applies per visit for blood collection. It requires a venous blood sample, and results are typically available within 10 days.

The complement system is a group of blood proteins that assist the immune system in destroying pathogens and triggering inflammation. Complement levels help assess immune function and autoimmune disease activity.

Who Should Consider the Complement C2?

Individuals being investigated for systemic lupus erythematosus (SLE), vasculitis, or recurrent infections. Patients with known autoimmune disease being monitored for flares. Those with hereditary angioedema.

Low complement levels (especially C3 and C4) may indicate active autoimmune disease, complement deficiency, or severe liver disease. Serial measurements help track disease activity in SLE.

A trained nurse collects the blood sample by standard venepuncture, a straightforward procedure that typically takes around five minutes. Our clinic is on Wimpole Street, directly opposite Wimpole Street tube station (Piccadilly, Circle, and District lines). No GP referral is needed — book online or call 020 7183 0692.
