ANA Blood Test Autoimmune

Mar 8, 2026

ANA Blood Test Autoimmune

An ANA (antinuclear antibody) blood test detects antibodies that attack your own cells, screening for autoimmune conditions like systemic lupus erythematosus (SLE), Sjögren's syndrome, scleroderma, and mixed connective tissue disease—conditions where the immune system mistakenly attacks the body's own tissues. A positive ANA doesn't diagnose a specific disease but indicates the need for further investigation.

At Blood Test London, ANA testing costs from £265 with results in 2-3 days. A doctor always reviews every result, explaining what positive or negative results mean.
