On the NHS, your GP can arrange first-line blood tests such as ANA and inflammation markers and refer you on if needed. Privately, you can book a rheumatology or autoimmune blood test profile directly with a clinic.
At London Private Ultrasound our rheumatology screening includes ANA, the first-line screen for lupus and other connective tissue disease, with rheumatoid factor, anti-CCP, ESR, CRP, a full blood count and uric acid, plus a joint ultrasound and a GP consultation. If your ANA is positive, more specific tests, such as an ENA panel, may be recommended.
