Private Rheumatology Profile 6 (Rheumatoid Plus) Test in the City of London

Autoimmune conditions occur when the immune system mistakenly attacks the body's own tissues. There are over 80 recognised autoimmune conditions, affecting joints, skin, organs, and other body systems.

Blood tests for autoimmune markers, including autoantibodies, can assist in the investigation of suspected autoimmune conditions. These tests are typically used alongside clinical assessment and other investigations.

What the Rheumatology Profile 6 (Rheumatoid Plus) Measures

• Autoantibodies — proteins produced by the immune system that target the body's own tissues
• Inflammatory markers — such as CRP and ESR, which indicate systemic inflammation
• Specific antibody patterns — which may help narrow down the type of autoimmune condition

When This Test May Be Helpful

• Joint pain, stiffness, or swelling
• Skin rashes, particularly those worsened by sunlight
• Persistent fatigue alongside other symptoms
• Dry eyes or dry mouth
• A family history of autoimmune conditions
• Unexplained organ involvement (e.g. kidney, lung)
• Investigating symptoms suggested by a clinician

Understanding Your Results

Results are typically available within 3 days" and are delivered securely.

A positive autoantibody result means that certain antibodies have been detected in your blood. However, autoantibodies can be present in healthy individuals without causing disease, and a positive result does not confirm an autoimmune diagnosis.

Autoimmune test results must be interpreted by a clinician alongside your symptoms, physical examination, and other investigations. We recommend discussing your results with your GP or a rheumatologist.
