Rheumatoid Arthritis Diagnostic IdentRA® Panel 2

The Rheumatoid Arthritis Diagnostic IdentRA® Panel 2 test contains 1 test with 3 biomarkers.

Clinical Significance

Rheumatoid Arthritis Diagnostic IdentRA® Panel 2 - Early diagnosis of rheumatoid arthritis (RA), ie, diagnosis before significant joint erosion occurs, is difficult. Psoriatic arthritis can also be difficult to diagnose clinically early in the disease process, and there are no specific biomarkers. The 14-3-3η (eta) protein is an emerging biomarker for RA and erosive psoriatic arthritis diagnosis. It may play a biologic role in the joint erosive process. Blood levels appear to be elevated in patients with RA, but not in other diseases including psoriasis, osteoporosis, gout, ulcerative colitis, type 1 diabetes, systemic lupus erythematosus, Crohn disease, primary Sjögren syndrome, scleroderma, and multiple sclerosis. The 14-3-3η protein, used in conjunction with rheumatoid factor (RF) and cyclic citrullinated peptide (CCP) antibody, may improve diagnostic sensitivity in the early diagnosis of RA. It may also help differentiate those with psoriatic arthritis joint damage from those without joint damage.

Rheumatoid Factor

Rheumatoid factor (RF) is a blood test that measures the amount of the RF antibody in the blood. An abnormal result means the test is positive, which means higher levels of rheumatoid factor have been detected in your blood. Most patients with rheumatoid arthritis or Sjogren syndrome have positive RF tests. The higher the level, the more likely one of these conditions is present. Not everyone with higher levels of rheumatoid factor has rheumatoid arthritis or Sjogren syndrome.
