The doctor prescribes a rheumatoid factor test to confirm whether you are suffering from certain autoimmune diseases, arthritis or other infections. Along with a rheumatoid factor test, the doctor may advise additional tests to diagnose your condition.
- Anti-cyclic citrullinated peptide (anti-CCP) test
The test is performed alongside the rheumatoid factor test. If both rheumatoid factor and anti-cyclic citrullinated peptides are detected in your blood, it means you are suffering from rheumatoid arthritis.
- C-reactive protein (CRP) test
If your blood test confirms the presence of C-reactive proteins, it indicates inflammation in your body. The reason for inflammation could be some infection or other autoimmune diseases. The doctor may prescribe additional tests for confirmation.
- Antinuclear antibody (ANA) test
The presence of the antinuclear antibody and rheumatoid factor together indicate an autoimmune disorder.
- Erythrocyte sedimentation rate (ESR) test
A higher level of ESR confirms inflammatory diseases caused by infections, rheumatoid arthritis, fever or other autoimmune disorders.
