| Test Name | Normal Range | Age |
|---|---|---|
| RA-Rheumatoid Factor | < 20 IU/ml | >= 0 years |
| Result | Meaning | Common Causes |
|---|---|---|
| High RA-Factor | A positive result that often points to an autoimmune condition (where the body's immune system attacks its own tissues) | Rheumatoid arthritis (a disease causing painful, swollen joints); Sjogren's syndrome (an immune disorder causing dry eyes and mouth); systemic lupus erythematosus (an immune illness affecting joints, skin and organs) |
| Moderately raised RA-Factor | A borderline or mildly positive result that may occur without joint disease and needs clinical correlation (matching the result with symptoms) | Chronic infections (long-lasting infections like hepatitis or tuberculosis); ageing (a mild rise seen in some healthy elderly people); chronic liver disease (long-term damage to the liver) |
| Normal or negative RA-Factor | A result within the expected range, meaning no rheumatoid factor antibodies were detected in the blood | Healthy individuals (people without autoimmune disease); early rheumatoid arthritis (disease so recent that antibodies have not yet risen); seronegative arthritis (joint disease that does not produce this antibody) |
The RA Factor (Rheumatoid Factor) is a blood test that mainly helps diagnose rheumatoid arthritis. It also supports evaluation of joint pain, swelling and certain autoimmune conditions.
A normal or negative result is generally below 14 IU/ml. Values of 14 IU/ml or above are considered elevated or positive. Always confirm the reference range printed on your Pathofast report.
A positive result suggests rheumatoid arthritis but is not conclusive on its own. Your doctor will combine it with your symptoms and other tests before confirming any diagnosis.
