Estimated cost for Rheumatoid Factor Panel at general public hospitals in China is about ¥15-40, and at Grade 3A hospitals about ¥20-50, varying by hospital tier and region.
Main Uses
The Rheumatoid Three Tests (RF, CRP, ESR) are primarily used for diagnosing and monitoring the progression of rheumatoid arthritis and other inflammatory or autoimmune conditions. They help in assessing the level of inflammation in the body and can guide treatment decisions.
Normal Range
The Rheumatoid Factor (RF) should be <20 IU/mL, C-Reactive Protein (CRP) should be <1.0 mg/dL, and Erythrocyte Sedimentation Rate (ESR) for males is 0-15 mm/hr and for females is 0-20 mm/hr.
Low Values - Possible Causes
Low values are less common and usually not clinically significant; however, they can sometimes indicate a lack of inflammatory or autoimmune activity, successful treatment of an existing condition, or in the case of RF, simply mean that the individual does not have rheumatoid arthritis or another RF-positive condition.
High Values - Possible Causes
High RF levels may indicate rheumatoid arthritis, Sjögren's syndrome, or other autoimmune diseases. Elevated CRP suggests inflammation, infection, or tissue damage. An increased ESR can point to conditions like infections, inflammations, malignancies, or autoimmune diseases.
