Blood test to measure proteins and antibodies associated with Rheumatoid Arthritis (RA).
This test detects the presence of proteins and autoantibodies in your blood that are linked to Rheumatoid Arthritis (RA), a chronic autoimmune disease. RA causes painful inflammation in joints and other organs. Early detection is crucial for managing the disease and preventing long-term damage. The test helps determine if further investigation or treatment is needed. Specific autoantibodies measured include Mutated Citrullinated Vimentin (MCV) Antibodies, Rheumatoid Factor (RF), and Cyclic Citrullinated Peptide (CCP) autoantibodies.

Who Is This For?
Anyone with unexplained joint pain, fatigue, or recurrent symptoms that could indicate autoimmune activity. People with a family history of autoimmune diseases (lupus, rheumatoid arthritis, Hashimoto's). Health-conscious individuals tracking inflammation as part of a longevity protocol. Those recovering from illness or injury who want to monitor their inflammatory response.
What's Included
Preparation Required
No fasting required for most inflammation markers. Avoid intense exercise for 24 hours before testing, as it temporarily elevates CRP and other inflammatory markers. Inform your provider of any acute illness, injury, or infection, as these will cause temporary elevations unrelated to chronic conditions.
Biomarkers Tested
4The average size of your red blood cells. Small cells (microcytic) suggest iron deficiency, while large cells (macrocytic) may indicate vitamin B12 or folate deficiency. Normal-sized cells with low count suggest chronic disease.
Autoantibody often elevated in inflammation, e.g., rheumatoid arthritis.
A highly sensitive test for low-grade chronic inflammation linked to cardiovascular disease risk. Lower hs-CRP values are associated with better cardiovascular outcomes.
Erythrocyte sedimentation rate — measures how quickly red blood cells settle to the bottom of a test tube. Faster settling indicates more inflammation. ESR is a non-specific marker used to monitor inflammatory conditions like arthritis and vasculitis.
Includes a $6.00 Physician Service Fee. Klarna/Affirm payment options available.
