What this test is
This panel includes several blood markers that can indicate inflammation or autoimmune activity. It is not a single test but a group of tests that your clinician may order together or individually.
What it measures
- C-reactive protein (CRP) — a general marker of inflammation in the body
- Erythrocyte sedimentation rate (ESR) — an indirect measure of inflammation
- Rheumatoid factor (RF) — an antibody often associated with rheumatoid arthritis
- Anti-cyclic citrullinated peptide (anti-CCP) — an antibody that can support a rheumatoid arthritis diagnosis
- Antinuclear antibodies (ANA) — a marker that may suggest an autoimmune process
- Uric acid — a substance that can be elevated in gout
What the test involves
A standard blood draw from a vein in your arm is used for these tests. No special collection method beyond routine phlebotomy is required.
Why it is often ordered
A clinician may order these tests to help evaluate persistent joint pain, swelling, or stiffness. They can also be used to monitor known inflammatory conditions over time.
Preparation
Follow the collection lab's instructions regarding fasting or medication timing. Specific preparation can vary by the tests included and the lab performing them.
How results are reported
Results are typically reported as numeric values with a reference range for each marker. Reference ranges vary by laboratory, so your results should be interpreted in the context of the lab that performed the testing.
