Rheumatoid Arthritis Diagnostic Panel
Two antibody markers that together pin down rheumatoid arthritis when joint pain and swelling have no clear cause.
Consider this test if:
- Persistent joint pain, morning stiffness, or symmetric swelling in the hands, wrists, or feet
- Investigating fatigue and joint symptoms that suggest an inflammatory rather than mechanical cause
- A family history of rheumatoid arthritis or other autoimmune disease alongside new joint symptoms
- Confirming or ruling out RA after an abnormal inflammatory marker or an unclear earlier result
- HSA/FSA eligible
- Results delivered to your dashboard · Reviewed by a real clinician
- Drawn at a CLIA/CAP-accredited lab near you ·
Pre-test considerations
No fasting required, and timing during the day does not matter. Results reflect antibody levels, not recent meals or activity.

What this test is for
This panel pairs rheumatoid factor (RF) with anti-cyclic citrullinated peptide (anti-CCP IgG), the two antibodies used to evaluate rheumatoid arthritis. RF is sensitive but not specific, since it also rises in other autoimmune conditions and chronic infections; anti-CCP is far more specific to RA and often appears years before symptoms or RF turns positive. When both are positive, the case for RA is strong, and anti-CCP positivity is linked to more aggressive, erosive joint disease. It is most useful when investigating persistent joint pain, morning stiffness, and symmetric swelling in the hands, wrists, or feet. If you want only the single most specific marker, the standalone anti-CCP test is the sharper one; this panel runs both for a fuller diagnostic read.
Biomarkers tested
Includes 2 biomarkers
- Specimen
- Serum or plasma
- Measures
- Concentration
Rheumatoid factor is an antibody that mistakenly attacks other antibodies, flagging the kind of immune misfire seen in rheumatoid arthritis and related autoimmune conditions. Elevated levels support investigation of joint pain, swelling, and stiffness, especially the symmetrical, morning-heavy pattern that distinguishes autoimmune arthritis from mechanical wear and tear. It's usually read alongside anti-CCP antibodies and inflammatory markers like CRP or ESR, since RF alone can turn up in healthy people or with other conditions and isn't definitive by itself.

Frequently asked questions
View all FAQsHow does pricing work?
Every test shows the member price next to the standard non-member price, so you can see what membership saves you. The member price is our cost, covering the lab and what it takes to run the service. It is never a profit on the test itself. Mito makes its money on the $9 membership, not on marking up your tests. Membership is $9 per month, and any applicable lab order or draw fee is itemized before you pay.
Where do I get tested?
Choose an available partner lab at checkout. If your cart contains multiple blood tests, Mito helps consolidate the eligible tests at one lab when possible. At-home kits and scans follow the collection or appointment process shown on their product page.
Is this eligible for HSA/FSA?
Yes. Eligible tests can be paid for with an HSA or FSA card at checkout.
When will I get my results?
Your results appear in your Mito dashboard after the laboratory completes processing. A clinician then reviews them before your analysis and personalized action plan are finalized. Timing varies by test, and specialty assays and at-home kits may take longer.
Do I need a physician's order?
No. Mito provides the laboratory order when one is required, so you do not need to arrange a separate physician visit before purchasing.
