At a glance
Rheumatoid arthritis blood tests measure rheumatoid factor (RF), anti-CCP antibodies, and inflammation markers such as ESR and CRP, the lab signals most closely associated with autoimmune joint activity. They are designed for adults with symmetric joint pain, prolonged morning stiffness, or a family history of autoimmune disease who want objective data to review with their doctor. Four panel tiers range from a focused 3-test screen to a 10-test comprehensive workup covering 62 biomarkers.
Best suited for
- Adults with joint pain or swelling in the same joints on both sides of the body
- People whose morning stiffness regularly lasts more than thirty minutes
- Anyone with a family history of rheumatoid arthritis or other autoimmune conditions
- People already managing RA with their doctor who want labs to track markers between visits
- Adults whose joint symptoms have not been explained by imaging or a physical exam alone
What's included
Rheumatoid Arthritis - Basic
Rheumatoid Arthritis - Basic Plus
Rheumatoid Arthritis - Advanced
Rheumatoid Arthritis - Comprehensive
Deep-dive the key markers: hs-CRP
Key biomarker ranges
Commonly used adult reference ranges for markers this panel measures, labs vary, so always interpret results against your lab's stated ranges and with your doctor.
Commonly used cutoffs: under 1 mg/L low, 1–3 mg/L average, over 3 mg/L high; acute illness or injury can spike results, so retesting confirms a trend.
| Zone | Range |
|---|---|
| Low | 0–1 mg/L |
| Average | 1–3 mg/L |
| High | 3–10 mg/L |
The importance of testing
Rheumatoid arthritis-associated markers behave differently from general wear-and-tear signals. RF and anti-CCP are antibodies associated with the immune system targeting joint tissue, while ESR and CRP reflect how much active inflammation is present in the body. ANA screening adds a wider lens, flagging markers associated with autoimmune conditions that can affect more than just the joints. Measured together, these markers give your doctor far more to work with than symptoms alone.
Timing matters with autoimmune markers, because early information supports earlier conversations with your doctor about management. Marker levels also shift over time, so repeat testing is commonly used to track disease activity and see how markers respond as your doctor adjusts a care plan.
The four RA panel tiers let you match depth to your situation. The Basic panel covers 3 targeted markers; Basic Plus expands to 6 markers spanning inflammation, autoimmunity, and joint health; and the Advanced and Comprehensive tiers add 60-plus biomarkers of broad chemistry, blood counts, and organ function, useful context when medications and overall health are being monitored together. Whichever tier you start with, bring the results to your doctor, who can interpret them alongside your exam and history.

Order NowFrequently asked questions
Which blood tests are used for rheumatoid arthritis?
The core rheumatoid arthritis blood tests are rheumatoid factor (RF), anti-CCP antibodies, and the inflammation markers ESR and CRP, often alongside an ANA screen for broader autoimmune markers. These RA panels combine those markers in four tiers, from a 3-test Basic panel to a 10-test Comprehensive panel with 62 biomarkers.
Can I order RA blood tests without a doctor's visit?
Yes, these panels can be ordered online through the partner site without a separate doctor's appointment, with your sample collected at a local lab location. Results come to you directly and are designed to be reviewed with your own doctor.
Does a positive RF or anti-CCP result mean I have rheumatoid arthritis?
No, RF and anti-CCP are markers associated with rheumatoid arthritis, not a medical conclusion on their own. A doctor interprets these results together with your symptoms, physical exam, and imaging, since these markers can also appear in other conditions and occasionally in people without joint disease.
Which RA panel tier should I choose?
The Basic panel (3 tests) fits a first look at core autoimmune markers, while Basic Plus (6 tests) adds inflammation and joint-health markers. The Advanced (8 tests, 60 biomarkers) and Comprehensive (10 tests, 62 biomarkers) tiers add broad chemistry, blood-count, and organ-function biomarkers, useful when you and your doctor are monitoring therapy and overall health together.
Is RA blood testing available in every US state?
No, direct-to-consumer lab testing is restricted or prohibited in New York, New Jersey, and Rhode Island, so residents of those states may be blocked at the partner's checkout. Availability elsewhere depends on having a participating lab draw location nearby.
