SelectedRheumatology Profile 6 (Rheumatoid Plus) is a targeted blood test panel designed to assess rheumatoid arthritis and inflammatory joint disease. It combines autoantibodies and an inflammatory marker to improve diagnostic accuracy.
This profile includes:
Rheumatoid Factor (RF)
Anti-CCP (Cyclic Citrullinated Peptide) Antibodies
C-Reactive Protein (CRP)
RF and anti-CCP antibodies help identify autoimmune-driven joint inflammation, while CRP reflects the level of active systemic inflammation. Together, these markers provide a more comprehensive assessment than RF testing alone.
Inflammatory arthritis can cause permanent joint damage if not identified and managed early. This profile helps distinguish autoimmune inflammatory arthritis from non-inflammatory joint pain.
It is especially useful when symptoms are persistent, progressive, or when early rheumatoid arthritis is suspected but diagnosis is uncertain.
You may benefit from this test if you experience:
Persistent joint pain or swelling
Morning stiffness lasting longer than 60 minutes
Symmetrical joint symptoms (hands, wrists, feet)
Fatigue or unexplained inflammation
Family history of rheumatoid arthritis
Suspected early inflammatory arthritis
Monitoring known rheumatoid disease
Unclear cause of joint pain
Improves rheumatoid arthritis detection
Anti-CCP antibodies increase diagnostic specificity.
Identifies autoimmune joint inflammation
RF and anti-CCP reflect immune-driven disease.
Assesses active inflammation
CRP indicates current inflammatory activity.
Supports early diagnosis
Early detection helps prevent joint damage.
Differentiates inflammatory vs mechanical pain
Helps clarify cause of joint symptoms.
Useful in seronegative evaluation
Anti-CCP may be positive when RF is negative.
Supports treatment planning
Inflammation level guides clinical decisions.
Simple, targeted rheumatology panel
Focused testing with high clinical value.

Normal results suggest no detectable autoimmune joint antibodies or active inflammation at the time of testing. This makes active rheumatoid arthritis less likely, though early disease cannot be fully excluded.
Clinical symptoms remain important.
UK reference interpretation:
RF: Negative
Anti-CCP: Negative
CRP: Within reference range
Positive RF or anti-CCP with normal CRP may indicate early or inactive autoimmune arthritis. Anti-CCP positivity is particularly specific for rheumatoid arthritis, even before inflammation becomes clinically apparent.
Monitoring and specialist input may be advised.
UK reference interpretation:
RF and/or Anti-CCP: Positive
CRP: Normal
Positive RF or anti-CCP combined with elevated CRP suggests active autoimmune inflammatory arthritis. This pattern is strongly associated with active rheumatoid arthritis and may reflect disease severity.
Prompt rheumatology assessment is often recommended.
UK reference interpretation:
RF and/or Anti-CCP: Positive
CRP: Elevated

Where possible, attend your blood test between 7am and 12pm. Please wait until any short-term illness or infection has fully resolved before testing. Avoid intense exercise for 24–48 hours beforehand, as this can affect certain markers.
Fasting is not always required, but some tests may recommend it. If fasting is advised, avoid food for 8–12 hours before your appointment and drink water only. Stay well hydrated, as this helps with sample collection and accuracy.
Continue prescribed medications unless advised otherwise by your clinician. Avoid vitamin, mineral, or biotin supplements for at least 24–48 hours before your test, as these can interfere with results. If you are unsure about any medication or supplement, please let us know before your appointment.
For hormone-related tests, timing within your menstrual cycle may be important. If relevant, follow any specific guidance provided on your test page.
If you have any questions or special circumstances, our team is happy to advise before your appointment.
