Arthritis Tests: RF, Anti-CCP, ESR and CRP Explained

The pain of waking up with tight joints does not have to indicate that you're only older; ongoing Joint Swelling and Pain require specific diagnosis outlined below. No one test gives a 'yes/no' answer, one will provide a combination of several Markers and Imaging to build your Physician's evaluation of your Joint Health status.

The Challenge of Diagnosing Rheumatoid Arthritis

Because there are many conditions that could cause joint stiffness and inflammation, and no single definitive test used to diagnose rheumatoid arthritis, the diagnosis of RA can be complicated. This is further complicated by the fact that the symptoms of rheumatoid arthritis are often very similar to, or identical to, those of other types of arthritis and other autoimmune diseases.

When you see a GP, they will perform a physical examination to see if there is swelling in the joints and to determine how well they can move through their range of motion. You need to inform your GP about all of the symptoms you are experiencing, including any minor symptoms, to allow them to determine if you will need a referral to a rheumatologist for further evaluation.

Understanding Inflammation Markers: ESR and CRP in Blood Test

The evaluation of your immune system is first and foremost based on markers of systemic inflammatory activity via Crp in blood test.

• Erythrocyte sedimentation rate (ESR): This measure indicates how quickly red blood cells fall to the bottom of a tube; once again, the quicker the fall, the greater the degree of inflammation in the body.

• C-reactive protein (CRP): It is a common blood test used to measure levels of acute inflammatory activity; similarly, increased levels of CRP are indicative of an increase in liver production caused by inflammatory stimuli.

Since inflammation can vary with time, measuring the values of ESR and CRP allows physicians to observe changes in their patient's condition. Individuals suffering from chronic symptoms will have their CRP checked regularly and receive ongoing treatment based on the CRP value. 

Specific Antibodies: Rheumatoid Factor (RF) and Anti-CCP

Even though ESR and CRP (C-reactive protein) tests provide general information about level of inflammation in the body, both tests use markers that represent different aspects of being attacked by the immune system and produce higher levels of protein than healthy individuals.

1. Rheumatoid Factor Test (RF): RFs are proteins released by the body’s immune system during an attack on joints/tissue. More than 50% of people diagnosed as having RA have a positive RF at the beginning of their disease. However, just because someone tests positive for RF does not mean that they have RA (in fact, 1 in 20 people who do not have rheumatoid arthritis will also test positive for RF.)

2. Anti-CCP Antibody Test(AT-CCPs): This is a more targeted test than a rheumatoid factor. If you have been diagnosed with an autoimmune disease and have tested positive for the AT-CCP test, it may mean that you have RA.

3. Combined Factors: Patients testing positive to both RF and the ATCCP test may be at increased risk for severe rheumatoid arthritis and require a more robust treatment regime based on dual positive results.
