Arthritis & Inflammation Tests
Below is a plain-language overview of the arthritis & inflammation tests. These tests help identify and monitor various types of arthritis and inflammation.
What this test is
Arthritis and inflammation tests are a group of laboratory analyses used to detect the presence of inflammatory conditions, particularly those affecting the joints. They can help differentiate between various types of arthritis and assess the level of inflammation in the body.
What it measures
- Rheumatoid Factor (RF) — an antibody often found in rheumatoid arthritis
- Anti-CCP Antibodies — antibodies associated with rheumatoid arthritis
- Erythrocyte Sedimentation Rate (ESR) — a measure of inflammation in the body
- C-Reactive Protein (CRP) — a protein produced by the liver in response to inflammation
- Antinuclear Antibodies (ANA) — antibodies that can indicate autoimmune conditions like lupus or rheumatoid arthritis
- Uric Acid — a marker for gout
What the test involves
A sample is typically collected through a standard blood draw from a vein in your arm. The collected blood is then sent to a laboratory for analysis.
Why it is often ordered
Clinicians often order these tests to investigate joint pain, stiffness, and swelling. They can also be used to monitor the effectiveness of treatment for inflammatory conditions.
Preparation
Follow any specific preparation instructions provided by the laboratory. This may include fasting or avoiding certain foods or medications before your sample collection.
How results are reported
Results are usually reported within a few business days and will indicate whether your levels are within the expected range. Reference ranges can vary between laboratories, so it is important to discuss your results with your healthcare provider.
Before you go
- Check fasting requirements
- Confirm collection site hours
- Verify identification needed
