Blood Matters


A guide to the blood tests used in managing rheumatoid arthritis and adult juvenile idiopathic arthritis.

Blood tests are an important part of both the diagnosis and monitoring of rheumatoid arthritis (RA), and juvenile idiopathic arthritis (JIA), but the different tests, abbreviations and numbers can be confusing, and it might not always be clear to you what the purpose of each test is, why it’s important and what the results mean.

We have created this resource because we strongly believe that having a good understanding of your blood tests is important to help you to manage your condition and improve outcomes.
