Rheumatoid Factor (RF) Testing
How to check your Rheumatoid Factor levels with a home fingerprick blood test kit
What Is A Rheumatoid Factor Test For?
Rheumatoid factor (RF) is a protein naturally present in your blood. It is made by your immune system, but can mistakenly identify your own tissue as "foreign" and cause an attack on your own body.
80% of people with rheumatoid arthritis will have elevated RF levels. So rheumatoid factor (RF) testing is a useful tool to help identify the presence of this autoimmune condition.
