How to check your Rheumatoid Factor levels with a home finger-prick 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.

What If Rheumatoid Factor Test Levels Are High?

What If Rheumatoid Factor Test Levels Are High?

A high Rheumatoid factor can be caused by other autoimmune and infectious diseases, so alone is not a diagnosis of rheumatoid arthritis.

While it does make it much more likely that you have arthritis, this should be reviewed alongside a complete knowledge of your clinical history and medical status.

Please follow up with your GP to ensure a diagnosis can be made.
