What blood tests detect arthritis?

Common blood tests for rheumatoid arthritis include:

• Rheumatoid factor (RF)
• What it measures: Rheumatoid factor is a group of proteins your body makes when your immune system attacks healthy tissue.
• What's normal: 0-20 u/mL (units per milliliter of blood)
• What's high: 20 u/mL or higher.
