Osteoarthritis elbow: Biological tests

Some biological tests may be requested by your doctor to confirm the diagnosis of osteoarthritis.

These are:

• blood tests,
• synovial fluid tests,
• histological examinations.

There are no specific biological signs of osteoarthritis.

For several years, some research teams have been looking for products of the metabolism of articular cartilage (found in synovial fluid, urine or blood of people with osteoarthritis), which could be biological indicators of osteoarthritis. Currently, research has not yet been completed, but the findings are promising.
