Tests and diagnosis
By Mayo Clinic staff
To diagnose de Quervain's tenosynovitis, your doctor likely will confirm that you have both:
- Tenderness when pressure is applied on the thumb side of the wrist
- Positive results on a Finkelstein test
In a Finkelstein test, you bend your thumb across the palm of your hand and bend your fingers down over your thumb. Then you bend your wrist toward your little finger. If this causes pain on the thumb side of your wrist, the test is considered positive.
