What blood test shows stiff person syndrome?

There is no specific blood test that can diagnose Stiff Person Syndrome. However, a definitive diagnosis can be made with a blood test that measures the level of glutamic acid decarboxylase (GAD) antibodies.

Most people with SPS have elevated (higher) levels of GAD antibodies. This condition is a rare neurological disorder that affects the muscles, causing them to become stiff and difficult to move.

In order to diagnose Stiff Person Syndrome, a healthcare provider will typically conduct a physical examination and review the individual’s medical history.

They may also order a series of tests, such as blood tests, imaging scans, and electrodiagnostic tests, to help confirm the diagnosis.

Blood tests may be ordered to check for certain markers of autoimmune activity, such as elevated levels of antibodies, but there is no specific blood test that can diagnose Stiff Person Syndrome.

It is important for individuals who are experiencing symptoms of Stiff Person Syndrome to speak with their healthcare provider to determine the best course of action.
