I had a clinically available test done called the Syn-One skin biopsy test in 2023 and then 2.5 years later in 2026. My neurologist (albeit reluctantly) ordered it at my request. Even though I received abnormal results, I’m very glad I had the test done now while I am in my forties. The test has not been around long enough or tested in young enough people to be predictive for someone without diagnostic symptoms. But if we don’t test people in early potential stages, we will never know. This test also confirmed that I have small fiber neuropathy. I have very painful peripheral neuropathy symptoms.
