Doctors have started using a skin test called Syn-One to help diagnosis Parkinson’s disease. It can detect a protein key to Parkinson’s called alpha synuclein in a few sharp pokes.

How can skin swabs help to spot Parkinson’s? Joy Milne, a “super smeller,” began noticing something strange when working as a nurse: she smelled something different on some of her patients.

But now, researchers have developed a new test that can diagnose Parkinson’s disease years before symptoms start.

A skin biopsy that can detect an abnormal protein in cutaneous nerve fibers holds promise for early detection of Parkinson's and other neurodegenerative disorders.

A simple blood test may help identify people at the earliest stages of Parkinson’s disease, long before they begin to show symptoms, new research has found.
