Parkinson’s breakthrough can diagnose disease from skin swabs in 3 minutes
Researchers at the University of Manchester used cotton swabs to take sebum samples from the skin of participants which were then analysed via mass spectrometry.

To summarise, it is been known for sometime that the body odour of people with Parkinson's Disease is quite distinct due to the altered way in which their sebum (the skin's oily secretions) is produced. This means that sebum in these patients is a useful biomarker for Parkinson's. By using mass spectrometry - a method used to calculate exact molecular weight - lipids that are found in the sebum of people with Parkinson's can be pinpointed (because we know they have particularly high molecular weight). What is more, the technique developed by the team is both non-invasive and rapid.
By developing novel techniques for identifying biomarkers, diagnostic processes can be made more exact and more efficient, which means that treatment can be started earlier and with more success.
As this article in The Conversation explains - Parkinson’s disease: treatment is best started early - the sooner Parkinson's treatment can be commenced the better. Although there is currently no cure, there are treatments available to manage and control the symptoms.
