Sunbird Bio blood test may yield accurate Parkinson’s diagnosis

Sunbird Bio has developed a blood test that may help accurately diagnose Parkinson’s disease by detecting toxic clumps of the protein alpha-synuclein, which is associated with the disease. This test, uses a proprietary technology to identify alpha-synuclein bound to brain-derived extracellular vesicles (EVs) in the blood, offering a potential diagnostic tool for Parkinson’s and other neurological disorders. Parkinson’s involves the accumulation of misfolded alpha-synuclein proteins that form toxic structures in the brain, leading to nerve cell damage and motor symptoms. Currently, Parkinson’s is diagnosed based on symptoms, medical history, and physical exams, as there are no blood-based tests for diagnosis. Sunbird Bio’s test demonstrated 86% accuracy in distinguishing people with Parkinson’s from healthy individuals by measuring EV-bound alpha-synuclein in blood. This approach could also be valuable for diagnosing other diseases marked by protein clumps, such as Alzheimer’s.
