The diagnostic tracks a particular kind of protein—known as neurofilament light chain, or NfL—as found in the bloodstream. Originally produced inside the brain’s neurons, it can be released into the body in higher-than-normal amounts when those cells come under strain.

“Importantly, NfL isn’t specific to one disease, but it is highly specific to neuronal damage from a wide variety of causes, from Alzheimer’s and multiple sclerosis to concussion and physical injury,” Labcorp’s neurology business segment director, Joseph Volpe, said in a statement.
