UCLA researchers develop blood test to detect ALS earlier using cell-free DNA

ALS patients face rapid disease progression with 2-5 year life expectancy after diagnosis, making early detection potentially life-extending.

In the long struggle against amyotrophic lateral sclerosis — a disease that has offered patients little more than a swift and certain decline — researchers at UCLA Health have found a quiet signal in the bloodstream that may speak before the disease fully declares itself. By reading the chemical signatures of dying cells through a simple blood draw and training machines to recognize their patterns, the team has opened a path toward earlier diagnosis, where every month recovered from delay is a month returned to living. The work, still in its early stages, asks a question medicine has long been
