Top ALS Biomarkers: Testing and Progress
ALS biomarkers are measurable signals in blood, cerebrospinal fluid, urine, imaging, or nerve tests that can help diagnose amyotrophic lateral sclerosis sooner, predict disease progression, and evaluate whether treatments are working. This guide explains the most studied ALS biomarkers—especially neurofilament light (NfL)—and why reliable biomarkers could reduce diagnostic delays and improve personalized ALS care. It also highlights emerging research such as multi-protein panels, genetic and “omics” approaches, and digital biomarkers from wearables that may transform early detection and clinical trials. While challenges remain around specificity, access, cost, and standardization, global ALS research hubs are accelerating progress toward practical biomarker testing. als.COMMUNITY is a free, one-stop platform for everyone impacted by ALS.
