Why are blood biomarkers important in multiple sclerosis research? For years, MRI scans have been the main way to monitor MS activity, but they don’t always capture what’s happening. Researchers are studying blood biomarkers, like neurofilament light (NfL), which may better reflect nerve damage in real time. A simple blood test could one day help track disease activity, monitor treatment response and even detect progression earlier. While this approach is still evolving, it represents a major step toward more personalised and less invasive MS care.
