What this test measures
What the NfL Blood Test measures
A biomarker associated with nerve cell injury
Neurofilament Light Chain, or NfL, is a protein that can be released into the blood when nerve cells are injured or damaged. Higher NfL levels may be associated with nerve cell injury, neurodegeneration, head injury, or other neurological changes.
Useful context, not a standalone answer
NfL is not specific to one condition. Results should be reviewed alongside your symptoms, medical history, and other clinical information with a qualified healthcare provider.
