What this test measures
Neurofilament Light Chain, explained simply
A biomarker associated with nerve cell injury
Neurofilament Light Chain (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.
Insight, not a diagnosis
NfL is not specific to any one condition. Results should be reviewed alongside symptoms, medical history, and other clinical information with a qualified healthcare provider.

Important medical note
NfL is not specific to any one condition and should not be used by itself to diagnose Alzheimer's disease, ALS, MS, Parkinson's disease, dementia, traumatic brain injury, or any other condition. Results should be reviewed alongside your symptoms, medical history, and other clinical information with a qualified healthcare provider.
