You’re Not Imagining It. You Just Might Need Data.
If you’re noticing changes in your memory, focus, or thinking—or have a family history of Alzheimer’s, MS, or ALS—this test can help detect early signs of brain cell damage.
The Neurofilament Light Chain blood test (also known as the NfL test) measures a specific protein released when neurons are injured. Elevated levels can indicate neurodegeneration, even before symptoms become severe.
Most people never get access to this kind of data until it’s too late—because traditional healthcare makes it difficult. Between insurance red tape, delayed referrals, and confusing billing, many people are left waiting and wondering.
