ABETA 42/40 RATIO

The Aβ42/40 Ratio (Amyloid Beta 42/40 Ratio) is a biomarker that helps detect early signs of Alzheimer’s disease by measuring the balance between two key amyloid beta proteins in the blood or cerebrospinal fluid. A lower ratio indicates a

Neurofilament Light Chain (NfL)

Serum

Neurofilament proteins are vital structural components of nerve cells, helping to maintain their shape and function. Of these, neurofilament light chain (NfL) has emerged as a clinically important biomarker. When neurons are damaged or unde

Quest AD-Detect® Phosphorylated tau217 (p-tau217), Plasma

Plasma

This test measures levels of phosphorylated tau217 (p-tau217) in the blood—a protein strongly linked to the development of Alzheimer’s disease and other neurodegenerative conditions. Tau proteins normally help stabilize nerve cells in the
