Diagnostic Blood Test:

• Phosphorylated Tau 217 (pTau-217), Plasma

This test is NOT available to clients in New York (NY).

p-tau 217, Plasma measures the levels of phosphorylated tau protein at threonine 217 in the blood. Tau proteins are essential for stabilizing microtubules in neurons, and their abnormal phosphorylation is a hallmark of neurodegenerative diseases, particularly Alzheimer’s disease (AD). The p-tau 217 biomarker has emerged as a highly specific and sensitive indicator for the early detection and diagnosis of Alzheimer’s disease, offering significant advantages over traditional diagnostic methods.

This blood test helps in the biological identification of Alzheimer's disease.
