Plasma pTau blood biomarker tests (especially pTau217) for human clinical assessment of Alzheimer’s disease:

Dr. Carr currently offers the Labcorp pTau217 / amyloid beta 42/40 ratio and related Alzheimer’s blood biomarker testing as part of a robust dementia assessment or provides connections for testing through Apollo Health.

The Labcorp testing can be scheduled at their Patient Service Centers and has a good faith estimate of $398.40 for cash paying patients. Insurance billing is possible if the patient meets current guidelines for testing.
