At BetterBrain, the pTau-217 blood test is $299. It is offered as an add-on to a Blueprint assessment, not sold on its own, and it is always paid out of pocket since it is not covered by insurance. pTau-217 is a blood-based marker associated with Alzheimer's disease pathology, and it requires an in-lab blood draw.
pTau-217, or phosphorylated tau 217, is a protein measured in your blood. Elevated levels are associated with the biological changes of Alzheimer's disease, and research shows the marker can reflect these changes years before symptoms appear. A pTau-217 result is not a diagnosis. It is one input that you and your clinician can use to understand your risk and act early.
At BetterBrain, pTau-217 testing is available as an add-on to a Blueprint assessment. It is not sold as a standalone test, because a single marker is most useful in the context of your broader brain health picture: your 50+ blood biomarkers, your cognitive evaluation, and an up to 90-minute session with a Brain Health Coach who walks you through every result. The test requires an in-lab blood draw at a Quest Diagnostics location.
pTau-217 testing is currently not available in NY, NJ, or RI. Everywhere else in the US, you can add it to your Blueprint assessment at checkout.
No. The pTau-217 add-on is always paid out of pocket and costs $299 on top of your Blueprint assessment, which is $89 with insurance or $399 cash pay.
