How much does a pTau-217 test cost?
$299, added to a Blueprint assessment at checkout. pTau-217 is a blood marker linked to Alzheimer's-related changes in the brain, which can show up years before symptoms. We only run it alongside Blueprint, so your result arrives with the context to make sense of it.

For pTau-217. Your coach session happens once every result is in.
What a result can and can't tell you
It can show
- Whether Alzheimer's-related changes, like amyloid plaque buildup, may already be underway.
- Changes that can appear years before any symptoms, while there is still time to act on the risk factors around them.
- One clear input for a conversation with your clinician about your risk.
It can't tell you
- That you have Alzheimer's. An elevated result is a signal, not a diagnosis.
- Whether, or when, symptoms will develop.
- What to do on its own. pTau-217 is a measurement, not something one intervention lowers. The action is in the rest of your picture.

What happens after the test
Whatever your pTau-217 result, you leave with a plan, not just a number. BetterBrain's science-backed prevention program turns your results into specific steps, then helps you follow through.
- THE SESSION
Your results, explained
Up to 90 minutes 1:1 with your Brain Health Coach, a licensed clinician trained in dementia prevention. They read your pTau-217 result alongside your 50+ biomarkers and cognitive results, and explain what it indicates and what it doesn't.
- THE PLAN
A plan ranked by impact
A personalized action plan across sleep, nutrition, exercise, stress and cardiovascular health, matched to your biology, so you know what to do first and what will make the biggest difference.
- THE ACCOUNT
Support between sessions
Lifetime access to the BetterBrain account: your Brain Score, biomarker trends and action plan, our research library, BetterBrain Picks, and BeBe, our AI brain health coach, available 24/7.
- THE FOLLOW-UP
Retest and track progress
Most clients retest around the 90-day mark. Among clients who retest, 88% of tracked brain-related biomarkers have moved in a positive direction within 90 days. Ongoing Coaching is available if you want up to weekly support.
One marker is a clue. The full panel is the picture.
Blueprint covers 50+ blood biomarkers, a cognitive assessment, and an up to 90-minute 1:1 with a Brain Health Coach. Your pTau-217 result gets read alongside all of it, including the metabolic, vascular and inflammation markers you can act on.
of dementia cases are potentially preventable by addressing modifiable risk factors, according to the 2024 Lancet Commission. Blueprint shows you which of those factors apply to you.

That's a fair question, and a common one. A pTau-217 result can be hard to sit with, especially if you're managing anxiety or depression. It's one reason we don't offer it on its own. You can talk it through with us before you decide.

We believe that providing pTau-217 testing without proper support and guidance is ethically problematic. Learning about your dementia risk can be emotionally challenging, and we want to ensure you have the resources and context needed to process this information. Our comprehensive program offers not just testing, but also personalized prevention strategies, expert consultation, and ongoing support, giving you both clarity about your risk factors and actionable steps to improve your brain health. This integrated approach ensures you're never left wondering "what's next?" after receiving your results.
Does insurance cover pTau-217?
No. The $299 add-on is always paid out of pocket, even when insurance covers your Blueprint assessment.
How long do results take?
Most of your Blueprint panel comes back in about three business days. pTau-217 takes about two weeks. Your coach session happens once every result is in, so you go through all of it together, in one sitting.
What does an elevated result mean?
It suggests Alzheimer's-related changes may be present and that your risk is higher. It is a signal, not a diagnosis. Your coach walks you through it, and it is worth taking to your clinician.
Where is it available?
Everywhere in the US except New York, New Jersey and Rhode Island.
