A major breakthrough
in brain health
pTau 217 is a new blood test that helps clinicians understand one of the strongest biological signals associated with Alzheimer's disease. Everlab is the first preventative healthcare service in Australia to offer it to eligible members.

Dr Steven Lu, Chief Medical Officer, on what pTau 217 means for our members.
Why pTau 217 matters
For decades, understanding whether someone may be developing Alzheimer's disease has often relied on specialised brain imaging or invasive procedures. pTau 217 represents a significant step forward, giving clinicians a simpler way to understand one of the strongest biological signals associated with Alzheimer's disease using a blood test.
While no single test can diagnose Alzheimer's disease on its own, pTau 217 adds an important new tool to help clinicians build a clearer picture of brain health.
Why Everlab
is offering it
Everlab exists to bring clinically meaningful advances in preventative medicine to our members as early as possible. That's why we're proud to be the first preventative healthcare service in Australia to offer pTau 217 to eligible members.
We continually evaluate emerging diagnostics with strong clinical evidence, making important advances available when they can meaningfully improve care.
From booking to results.
pTau 217 testing is available now.
Access the pTau 217 test in the Everlab app.
Frequently asked questions
What is pTau 217?
pTau 217 is a protein measurable in the blood that reflects one of the strongest known blood-based biomarkers associated with Alzheimer's disease pathology. A pTau 217 blood test measures the level of this protein as part of a broader clinical picture of brain health, alongside other diagnostic tools your doctor may use.
Does a positive pTau 217 result mean I have Alzheimer's disease?
No. pTau 217 is one important biological signal, not a standalone diagnosis. No single test, blood-based or otherwise, can diagnose Alzheimer's disease on its own. The results of the test need to be interpreted together in your personalised context, such as your broader medical history, any symptoms, and other risk factors to help guide further diagnostic or prevention action.
How is a pTau 217 blood test different from a PET scan or spinal tap?
Amyloid PET and tau PET brain imaging, and lumbar puncture to test cerebrospinal fluid, have traditionally been the main routine laboratory tests and diagnostic tools used to understand this kind of Alzheimer's-related biological signal. Both are more invasive and less accessible than a blood draw. pTau 217 testing brings a similar kind of insight into a standard, doctor-reviewed blood test.
Who is the pTau 217 blood test for?
The pTau 217 blood test is available for members aged 55 and over.
How do I find out if I'm eligible for pTau 217 testing?
An Everlab doctor reviews your eligibility before your sample is taken, and if you're not eligible, you're refunded in full.
What happens after I pay?
You'll be asked to complete a dedicated questionnaire, including the Cognitive Function Instrument, a standardised check-in that gives you and your doctor a baseline read on your cognitive function alongside your test result. An Everlab doctor reviews your questionnaire. If eligible, they'll order the test; if not, you'll be refunded in full.
