A Positive Alzheimer’s Blood Test? Here’s What to Do Next.
This week, the FDA approved the first-ever blood-based test to detect Alzheimer’s disease: the Lumipulse G pTau217/ß-Amyloid 1-42 Plasma Ratio.
It’s a major milestone for early detection.
But what happens if that test comes back positive?
The truth is: a positive result is not a diagnosis.
The Lumipulse test detects amyloid plaques in the blood — a hallmark of Alzheimer’s — but it’s not definitive. It can’t rule out other causes of cognitive decline, nor can it confirm Alzheimer’s disease with complete certainty.
The FDA was clear: this blood test is not intended to be used alone, and it’s not a screening tool for the general population. It’s for individuals 55 and older who are already experiencing symptoms — and even then, results must be interpreted alongside other clinical data.
So what should you do next?
Step 1: Get Clarity.
DISCERN™ is the only test available today that can distinguish Alzheimer’s disease from other types of dementia while the patient is still alive.
It’s not just another “yes/no” test — it’s a diagnostic tool used by neurologists and memory care specialists to guide real treatment decisions.
Step 2: Act Sooner.
When it comes to neurodegenerative disease, every month matters. Early and accurate diagnosis means patients can start the right treatment sooner, plan more effectively, and access resources and clinical trials they may otherwise miss.
Step 3: Ask About DISCERN™.
- ✅ Over 95% sensitivity and specificity
- ✅ Fully covered by Medicare
- ✅ Ordered by specialists across the U.S.
- ✅ Used in conjunction with tools like BrainCheck to streamline access
If you or someone you love just received a positive result from the new Alzheimer’s blood test — don’t stop there.
Would you stop at a basic cancer screening?
