A new test is making headlines—but is it really the game-changer we’ve been waiting for?
If you’re caring for someone with dementia, chances are you’ve seen the buzz: a new Alzheimer’s blood test is now available to the public. And while the news feels hopeful, it also raises a lot of questions:
- Can a blood test really diagnose Alzheimer’s?
- Should we get tested?
- Will this change how we care for our person with dementia?
Let’s break it down—honestly, clearly, and with the caregiver in mind.
💉 What is the Alzheimer’s blood test?
This new blood test—known as PrecivityAD2—is designed to detect biomarkers (proteins) associated with Alzheimer’s disease, like amyloid-beta and tau. These are the same markers doctors traditionally look for using expensive PET scans or lumbar punctures.
The test is currently available by prescription through a doctor and is intended for adults over 50 with signs of cognitive decline.
🔍 Is it accurate?
Studies show the blood test is over 90% accurate in predicting Alzheimer’s-related brain changes. That’s a big deal, especially for people in early stages or those still searching for answers.
But let’s be real:
- It’s not a final diagnosis
- It doesn’t predict how fast the disease will progress
- And it won’t tell you what kind of support your person actually needs day-to-day
đź’° Is it covered by insurance?
As of now, no, not yet. The test costs around $400–$1,250, depending on your provider and the lab. Some Medicare Advantage or private plans may reimburse it, but there’s no universal coverage yet.
TLDR: Talk to your doctor and your insurance rep before moving forward.
🧠What does this mean for caregivers?
Here’s the truth: this test could help families get answers sooner, and that’s powerful. An early, accurate diagnosis can mean:
- Planning ahead while your person can still express their wishes
- More time to learn about what to expect
- Access to treatments (like Leqembi) for those who qualify
- Peace of mind from simply knowing what’s happening
But it won’t stop the disease. And it doesn’t replace the need for real-life support, training, and community—which is where you and I keep showing up.
đź’¬ My take as a dementia expert and caregiver educator:
I’m hopeful.
I’m also cautious.
Caregivers already have enough pressure on their backs—and while testing may give some clarity, it shouldn’t be another thing we feel forced into.
This test may change the future of diagnosis, but you are still the expert on your person.
And no matter what the results say, they’ll still need love, connection, and care rooted in dignity.
