Alzheimer's Blood Testing
Early Clarity & Prevention
Our Alzheimer's Blood Testing, paired with Cognivue® Computerized Cognitive Assessment, helps catch cognitive issues early.
Alzheimer's: An Impending Risk for Americans
The number of people to develop Alzheimer's is projected to reach 12.7 million for people 65 or older by 2025. Luckily, there is a treatment to catch symptoms early and set a prevention plan. At the Stages of Life Institute, we now offer Alzheimer's Blood testing. This test can rule out chronic diseases and identify potential issues.
We also pair this blood testing with the Cognivue® Test, which helps our team decide which blood biomarkers to order. Note that our Alzheimer's blood test is a screening tool, not a diagnostic tool.
Accuracy At-A-Glance: About 80% Of Results Are Definitive
Roughly 20% fall into an “indeterminate” zone and should be confirmed with PET/CSF. A negative result can also point us away from Alzheimer’s and toward sleep disorders, mood issues, vascular problems, metabolic factors, or medication effects when the biology is not consistent with Alzheimer’s.
Dr. David S. Klein and the Stages of Life team combine these biomarkers with Cognivue® computerized cognitive assessment and a comprehensive clinical review to give you clear guidance, not just numbers and technical jargon.
What This Test Measures
Beta-amyloid (Aβ42/40 ratio). Amyloid proteins can form plaques in the brain. When plaque builds, Aβ42 falls relative to Aβ40 in the blood. Modern lab methods can quantify that ratio from a standard blood draw.
Phosphorylated tau (p-tau, notably p-tau217). Tau proteins form tangles inside brain cells in Alzheimer’s. When those processes begin, tiny phosphorylated fragments leak into the bloodstream; p-tau217 is among the most informative markers available today.
We Are Dedicated To Improving And Preserving A High Quality Of Life
Patients travel from all over the U.S. now have access to an Alzheimer's blood test that can arm them with insights about their cognitive health.
Earlier Clarity
You're not waiting months to get the answers and guidance you deserve.
Comfort In Nationwide Access
You can use any lab in the U.S. for the blood draw and have specimens shipped to Stages of Life for processing and physician-guided interpretation.
Earlier Access To Therapy
The sooner you know your risk is high, the sooner you an start focus on improving outcomes.
Empowered With Next Steps
If results are positive or indeterminate, a PET/CSF confirmation is necessary. If negative, we can target the real cause of your symptoms.
Monitoring & Prevention
For those at-risk genetically but who are cognitively intact, it's reassuring to screen, then confirm to optimize sleep, mood, cardiovascular risk, and lifestyle.
Secure In Their Privacy
For an additional $150, Dr. Klein can keep your report confidential and off insurance records (a private pay service so results aren't visible to insurers or employers).
Why Choose Stages Of Life For Your Cognivue® Test, Assessment, And Treatment?
Dr. David Klein has been practicing medicine since 1983, and is a pioneer in the fields of pain management and neuroendocrinology.
He pairs his medical experience and research insights with Cognivue’s computerized assessment with a review of your medical history, medication review, sleep and mood screening, and metabolic/vascular labs, most of which are done in his practice. You leave with clear next steps in plain language, what looks normal, what’s concerning, and treatment path he recommends.
If the pattern doesn’t fit Alzheimer’s, Dr. Klein redirects quickly to common, treatable causes, such as sleep disorders, depression/anxiety, vascular risk, metabolic issues, pain, or medication effects. He then treats what he finds.
He and his team are with you every step of the way in your journey, no matter where that journey takes you. We help arrange imaging, specialty referrals, and follow-ups, and we stay with you and your family as needs evolve.
Four Easy Steps To Identifying The Unknown
The process is simple and effective, and one of the easiest ways to gauge potential cognitive issues.

If you're not seeing Dr. Klein directly, we'll provide instructions for your local lab. Specimens are handled and shipped to Stages of Life for analysis and interpretation.
Results Review & Two-Step Pathway
You will get access to all available features immediately.
-
Likely positive: Discuss disease-modifying therapy options and arrange PET/CSF to confirm.
-
Negative: Pivot to non-Alzheimer’s causes and treatment.
-
Indeterminate: Repeat or escalate to confirmation testing.
Personalized Plan
This includes written recommendations covering sleep hygiene, mood support, pain management, cardiovascular risk reduction, exercise/nutrition, cognitive rehab, supplements (when evidence-supported), and follow-up intervals.
FAQ
Is this a diagnostic test for Alzheimer’s?
No. It’s a screening tool. It helps estimate whether Alzheimer’s biology is likely and whether to confirm with PET/CSF.
Do I need to come to your office for the blood draw?
No. You can use a local lab anywhere in the U.S. and have the sample shipped to Stages of Life with our instructions. We will guide you through the process.
How accurate is it?
Roughly 80% of tests yield clear positive/negative guidance. About 20% are indeterminate, which is the test being honest that biology is unclear—so we recheck or proceed to confirmation.
Will insurers or my employer see my results?
Not if you choose our $150 Privacy Service. We’ll keep your results confidential and off insurance records.
If not Alzheimer's, will I know if it's something else?
Yes. When results aren’t consistent with Alzheimer’s biology, we focus on sleep disorders, mood conditions, vascular risk, metabolic issues, pain, or medications—all common, treatable causes of cognitive symptoms.
How soon will I get results?
Turnaround varies by lab used and shipping, but most patients receive results within 1–2 weeks of their blood draw.
