Alzheimer's Risk Assessment Test
Alzheimer's Risk Assessment Test can be requested without a referral, and this overview covers what to expect. The Alzheimer's Risk Assessment Test is a blood panel that looks at selected proteins and genetic markers linked to brain health. It is ordered to help estimate risk or support evaluation when someone has memory concerns, but it cannot diagnose Alzheimer's disease on its own.

The Alzheimer's Risk Assessment Test is a blood panel that looks at selected proteins and genetic markers linked to brain health. It is ordered to help estimate risk or support evaluation when someone has memory concerns, but it cannot diagnose Alzheimer's disease on its own.
What it measures
- Apolipoprotein E (APOE) genotype — A gene variant that can affect risk; it does not predict whether someone will develop the disease.
- Amyloid-beta 42/40 ratio — A protein ratio that may reflect amyloid buildup in the brain.
- Phosphorylated tau (p-tau) — A protein that can rise when brain cells are stressed or damaged.
- Total tau — Another brain protein measured alongside p-tau for context.
- Neurofilament light (NfL) — A marker of general nerve cell injury, not specific to Alzheimer's.
Who it is for
It is typically ordered by a primary care clinician, neurologist, or memory clinic specialist, often after a cognitive screening or when someone reports memory changes.
Preparation
No fasting is usually required. Tell your clinician about any medications or supplements you take, and follow any timing instructions from the lab.
Results and what they mean
Results are reported as numeric values or genotype categories, and a clinician interprets them alongside your symptoms, age, and other tests. A higher or lower marker does not by itself confirm or rule out Alzheimer's disease. This is general information, not medical advice; discuss your results with a qualified clinician.
How to order this test
- Choose the test and place a confidential order online.
- Select a certified collection site and pick a time that suits you.
- Have your specimen collected — most draws take only a few minutes.
- Review results in a secure portal, typically within 1–3 days.
Preparation, hours, and pricing vary by site; confirm details directly with the lab before your visit.

Frequently asked questions
Can this test tell me if I will get Alzheimer's?
No. It estimates risk or supports evaluation, but it cannot predict with certainty whether you will develop the disease.
Do I need to fast?
Fasting is not usually required for this panel unless your clinician orders other tests at the same time.
Is the result private?
Yes. Your results are confidential and shared with you and the clinician who ordered the test.
What if my result is abnormal?
An abnormal value is a prompt for further discussion, not a diagnosis. Your clinician may recommend additional evaluation or monitoring.
