P217 TAU results

Posted by dig2dye2 @dig2dye2, Sep 10 6:40pm

My HWD has RBD and MCI. We got a great team that we met with and they ran the p217 TAU test through MAYO labs.

His result was 0.270 Intermediate…

Not sure what that means?

Interested in more discussions like this? Go to the Caregivers: Mild Cognitive Impairment (MCI) & Dementia Support Group.

Not sure either. Send a note from her husband's portal to the doctor and ask them to explain. That way you have it in writing in hopefully, terms you can understand.
Best, Karla

What is considered a high level of p Tau217?
AI Overview
A high level of plasma p-tau217 is generally defined as a concentration at or above 0.32 to 0.33 pg/mL on widely used clinical testing platforms like Lumipulse.

Typical Assay Reference Ranges
Reference ranges vary depending on the specific laboratory and testing method used. A common two-cutoff approach divides results into three categories:

HealthMatters.io
Negative (Low Level): ≤ 0.18 to 0.20 pg/mL. This suggests Alzheimer's-type amyloid pathology is unlikely.
Indeterminate / Gray Zone: 0.18 to 0.32 pg/mL. This is a borderline result that often requires repeat testing or further clinical evaluation.
Positive (High Level): ≥ 0.32 to 0.33 pg/mL. This indicates that Alzheimer's-type amyloid and tau pathology in the brain is likely.
