Weekly

Test Overview

This test is used to assist with ascertaining the cause of neurological impairment, in the context of Alzheimer's disease pathology, by measuring phosphorylated tau 217, which acts as a surrogate marker of amyloid pathology. Additionally, the test can be used for monitoring patients on newly approved anti-amyloid therapy. The methodology (SIMOA) offers increased sensitivity compared to other methods, and is able to detect very small amounts of the biomarker.
