Useful For Suggests clinical disorders or settings where the test may be helpful

Assessment of adults with cognitive impairment being evaluated for Alzheimer disease (AD) and other causes of cognitive impairment.

Highlights

Measurement of beta-amyloid (1-42)(Abeta42), total-Tau, and phosphorylated-Tau (p-Tau) in cerebrospinal fluid (CSF) is useful in the differential diagnosis of Alzheimer Disease (AD) and other causes of cognitive impairment.

 

These assays are being proposed as an alternative/adjunct to imaging studies to assess AD pathology.

 

The p-Tau/Abeta42 ratio provides excellent concordance with amyloid positron emission tomography (PET) scan to assess the presence of amyloid deposition in patients with AD.
