Notes
A positive pTau181/Abeta42 or tTau/Abeta42 ratio result in CSF does not establish a diagnosis of Alzheimer’s disease (AD) and should always be interpreted in conjunction with clinical information.
The performance of the test for African-American, Asian, and other races had high uncertainty due to the limited number of patients studied.
