pTau test details

A pTau test is a simple blood test that screens for levels of the pTau protein. In healthy brains, tau proteins help nerve cells work properly. When tau becomes “phosphorylated,” it means a small chemical tag attaches to the protein and changes how it works, which can cause it to build up in harmful ways. Higher levels of pTau can damage nerve cells and affect memory and thinking. Even if someone has higher levels of pTau, this is not an Alzheimer’s disease diagnosis.

This test checks for higher levels of pTau so you can talk with your doctor about next steps, including further testing or possible early interventions.

Simple and easy - great to know my levels were normal and at the same time helping to assist in the research process. I’d participate in any Care Access study in the future. Very impressed by your professional and friendly staff too!
