CertuitAD: a blood test that helps test for Alzheimer’s disease (AD) pathology1

What is CertuitAD?

CertuitAD is a blood test that measures P-tau2171.

What is P-tau217?

P-tau217, a soluble fragment of tau, is a biomarker associated with Alzheimer’s disease (AD) pathology.2,3

Who is the appropriate patient?

CertuitAD is intended to be used in patients aged 60 years and older who present with cognitive impairment and who are being evaluated for Alzheimer's disease (AD) and other causes of cognitive decline.1

CertuitAD results must be interpreted in the setting of a thorough clinical evaluation. CertuitAD is not intended to be used as a screening or stand-alone diagnostic test and is not intended for therapeutic monitoring. A positive result by itself does not establish a diagnosis of AD. Additional laboratory testing (such as APOE genotyping) may be warranted based on the patient’s clinical presentation and/or family history.1
