hTAU total ELISA (CE)
Learn how to use this product The hTAU total ELISA is an enzyme immunoassay intended for the quantitative determination of total tau protein in human CSF for supporting diagnosis of Alzheimer’s disease (AD). The development of the Alzheimer’s disease is characterized by three stages, as defined by the US National Institute on Aging workgroups:
1. a preclinical stage of Alzheimer’s Disease,
2. the mild cognitive impairment (MCI) stage due to AD and
3. dementia stage due to AD.
Tau shows at least comparable diagnostic specificity and sensitivity to other diagnostic available tests for Alzheimer’s disease.
