phosphoTAU ELISA

CE-IVD certified


Enzyme immunoassay for quantitative determination of Phospho-Tau in human CSF


3.5 h protocol, 25 µl CSF required

Intended use

The phosphoTAU ELISA is an enzyme immunoassay intended for the quantitative determination of phosphorylated tau in human cerebrospinal fluid (CSF) for supporting diagnosis of Alzheimer’s disease (AD). The development of Alzheimer’s disease is characterized by three stages, as defined by the US National Institute on Aging workgroups:

  • a preclinical stage of Alzheimer’s Disease,
  • the mild cognitive impairment (MCI) stage due to AD and
  • dementia stage due to AD.

Phosphorylated tau in CSF shows at least comparable diagnostic specificity and sensitivity to other diagnostic available tests for Alzheimer’s disease.
