Term Description

The ratio of phosphorylated tau-181 (p-tau(181)) to beta-amyloid 42 (Abeta42). To report the ratio of total tau (t-tau) to Abeta42 in cerebral spinal fluid, use Tau protein/Amyloid beta 42 peptide [Ratio] in CSF [LOINC: 41027-4].

Part Description

LP157017-7   Tau protein.phosphorylated 181
Elevated levels of phosphorylated tau at threonine 181 (p-tau181) protein in CSF is associated with neurodegenerative processes and a candidate biomarker for Alzheimer's disease (AD). P-tau181 in CSF is thought to aid in the differential diagnosis of AD versus non-AD dementia, such as Lewy body disease. Source: Regenstrief LOINC, PMID: 19270764
