LaboratoryPhosphorylated tau 181/Amyloid beta 42 peptide [Ratio] in Cerebral spinal fluid
Definition
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].
