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

Change Reason
The EIA method, which was always intended to cover more than just enzyme-linked immunoassay and whose display name for the long common name has always been Immunoassay, was renamed IA in order to eliminate ambiguity about whether the method has a broader meaning than just enzyme-linked immunoassay. Likewise, EIA.rapid was renamed IA.rapid. These changes were approved by the Laboratory LOINC Committee in June 2016.
