Aquaporin 4 water channel Ab [Units/volume] in Serum or Plasma by Immunoassay

Active

Part Description

LP102618-8 Aquaporin 4 water channel Ab
Approximately 75% of patients with neuromyelitis optica (NMO) express antibodies to the aquaporin-4 (AQP4) receptor. Diagnosis of NMO requires the presence of longitudinally extensive acute myelitis (lesions extending over 3 or more vertebral segments) and optic neuritis. While absence of antibodies to the AQP4 receptor does not rule out the diagnosis of NMO, presence of this antibody is diagnostic for NMO. Source: ARUP Laboratories, ARUP

Basic Attributes

Class: SERO
Type: Laboratory
First Released: Version 2.34
Last Updated: Version 2.73 (MIN)
Change Reason: Release 2.67: COMPONENT: Updated "receptor" to "water channel" per current scientific nomenclature; Previous Releases: 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.
