Autoimmune CNS Demyelinating Disease Reflexive Panel
Use
The Autoimmune CNS Demyelinating Disease Reflexive Panel is used in the initial evaluation of inflammatory central nervous system (CNS) demyelinating diseases, including acute disseminated encephalomyelitis (ADEM), neuromyelitis optica spectrum disorder (NMOSD), and myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD). Antibodies to aquaporin-4 (AQP4) and myelin oligodendrocyte glycoprotein (MOG) are screened, which are associated with demyelinating disorders. Detection of these antibodies can help in the diagnosis and management of these conditions.
Special Instructions
Not provided.
Limitations
This test is intended for clinical purposes and its performance characteristics were determined by ARUP Laboratories. It has not been cleared or approved by the US Food and Drug Administration. The presence of antibodies is diagnostic for NMO, but the absence of antibodies does not rule out a diagnosis of NMO or MOG-associated disorders. This test should be interpreted in conjunction with clinical findings and other laboratory data.
