Clinical Use
Order TestUse
Antibody to Aquaporin‑4 is associated with neuromyelitis optica (NMO), a demyelinating disease of the central nervous system that may resemble multiple sclerosis or transverse myelitis. Differentiating NMO from MS early is clinically important, as optimal treatment approaches differ significantly and early detection can guide appropriate therapy.
