Special Instructions

Minimum sample volume: 3 ml

Test Usage

Aquaporin 4 is the major autoantigen in neuromyelitis optica (NMO or Devic’s disease). Antibodies to AQP4 are found in >80% of NMO patients & around 50% of patients with longitudinally extensive transverse myelitis. They are infrequent in patients with optic neuritis without spinal cord involvement. Reviewed in: Jarius and Wildemann Nat Rev Neurol. 2010. Patients with AQP4 antibodies are at risk of relapsing, and immunosuppressive treatment is currently recommended before waiting for further events.
