Fluorescence Activated Cell Sorting (FACS) Assay
Establishing the diagnosis of neuromyelitis optica (NMO) and related disorders (e.g., relapsing transverse myelitis or relapsing optic neuritis) and distinguishing these disorders from multiple sclerosis early in the course of the disease.
* Reference ranges may change over time. Please refer to the original patient report when evaluating results.
A negative result does not exclude a diagnosis of neuromyelitis optica spectrum disorder (NMOSD). Serum is generally more sensitive than cerebrospinal fluid for detection of neuromyelitis optica (NMO)/aquaporin-4(AQP4)-IgG (NMO-IgG/AQP4-IgG.

Collect CSF specimen and refrigerate. Include relevant clinical information as well as ordering physician name, telephone number, and mailing address.
If results require further evaluation, Neuromyelitis Optica (NMO) / Aquaporin-4-IgG, CSF, Titer will be performed at an additional charge.
