Anti-Aquaporin-4 (NMO-IgG) Antibodies are autoantibodies targeting the aquaporin-4 protein, which is primarily found in the central nervous system, particularly in the optic nerves and spinal cord.
Testing for Aquaporin-4 antibodies is crucial for diagnosing Neuromyelitis Optica Spectrum Disorder (NMOSD), a rare autoimmune condition often misdiagnosed as multiple sclerosis due to overlapping symptoms.
Aquaporin-4 (AQP4) is a protein channel in the cell membranes of the central nervous system, facilitating the movement of water molecules. In people with NMOSD, the immune system produces antibodies, specifically Anti-Aquaporin-4 antibodies (NMO-IgG), against this protein, leading to inflammation and damage in the optic nerves and spinal cord.
Early and Accurate Diagnosis of NMOSD: Identifying Aquaporin-4 antibodies helps differentiate NMOSD from other demyelinating disorders like multiple sclerosis, enabling more targeted treatment.
Guiding Treatment and Management: An Aquaporin-4 antibody positive result confirms NMOSD, allowing physicians to prescribe immunosuppressive treatments to reduce relapses and prevent disability.
Monitoring Disease Progression: Regular testing can help monitor disease activity, especially in individuals with fluctuating symptoms or those in remission.
Results for the Anti-Aquaporin-4 antibody test are typically categorized as positive or negative:
Aquaporin-4 antibody negative: Indicates an absence of NMOSD-specific antibodies in the blood, although it does not rule out NMOSD entirely. Some patients may have NMOSD without detectable levels of AQP4 antibodies.
Aquaporin-4 antibody positive: Confirms the presence of NMOSD and suggests a higher risk of recurring attacks, often leading to more aggressive treatment approaches.
The Anti-Aquaporin-4 antibody test is recommended for:
Individuals showing symptoms of NMOSD, such as sudden vision loss, painful eye movement, or persistent numbness/weakness in the limbs Patients with a prior diagnosis of multiple sclerosis but presenting with atypical symptoms Individuals experiencing recurrent episodes of myelitis (spinal cord inflammation) or optic neuritis.

A positive result suggests a risk for NMOSD, a potentially disabling disorder. Early treatment can help manage symptoms and prevent severe complications.
Individuals experiencing symptoms like optic neuritis or myelitis, or those with an atypical presentation of multiple sclerosis, should consider this test.
A positive Aquaporin-4 antibody result confirms NMOSD, indicating an increased risk of recurrent attacks affecting the optic nerves and spinal cord.
This test is done through a blood sample analysis, with results showing the presence or absence of AQP4 antibodies.
Yes, while Aquaporin-4 antibodies are present in most cases, some individuals may have NMOSD without detectable levels of these antibodies.
The Aquaporin-4 antibody normal range is typically negative, meaning the absence of detectable levels of AQP4 antibodies. Any positive result is clinically significant.
