Overview of Anti AQP4 (NMO IgG) Antibody in Idukki
What is the Anti Aquaporin-4 NMO IgG Antibodies test?
This test detects antibodies against aquaporin-4, a protein found in the central nervous system. It is primarily used to diagnose neuromyelitis optica spectrum disorders (NMOSD), a rare autoimmune condition affecting the optic nerves and spinal cord.
Why is this test done?
It is used to confirm a diagnosis of NMOSD and differentiate it from multiple sclerosis, which can have similar symptoms but requires different treatment approaches.
How is the test performed?
A blood sample is analyzed using a cell-based immunofluorescence assay or ELISA to detect anti-aquaporin-4 antibodies.
What do the results mean?
A positive result strongly supports the diagnosis of NMOSD. Negative results do not rule out the disease completely, especially in early stages.
Are there any precautions or preparations required?
No special preparation is required. The test can be performed alongside other neurological investigations.
