Aids in diagnosis of stiff-person syndrome, limbic encephalitis, and other autoimmune neurologic disorders. May be used in monitoring treatment response in individuals who are antibody positive. For analysis in serum, refer to Glutamic Acid Decarboxylase Antibody (2001771).
Semi-quantitative Enzyme-Linked Immunosorbent Assay
Cerebral Spinal Fluid (CSF)
Transfer 1 mL CSF to an ARUP Standard Transport Tube. (Min: 0.5 mL)
Fluid other than CSF. Grossly hemolyzed specimens.
Ambient: 24 hours; Refrigerated: 1 week; Frozen: 3 months
A value greater than 5.0 IU/mL is considered positive for glutamic acid decarboxylase antibody (GAD AB CSF).
This assay is intended for the semi-quantitative determination of the GAD Ab in human CSF. Results should be interpreted within the context of clinical symptoms.
