Autoimmune Encephalopathy Profile
Also known as: Autoimmune Encephalitis Panel, Paraneoplastic
Use
For the detection of antineuronal autoantibodies that help in the diagnosis of paraneoplastic syndromes and autoimmune encephalopathies and related conditions
Special Instructions
Consider this profile for differential evaluation of encephalopathy of unknown origin. For adults and patients suspected of having cancer, further evaluation with the Autoimmune Neurology/Paraneoplastic Profile is suggested.
Limitations
The test has been developed and its performance characteristics determined by Labcorp in accordance with CLIA requirements. However, it has not received clearance or approval from the FDA. The presence of these autoantibodies does not exclude idiopathic or paraneoplastic autoimmune encephalopathies, and titers may be lower in individuals without paraneoplastic syndromes, requiring clinical correlation.
