Expected Turnaround Time
2 - 5 days
Turnaround time is defined as the usual number of days from the date of pickup of a specimen for testing to when the result is released to the ordering provider. In some cases, additional time should be allowed for additional confirmatory or additional reflex tests. Testing schedules may vary.

Test Details
Use
Evaluation of Autoimmune Encephalitis Antibody with Reflex to Titer
Limitations
Negative results do not exclude autoimmune encephalopathy or cancer.
This test does not detect Ma1 or Ma2 antibodies (alias Mata), which are sometimes associated with brainstem and limbic encephalitis in context of testicular germ cell neoplasms.
This test was developed and its performance characteristics determined by Labcorp. It has not been cleared or approved by the Food and Drug Administration.
Methodology
Cell-based Immunofluorescence (IFA)
Additional Information
The Encephalitis Antibody Panel provides an evaluation of possible autoantibodies in patients with suspected autoimmune encephalitis, and optimizes the liklihood of detecting neuronal specific autoantibodies, whether present singly or occurring as multiple autoantibodies.
