Encephalitis Antibody Evaluation with Reflex to Titer and Line Blot, Serum
Quest Diagnostics
Sample type: Serum
Requires fasting: No
Phlebotomy required
Details
Encephalitis Antibody Evaluation with Reflex to Titer and Line Blot, Serum - The Encephalitis Antibody Panel provides an evaluation of possible autoantibodies in patients with suspected autoimmune encephalitis, and optimizes the likelihood of detecting neuronal specific autoantibodies, whether present singly or occurring as multiple autoantibodies.
Reflex testing uses predefined clinical logic to automatically order one or more follow-up tests based on the initial test results. Reflex tests are performed automatically without the intervention of the ordering practitioner. They are conducted using the same sample your Patient already provided. If reflex tests are required, there will be additional charges.
