Also note new ordering guidelines:  This testing is intended to be ordered in adult patients. If this test is ordered on a patient younger than 18 years of age, this test will be cancelled and automatically reordered by the laboratory as Pediatric Autoimmune Encephalopathy/CNS Disorder Evaluation, Serum (test ID PCDES). Mayo Clinic Laboratories pediatric autoimmune CNS disorders evaluation is part of an evolving approach to testing for autoimmune neurological disorders using phenotypic-specific evaluations that include multiple antibodies known for their disease association.
