Autoimmune pediatric Disorders

Designed specifically for children

Mayo Clinic Laboratories’ first-of-its-kind profile only includes antibodies pertinent to pediatric CNS disorders — all in one evaluation. The antibodies included are supported by clinical research, and test results can help with diagnosis and long-term treatment planning.

Autoimmune pediatrics

Key testing


  • Evaluates for the presence of multiple antibodies with known associations to pediatric-onset central nervous system disorders.
  • Requires both serum and spinal fluid samples for improved detection.
  • Enables insights on diagnosis, prognosis, and treatment response.
  • Facilitates treatment selection.



Our cell-based GABA-A receptor antibody test is recommended — in conjunction with other autoimmune neurology profiles — for patients who present with encephalopathy with seizures. These patients also typically have multifocal large cerebral temporal and extra-temporal T2 signal abnormalities without enhancement. GABA-A receptor antibodies are biomarkers of autoimmune encephalopathy, which may occur at any age and disproportionately affects children. GABA-A receptor antibodies are the third most common neuronal biomarker in children, behind only NMDA receptor and MOG antibodies. Because disease associated with the GABA-A receptor antibody is responsive to immunotherapy if treated early, accurate and timely testing is critical.

Key testing


  • Specific phenotype (88% of patients have refractory seizures).
  • Evaluating GABA-A receptor improves diagnostic sensitivity thereby increasing physician confidence.
  • Provides reliable confirmation of GABA-A receptor-associated disease without the need for reflex testing.
  • 75% of GABA-A receptor-positive patients had a partial or complete recovery with proper treatment.1
  • Direct a search for cancer when appropriate (thymoma).

Additional testing

Can be ordered as a standalone test in addition to the autoimmune encephalopathy, autoimmune epilepsy, or pediatric CNS autoimmune evaluations in patients who present with encephalopathy with seizures.
