Epilepsy

Epilepsy is a common neurological disorder affecting approximately 4-10 in every 1,000 people.1 Labcorp offers one of the most comprehensive suites of epilepsy tests and services to help you provide patients and families with the answers they need.

From initial screening through diagnosis and follow up, Labcorp supports the continuum of your patients’ care with:

  • Autoimmune epilepsy antibody testing
  • Genetic testing (NGS) panels
  • Genetic counselling services
  • Therapeutic drug level testing
  • Biochemical and metabolic testing

Genetic Testing (NGS) Panels

Approximately 70-80% of epilepsy cases are believed to be due to one or more genetic factors.2,3 Testing for epilepsy-related genes may be helpful for clarifying diagnosis and prognosis, selecting optimal treatments, and revealing information for family planning.4 Labcorp offers two genetic testing options: Clinical Epilepsy NGS Panel (630550): 46 genes, and Comprehensive Epilepsy NGS (630268): 811 genes.

Autoimmune Epilepsy Evaluation Panel (505490)

This test provides an evaluation of possible autoantibodies in patients with suspected autoimmune epilepsy, and optimizes the likelihood of detecting neuronal specific autoantibodies.

Genetic Counseling Resources

Genetic counseling services are available to help patients understand their risk and results from NGS panels. Patients can schedule an appointment by calling 855-GC-CALLS or 855-422-2557.
