Molecular genetic testing for epilepsy

Also known as: molecular diagnostics.

What is molecular genetic testing for epilepsy?

Molecular genetic testing refers to a wide variety of tests performed on blood and tissue to screen for genetic disorders. The epilepsy panel test specifically looks for variations in DNA that can predispose people to disorders that cause epilepsy. Identifying these can determine whether an infant may develop these disorders, or if parents can pass the traits along to their children.

What happens during the procedure?

All that’s required for the test is a basic blood draw, typically from the arm but sometimes from another area of the body. Then the blood sample is taken to a laboratory for testing.

Is any special preparation needed?

No special preparation is needed for the test.

What are the risk factors?

There are slights risks of infection, bleeding, bruising or swelling related to the blood draw.
