Confirmatory Test for Anti-Seizure Medicines

North Carolina rates for HCPCS 80340

A laboratory test that identifies anti-seizure medicines in a blood or urine sample and confirms precisely which ones are present. Unlike a quick screening check, which only suggests that something in a group may be there, this test names the individual medicine. It is used to confirm that a prescribed medicine is being taken as directed, or to work out what someone has taken.
