About this service

This test measures the concentration of clonazepam in the blood serum as part of therapeutic drug monitoring (TDM). Clonazepam is a long-acting benzodiazepine used as an anticonvulsant (to treat certain types of epilepsy) and as an anxiolytic. Its level is measured to improve clinical efficacy, reduce side effects (such as drowsiness, dizziness, and ataxia), and monitor adherence to treatment, particularly in cases that do not respond as expected.
