Levetiracetam, Serum

This test measures the concentration of levetiracetam, an antiepileptic drug, in the blood to ensure therapeutic levels are maintained.

It helps in monitoring treatment effectiveness, adjusting dosage, and avoiding toxicity in patients receiving levetiracetam for seizure control.

A blood sample is drawn and analyzed using chromatography or immunoassay techniques to quantify drug levels.

Results are interpreted based on therapeutic reference ranges. Low levels may indicate inadequate dosing, while high levels may suggest overdose or risk of side effects.

Timing of sample collection in relation to the last dose is important. No fasting is required.
