Description
Why It’s Done:
The Levetiracetam Assay Test is typically performed to:
• Monitor therapeutic levels: To ensure that the medication is within the effective therapeutic range, helping to control seizures while minimizing side effects.
• Adjust dosage: If a person is experiencing side effects or if their condition is not being adequately controlled, the test can help guide adjustments to the dosage.
• Assess drug interactions: Levetiracetam levels can be affected by other medications, so the test can help determine if drug interactions are influencing its effectiveness.
• Evaluate kidney function: Since levetiracetam is primarily cleared by the kidneys, kidney function can impact how the drug is metabolized and eliminated. The assay helps assess whether the dosage needs to be adjusted for patients with kidney issues.
• Monitor individuals on long-term therapy: For individuals on levetiracetam for extended periods, regular monitoring of blood levels is necessary to ensure safe and effective use.
Preparation:
• Fasting is not required for the test, but some healthcare providers may ask for it depending on the situation.
• A blood sample will be drawn, typically from a vein in your arm. The blood should be taken at a steady state of medication, usually just before the next dose is due (known as a trough level) to measure the lowest concentration of the drug.
• Inform your healthcare provider about all medications and supplements you are taking, as some drugs may interact with levetiracetam and affect its levels in the blood.
• If you experience side effects such as dizziness, fatigue, or nausea, make sure to report them to your healthcare provider, as these can be related to the medication’s level in the bloodstream.
