What Is a Levetiracetam Test?
A levetiracetam test measures the amount of the anti-epileptic drug levetiracetam present in the blood. Doctors use it to check whether a patient's dose is within a safe and effective range. The test is also known as the levetiracetam serum test or Keppra blood test, and uses a venous blood sample collected from the arm.
What Does a Levetiracetam Test Measure?
The levetiracetam blood test analyses a single parameter in the blood sample. The table below explains what is measured and why it matters.
| Parameter | What It Tells Us |
|---|---|
| Levetiracetam | The amount of levetiracetam present in the blood at the time of collection. This confirms whether the drug is at a level that is likely to control seizures without causing side effects. |
Why Is a Levetiracetam Test Done?
A doctor may order a levetiracetam test for several reasons, from routine monitoring to investigating new or worsening symptoms.
Common Symptoms That May Require This Test
The following symptoms may prompt a doctor to check levetiracetam levels:
- Breakthrough seizures despite taking the medication regularly
- Unusual drowsiness or difficulty staying awake
- Persistent dizziness or unsteadiness
- Mood changes, irritability, or unexplained agitation
- Generalised weakness or fatigue
- Suspected non-compliance with the prescribed regimen
- Concern about possible drug toxicity
Conditions This Test Can Help Detect
The levetiracetam serum test is used to monitor and manage the following situations:
- Epilepsy, including partial seizures, myoclonic seizures, and tonic-clonic seizures
- Suspected levetiracetam toxicity
- Kidney disease, where the drug may accumulate due to reduced clearance
- Off-label use for conditions such as migraine prevention
Levetiracetam Test During Pregnancy
Epilepsy is one of the most common chronic neurological conditions managed during pregnancy. Levetiracetam is frequently prescribed in this period, but blood levels can fall significantly, with some studies reporting a decrease of up to 60% by the third trimester. This decline is linked to changes in renal clearance, metabolism, and drug distribution. Regular monitoring before, during, and after pregnancy is therefore considered essential for women on this medication.
Levetiracetam Test for Chronic Disease Monitoring
Levetiracetam is eliminated primarily through the kidneys, so patients with kidney dysfunction may need more frequent monitoring and possible dose adjustments. Ongoing therapeutic monitoring is also useful during significant physiological changes, such as puberty and ageing, and during periods of suspected non-compliance. It helps the treating doctor keep the drug within a safe and effective range over time.
How to Prepare and What to Expect
Preparing for a levetiracetam blood test is straightforward, but timing the sample collection correctly is important for an accurate result.
Do You Need to Fast?
No fasting is required before this test. However, the timing of your medication matters greatly. The sample should be drawn just before your next scheduled dose, not immediately after taking it. This is called a trough level and gives the most reliable reading.
Practical Tips Before Your Test
Keep the following points in mind before your appointment:
- Do not take your levetiracetam dose immediately before the blood draw; wait until after the sample is collected.
- For extended-release formulations, the sample should be drawn at least 12 hours after the last dose.
- If you have recently started the medication or changed your dose, wait 24 to 48 hours for the drug to reach a steady state before testing.
- Inform your doctor and the collection staff about all medications you are currently taking.
- Stay well hydrated and wear a loose-sleeved top for easy access to your arm.
Step-by-Step Procedure
Here is what to expect during sample collection:
- Ensure the sample is collected just before your next scheduled levetiracetam dose to capture the trough level accurately.
- A trained professional will clean a small area on your arm with an antiseptic wipe.
- A thin needle is used to draw a small blood sample from a vein in your arm. The process takes under two minutes.
- The sample is processed promptly, with serum or plasma separated from the cells within two hours of collection.
- The processed sample is then sent to the laboratory for analysis.
- Your digital report will be delivered within the turnaround time specified at the time of booking.
Factors That Can Affect Accuracy
Several factors can influence the reliability of your result:
- Collecting the sample too soon or too late after the last dose
- Reduced kidney function, which can slow drug clearance
- Use of gel-separator tubes during collection, which may absorb the drug and give a falsely low reading
- Cross-reactivity with brivaracetam if both drugs are being used simultaneously
- Age-related differences in drug metabolism, particularly in children and elderly patients
Understanding Your Levetiracetam Test Results
Your results should always be reviewed alongside your clinical history by a qualified doctor. The table below shows the generally accepted therapeutic range for levetiracetam.
| Parameter | Therapeutic Range | Unit |
|---|---|---|
| Levetiracetam (trough) | 10.0 to 40.0 | µg/mL |
These ranges are general guidelines. Your doctor will interpret your results based on your age, health history, and other factors. Always consult a qualified healthcare professional for personalised medical advice.
Most patients respond well when levels fall within this range. However, some individuals may respond at lower levels, while others may experience side effects even within the range. Toxic thresholds have not been firmly established for this drug.
Results During Special Conditions
Certain health states can significantly alter levetiracetam levels and how results should be read.
- Pregnancy causes levetiracetam levels to drop, sometimes by as much as 60%, particularly in the third trimester. This is due to faster kidney clearance, changes in how the body absorbs and distributes the drug, and increased metabolism.
- Kidney impairment slows the removal of levetiracetam from the body, which can cause levels to rise. The drug's half-life is longer in elderly patients and in those with reduced kidney function, necessitating dose adjustment.
- In critically ill patients, drug clearance may actually increase, potentially leading to lower-than-expected levels and reduced seizure control.
How to Maintain Healthy Levels
The following general habits support consistent medication management:
- Take every dose at the same time each day, as prescribed, to keep levels stable.
- Keep all follow-up appointments so your doctor can track trends over time.
- Stay well-hydrated and report any new symptoms, side effects, or missed doses to your doctor promptly.

Frequently Asked Questions
The levetiracetam test measures the drug's concentration in the blood to confirm it is at a level that is both effective for seizure control and safe. It helps doctors adjust doses, confirm that a patient is taking their medication, and identify potential toxicity.
The sample should be collected at the trough, meaning just before the next scheduled dose. This timing gives the most consistent and clinically meaningful reading of the drug's level in the body.
No. Fasting is not needed before a levetiracetam blood test. The key preparation step is timing your blood draw correctly, ideally just before your next dose is due.
Anyone prescribed levetiracetam may benefit from periodic monitoring, particularly those starting treatment, adjusting their dose, or experiencing breakthrough seizures. Patients with kidney disease need especially close monitoring, as the drug is cleared through the kidneys and levels can build up if kidney function is reduced.
Yes, levetiracetam levels tend to decline as pregnancy progresses, largely due to faster kidney clearance and changes in how the body processes the drug. Levels may also fluctuate in the period after delivery. Regular monitoring during and after pregnancy is recommended to maintain seizure control.
The standard immunoassay used for this test is known to cross-react with brivaracetam, another anti-seizure drug. Patients who are taking both medications or switching between them should speak to their doctor, as a different laboratory test may be needed for accurate results.
Common side effects associated with levetiracetam include sedation, fatigue, mood swings, headache, irritability, and memory difficulties. A tingling sensation or decline in mental sharpness has also been reported. If you notice any of these, or if your seizures become more frequent, consult your doctor, who may order a levetiracetam serum test to review your current level.
