Description
Valproic Acid
Sample Type: Serum
Tests Included:
Measurement of valproic acid levels in the blood
Sample Required:
Blood sample drawn from a vein in the arm
Test Time:
Results are typically available within a day.
Test Range Values:
Therapeutic levels of valproic acid in the blood are usually between 50 and 100 micrograms per milliliter (mcg/mL). The target range may vary based on the individual’s condition and the healthcare provider’s recommendations.
What is the test?
The valproic acid test measures the concentration of valproic acid, an antiepileptic medication, in the blood. Monitoring valproic acid levels helps healthcare providers ensure that the drug is within the therapeutic range to effectively manage seizures while minimizing side effects and toxicity.
Test Procedure:
A healthcare professional collects a blood sample from the patient’s arm, and the sample is sent to the laboratory for valproic acid measurement.
When to take the test:
Valproic acid levels are monitored regularly to adjust the dosage and maintain therapeutic levels. Testing may be done before a dose (trough level) or a specific time after the dose (peak level) to assess absorption and elimination rates.
Who should take the test:
Patients prescribed valproic acid, especially those with epilepsy or bipolar disorder, may require regular monitoring of valproic acid levels to optimize the dosage and ensure the medication’s effectiveness and safety.
Precautions for exceptional cases (pregnancy, etc.):
Pregnant individuals and individuals with liver or kidney problems should inform their healthcare providers before the test, as valproic acid levels and dosages may need adjustments in these cases.

Q2: What symptoms indicate valproic acid toxicity?
A: Symptoms of valproic acid toxicity may include confusion, drowsiness, vomiting, loss of consciousness, and rapid heartbeat. It is essential to report any unusual symptoms to a healthcare provider promptly.
Q3: Can valproic acid levels be affected by other medications?
A: Yes, certain medications, such as phenobarbital or phenytoin, can affect valproic acid levels. It’s crucial to inform the healthcare provider about all medications being taken to interpret the valproic acid test accurately.
