What is analysed?

Valproic acid is an anticonvulsant medicine used to treat epilepsy and bipolar disorder. The valproic acid test measures the level of valproic acid in the blood.

What does the result mean?

The result indicates the concentration of valproic acid in the blood.

Why conduct the analysis?

The valproic acid test ensures that the prescribed dose of valproic acid for treatment is appropriate for the patient.

When to conduct the analysis?

The valproic acid test is conducted on a regular basis, especially during the start of treatment to establish the appropriate dose of valproic acid. The analysis is also conducted when there are changes in the patient’s condition, when the dose needs to be adjusted, or when there are signs of valproic acid toxicity.

What sample is required?

A blood sample is used for the analysis of valproic acid levels. The blood is drawn from a vein, usually in the arm.

Is any prior preparation necessary?

Patients should fast for 8-12 hours before the blood sample is taken.

How is it performed?

The collected blood sample is sent to a laboratory, where it is analysed using techniques such as liquid chromatography or immunoassay to quantify valproic acid levels in the blood.

What are the normal values?

What does having altered values mean?

• Elevated levels: Raised valproic acid levels indicate an increased risk of toxicity, leading to symptoms like nausea, drowsiness, or even serious complications like liver damage.
• Low levels: Low valproic acid levels indicate an insufficient therapeutic effect, increasing the risk of seizures or mood swings.
