Valproic acid (Depakote) is used for various seizure types, mood stabilization in bipolar disorder, and migraine prevention. While it has a relatively wide therapeutic range, blood level monitoring helps confirm effective dosing and identify potential toxicity.
This test is used to confirm therapeutic levels, evaluate suspected toxicity (tremor, drowsiness, confusion, liver dysfunction), guide dose adjustments, monitor compliance, and manage drug interactions. Periodic liver function and complete blood counts are typically monitored alongside drug levels. Sample type is serum or plasma.
