A lithium level test measures how much lithium is in your blood. It is ordered to check that lithium, a medicine used to treat some mood conditions, stays in a safe range and to help guide dose adjustments.

What it measures

  • Lithium concentration — The amount of lithium in your blood at the time of the draw.
  • Therapeutic range — The range where lithium is most likely to work and be safer for most people.
  • Trough level — A level drawn 8 to 12 hours after your last dose, when timing matters.
  • Toxic level — A level above the usual range, which needs prompt medical attention.

Who it is for

It is typically ordered by a prescribing clinician for people taking lithium, especially when starting, changing dose, or having side effects.

Preparation

No fasting is needed. Timing matters: most levels are drawn 8 to 12 hours after your last dose, so follow your clinician's instructions on when to take your dose.

Results and what they mean

Results are reported as a number, often with the reference range. Your clinician compares the number with your dose, symptoms, and other labs; this is general information, not medical advice, and only your clinician can interpret your result.

No. Fasting is not required for a lithium level.

Can other medicines affect the result?

Yes. Some medicines and dehydration can affect lithium levels, so tell your clinician about everything you take.
