A lithium level test measures the amount of lithium in the blood. Lithium is a medication used in some mental health conditions, and its level must be kept within a narrow range to remain effective while avoiding toxicity. Clinicians order this test to monitor therapy, confirm that a therapeutic level has been reached, or check for a level that is too high. Because lithium is cleared by the kidneys, hydration and other medications can influence results. Testing is a monitoring tool and does not by itself determine treatment. A healthcare provider interprets the level alongside timing, symptoms, and kidney function.

• Lithium (serum) The concentration of lithium in the blood, used to monitor therapy and keep the level within its therapeutic range.

• People who have been prescribed lithium and need routine level monitoring
• Individuals starting or adjusting lithium therapy under a clinician's care
• People with symptoms such as tremor, nausea, or confusion that could relate to a lithium level
• Those with changes in kidney function or hydration that may affect lithium clearance
• Anyone taking other medications that can interact with lithium

• Timing matters: the sample is usually drawn as a trough, often about 12 hours after the last dose, exactly as instructed
• Stay normally hydrated unless your healthcare provider advises otherwise
• Take medications only as directed; do not change or skip doses without guidance
• No fasting is required unless combined with another test that needs it
• Tell the lab about all other medications and supplements

A lithium level is compared against a target range set for your treatment. A level below that range may suggest the dose is not producing the intended exposure, while a level above it may raise concern for toxicity, especially with symptoms such as tremor, unsteadiness, or nausea. Timing since the last dose, hydration, and kidney function all affect the reading. This is a monitoring test, not a diagnosis. Discuss the number with your prescribing healthcare provider, who can interpret it and adjust therapy if needed.
