About this test

What Is a Lithium Serum Test?
The lithium serum test is a blood test used to measure the concentration of lithium in the bloodstream. Lithium is a medication commonly prescribed to manage mood disorders such as bipolar disorder.

Why Lithium Monitoring Is Important
Monitoring lithium levels is essential to ensure the dosage remains within the therapeutic range. Levels that are too low may be ineffective, while levels that are too high can lead to toxicity and serious side effects.

Ensuring Safe and Effective Treatment
Regular lithium testing helps clinicians adjust dosages accurately, monitor treatment effectiveness, and minimise the risk of lithium toxicity.
