Blood Test for Lithium Levels

Ordering the Blood Test for Lithium Levels

Monitoring lithium in the blood helps people who use lithium as a mood stabilizer, especially for bipolar disorder, to keep their levels in a safe range. This test is important because lithium can build up in the body, leading to side effects like confusion, tremors, or kidney problems if not checked regularly. Interestingly, even small changes in hydration or salt intake can affect lithium levels, making regular monitoring helpful for those on this medication.

Ordering this test gives you:

• Clear information about your current lithium level in the blood.
• Guidance for your doctor to adjust your lithium dose if needed.
• Early detection of possible lithium toxicity before symptoms become severe.
• Support for checking kidney and thyroid function, which can be affected by lithium.
• Peace of mind by helping you avoid unwanted side effects from too much or too little lithium.

Who Should Consider Lithium Monitoring

People who take lithium for mood disorders, such as bipolar disorder, often need to check their blood levels to make sure the medication is working as intended. For example, someone who has recently started lithium and notices new symptoms like increased thirst or trouble concentrating may benefit from checking their levels to see if an adjustment is needed.

Ordering this test may also be helpful in these situations:

• Someone who has changed their dose of lithium recently.
• A person who has started or stopped other medications that could interact with lithium.
• Anyone experiencing new symptoms like nausea, dizziness, or tremors while on lithium.
• People with changes in kidney or thyroid function, as these organs help process lithium.
• Someone who has had a sudden change in fluid intake or dehydration, which can unexpectedly raise lithium levels.

Checking your lithium level helps your doctor make safe decisions about your medication, reducing the risk of side effects like confusion, memory loss, or kidney problems. Delaying this test could mean missing early signs of lithium buildup, which may lead to more noticeable symptoms or complications that are harder to manage later.
