What happens after I get my results?

You'll receive doctor notes in simple language explaining whether your lithium level is in the therapeutic range and what that means for your treatment. These notes include personalized guidance on whether your dose needs adjustment, what symptoms to watch for, and when to retest. Along with your standard lab report, you can use our trends feature to track your lithium levels over time, which is especially helpful for working with your psychiatrist to optimize your medication.

When will I get my results?

Most lithium test results are typically available within 1-2 business days after your blood sample reaches the lab. Your doctor may want to review results promptly to ensure your levels are safe and therapeutic, especially if you're experiencing any symptoms or just started the medication.

Who should consider getting this test?

Anyone taking lithium medication for bipolar disorder, mania, or mood stabilization needs regular lithium testing. It's especially important when starting the medication, after dose changes, if you experience side effects like tremors or confusion, or if you have conditions affecting kidney function that could change how your body processes lithium.

What symptoms indicate I may need this test?

If you're on lithium and experience tremors, nausea, confusion, excessive thirst, frequent urination, or coordination problems, you should get tested immediately as these may signal high lithium levels. Even without symptoms, regular testing is necessary because lithium levels can change based on hydration, diet, and kidney function.

What does high lithium mean?

High lithium levels mean too much medication is in your bloodstream, which can be toxic. Symptoms may include severe tremors, confusion, slurred speech, muscle weakness, or nausea. If your level is too high, your doctor will likely lower your dose or temporarily stop the medication while monitoring you closely.

What does low lithium mean?

Low lithium levels indicate there's not enough medication in your system to effectively stabilize your mood. This can lead to breakthrough manic or depressive episodes. Your doctor may increase your dose or check if you're taking the medication as prescribed and whether other factors are affecting absorption.

How often should I retest my lithium levels?

When first starting lithium or after dose changes, you'll typically need testing every 5-7 days until stable. Once your levels are stable and therapeutic, testing every 3-6 months is common. More frequent testing may be needed if you're ill, dehydrated, starting new medications, or experiencing symptoms that suggest your levels have changed.
