What's this test for?

This test is ideal if you're taking lithium medication and need to confirm your body's cellular lithium levels are in a safe, effective range. It helps if you have concerns about whether your current dose is working properly or if you're experiencing side effects that might signal your levels are too high or too low. Many people use this alongside their regular lithium monitoring routine for extra insight into how their body is storing this mineral over time.

What happens after I get my results?

Your results will show up in your account with your lithium level clearly marked against the normal reference range so you know exactly where you stand. If your number falls outside the expected range, simple next steps include reviewing your dosage timing, staying consistent with hydration and salt intake, and retesting on a schedule that fits your situation. You can download a standard lab report straight from your account at any time, and the trends feature lets you track how your levels shift over weeks or months. If a result looks dangerously high or low, it's important to seek medical care right away.

Who should consider this test?

Anyone currently on lithium therapy who wants a closer look at how their body is handling the medication over time is a good candidate. It's also useful for people who've had inconsistent standard lithium level checks and want a different measurement approach to compare against. This test can be a helpful addition if you've noticed new symptoms like tremors, excessive thirst, or unusual tiredness.

What symptoms indicate I may need this test?
Common signs worth paying attention to include hand tremors, excessive thirst or urination, confusion, muscle weakness, or unusual fatigue. Nausea or an upset stomach that doesn't go away can also be a clue that your levels need checking. If any of these symptoms show up while you're on lithium, it's worth getting your levels checked instead of just waiting for your next scheduled check.
When will I get my results?
Results are typically ready within about 7 days of your sample being processed at the lab. You'll get a notification as soon as your report is available in your account, so there's no need to call and check in. Once ready, you can view, download, and start tracking your results right away.
How can I naturally support healthy lithium balance?
Staying well hydrated and keeping your salt intake steady day to day can help your body maintain more stable lithium levels, since dehydration and low sodium can cause levels to climb. Eating consistent meals and avoiding sudden changes in your diet also helps keep things predictable. Limiting caffeine and alcohol, which can affect hydration and kidney function, is another simple step worth considering.
What does high lithium mean?
A high result can mean your body has more lithium built up than expected, which sometimes happens with dehydration, kidney changes, or a dose that needs adjusting. Symptoms like tremors, confusion, or severe nausea alongside a high result should be treated seriously and may require urgent medical attention. Simple steps like checking your hydration and reviewing recent medication changes are good places to start, but a significantly high result paired with symptoms means you should seek medical care right away.
What does low lithium mean?
A low result may mean your current dose isn't reaching a level that's doing its job effectively for you. This can happen if doses are being missed, taken inconsistently, or if your body is processing the medication faster than expected. Keeping a simple log of when you take your medication can help identify patterns before your next check.
What causes high or low lithium levels?
Levels can shift due to how consistently a dose is taken, changes in kidney function, dehydration, big changes in salt intake, or interactions with other medications. Illness that causes vomiting or diarrhea can also throw off your levels quickly. Because so many everyday factors play a role, retesting after any major lifestyle or health change is a smart idea.
How often should I retest?
Retesting frequency really depends on how stable your levels have been and whether you've had any recent dose or lifestyle changes. Many people find checking every few months works well once things are stable, but more frequent checks make sense right after starting or adjusting a dose. Using the trends feature to watch your pattern over time can help you and your care routine figure out what cadence works best.
