What's this test for?

This test is ideal if you're experiencing jitteriness, a racing heart, trouble sleeping, or headaches that could be related to too much caffeine in your system. It's also useful if you're monitoring caffeine exposure in a newborn being treated with caffeine or theophylline for breathing issues. Checking your caffeine level can help explain unexplained symptoms tied to stimulant intake.

What happens after I get my results?

Your results will show up in your account with the normal caffeine range explained so you know exactly where your level falls. If your level is high, simple next steps include cutting back on coffee, tea, energy drinks, and certain medications, then retesting after a few weeks to see the change. If a value looks dangerously high, especially in an infant, seek medical care right away. You can also download a standard lab report and track your caffeine levels over time using the trends feature in your account.

What symptoms indicate I may need this test?

Common signs include a fast heartbeat, shakiness, anxiety, trouble falling or staying asleep, headaches, or an upset stomach after consuming caffeinated products. In infants being treated with caffeine or theophylline for breathing problems, signs like irritability or unusual fussiness may prompt a check. If you notice these symptoms regularly, testing can confirm whether caffeine is the cause.

How can I naturally support healthy caffeine levels?

Cutting back gradually on coffee, tea, soda, energy drinks, and chocolate can help lower caffeine buildup in your body. Staying well hydrated and eating regular meals also helps your body process caffeine more efficiently. Getting consistent sleep reduces the temptation to rely on caffeine for energy, which naturally keeps your intake lower.

When will I get my results?

Results are typically ready within about a week of your sample being tested at the lab. Once processed, they're uploaded directly to your secure online account for you to view and download at your convenience.

Who should consider this test?

Anyone who regularly consumes a lot of caffeinated beverages and wants to understand their intake, or who has symptoms like a racing heart or anxiety, may benefit from this test. It's also relevant for caregivers of premature infants being treated with caffeine or theophylline, since caffeine levels can build up more easily in newborns. People who take medications that interact with caffeine metabolism might also want to check their levels.

What is caffeine and why does it matter?

Caffeine is a natural stimulant found in coffee, tea, energy drinks, and some medications that affects your nervous system and heart rate. It matters because too much can cause anxiety, sleep problems, and heart palpitations, while unexpected levels in infants can signal how their body is processing related medications like theophylline. Knowing your caffeine level helps you understand how it might be contributing to symptoms you're feeling.

What does a high caffeine level mean?

A high result means more caffeine is circulating in your system than is typical, which can come from drinking a lot of caffeinated beverages, taking certain supplements, or in infants, from converting theophylline into caffeine. This can cause symptoms like a fast heartbeat, restlessness, or trouble sleeping. Reducing intake of caffeinated products and retesting later can help confirm the level comes back down.

What causes high caffeine levels?

High levels are usually caused by consuming a lot of coffee, tea, energy drinks, soda, or caffeine-containing supplements and medications. In premature infants, caffeine can also build up because their bodies convert theophylline into caffeine and clear it slowly until they're about 3-4 months old. Certain medications can also slow down how quickly your body breaks down caffeine, leading to higher levels.

How often should I retest?

If you've made changes to reduce your caffeine intake, retesting after a few weeks can show whether your level has dropped as expected. For infants being monitored during treatment, retesting frequency depends on their clinical situation and treatment plan. Otherwise, testing occasionally when symptoms arise is usually enough for most people.
