What's this test for?

This test is ideal if you're experiencing unexplained muscle weakness, fatigue, or low energy that doesn't improve with rest. It's also useful if you have concerns about how your body is processing fat for energy, since carnitine plays a key role in that process. Many people use this test to check for a carnitine imbalance that could be affecting their metabolism or muscle function.

What's included in this test?

This test measures the amount of carnitine excreted in a random urine sample, which reflects how well your body is managing this important nutrient. Carnitine helps transport fatty acids into cells so they can be converted into energy, so checking its levels gives insight into your metabolic efficiency and nutritional status.

What happens after I get my results?

Your results will be available in your account, with each value's normal range clearly explained so you know exactly where you stand. If your carnitine level is outside the expected range, simple next steps like adjusting your diet, discussing supplementation options, or retesting in a few months can help you monitor changes. A standard lab report is available to download directly from your account for your records. You can also track your results over time using the trends feature to see how your levels shift.

How can I naturally support healthy carnitine levels?
Eating more red meat, poultry, fish, and dairy can naturally boost your carnitine intake since these are the richest dietary sources. Staying well hydrated and maintaining a balanced diet also supports healthy kidney function, which affects how carnitine is filtered and excreted. Regular, moderate exercise can help your body use carnitine more efficiently for energy production. If you follow a vegetarian or vegan diet, you may want to pay closer attention to plant-based sources or discuss options with a nutrition-focused resource.
When will I get my results?
Results for this urine carnitine test are typically ready within about 7 days of your sample being received at the lab. You'll get a notification when your results are ready to view in your secure online account. This turnaround gives the lab time to run the necessary analysis accurately.
Who should consider this test?
This test is a good option for anyone experiencing unexplained fatigue, muscle weakness, or exercise intolerance that hasn't been explained by other causes. People with dietary restrictions, such as vegetarians or vegans, may also want to check their carnitine status since plant foods contain less of it. Athletes looking to understand their metabolic efficiency sometimes use this test as part of a broader nutritional picture.
What symptoms indicate I may need this test?
Common symptoms that might prompt this test include persistent muscle weakness, low energy or fatigue that doesn't improve with sleep, and reduced exercise tolerance. Some people also notice muscle cramps or a general feeling of sluggishness. If these symptoms are ongoing and unexplained, checking your carnitine levels can help rule out a nutritional or metabolic factor.
What does high carnitine in urine mean?
A higher-than-expected carnitine level in your urine can sometimes mean your body isn't reabsorbing it efficiently, or that your dietary intake is very high. In some cases, it can reflect how your kidneys are processing this nutrient. Simple next steps include reviewing your diet with an eye toward carnitine-rich foods and supplements, and considering a retest to confirm the pattern.
What does low carnitine in urine mean?
Lower carnitine levels in urine may suggest your body is holding onto more of it, which can sometimes happen with lower dietary intake, absorption issues, or increased demand from activities like intense exercise. Increasing carnitine-rich foods such as meat, fish, and dairy can help. If levels remain low or symptoms persist, retesting after dietary changes is a reasonable next step.
How often should I retest?
If your initial results are outside the normal range, retesting after 2-3 months of dietary or lifestyle changes can help you see if your levels have improved. For general monitoring, once or twice a year is typically sufficient unless you're actively managing a specific concern. Tracking your results over time in your account makes it easy to spot trends.

What this means

This result is above the typical range, which may mean your body is excreting more carnitine than usual. This can happen with high dietary intake or how your kidneys are processing the nutrient. It's not usually a cause for alarm on its own, but tracking it over time can help clarify the pattern.

* Regular blood test results (e.g., CBC) typically start arriving the next business day after sample collection. More advanced tests may take longer due to complexity.
