What's this test for?

This test is ideal if you're experiencing unexplained muscle weakness, fatigue, or exercise intolerance that doesn't seem to have an obvious cause. It's also helpful if you have symptoms that suggest your body isn't processing energy normally, such as chronic tiredness or muscle pain after mild activity. Many people use this test to get a clearer picture of how well their cells are converting fuel into usable energy.

What's included in this test?

This test measures two related markers that show how your body is turning food into energy at the cellular level. Looking at both markers together, rather than just one, gives a clearer sense of whether your body's energy production process is working smoothly or is under stress.

What happens after I get my results?

Your results will show up in your account with the normal range for lactate and pyruvate clearly explained next to your values. If something falls outside the expected range, the report will point you toward simple next steps like adjusting activity levels, staying hydrated, or reviewing your diet, and if a value is significantly abnormal it will flag that you should seek medical care right away. You can download a standard lab report directly from your account at any time. If you retest later, the trends feature lets you track how your levels change over time.

How can I naturally support healthy energy metabolism?

Staying well hydrated and eating balanced meals with enough carbohydrates can help your body process energy more efficiently. Avoiding intense exercise right before testing, getting consistent sleep, and limiting alcohol can also support normal metabolic function. Gentle, regular movement like walking tends to support healthy energy processing better than sporadic intense workouts.

When will I get my results?

Results are typically ready within about 7 days of your sample being collected. Once ready, they'll appear automatically in your online account, and you'll be able to view, download, and track them right away.

Who should consider this test?

People dealing with ongoing muscle fatigue, cramping, or a general sense of low energy that hasn't been explained by other causes may want to consider this test. It can also be useful for athletes or active individuals who want to better understand how their body handles physical exertion. Anyone told they should monitor their metabolic energy processes may find this test helpful as well.

What symptoms indicate I may need this test?

Common symptoms include persistent muscle weakness, unusual fatigue after light activity, muscle cramps, or a general feeling of sluggishness that doesn't improve with rest. Some people also notice these symptoms worsen after eating certain foods or during physical exertion. If these symptoms are recurring and unexplained, this test can offer useful insight.

What does a high lactate result mean?

A high lactate level can mean your body is producing more of this byproduct than it can clear, often related to how your cells are generating energy. This can happen after intense exercise, but if it shows up without a clear physical cause, it may be worth looking into your diet, hydration, and activity patterns. Retesting after making lifestyle adjustments can help clarify whether the level was temporary or ongoing.

What causes abnormal lactate or pyruvate levels?

Levels can shift due to intense physical activity, dehydration, certain diets, or how efficiently your body's cells are converting fuel into energy. Temporary factors like recent exercise or fasting before the test can also influence results. Because so many everyday factors play a role, it's helpful to note your activity and eating habits before testing.

How often should I retest?

If your first results are within the normal range and you feel fine, retesting once a year or if new symptoms appear is generally enough. If your levels were outside the normal range, retesting in a few months after making lifestyle changes can help you see if things have improved. Tracking results over time in your account makes it easy to spot patterns.
