What's this test for?

This test is ideal if you're experiencing persistent fatigue, muscle weakness, or low energy, especially if you're taking statin medications for cholesterol. CoQ10 levels can help explain why you might feel tired or have muscle discomfort, as this nutrient is essential for energy production in your cells and heart health. Many people use this test to uncover hidden factors affecting their vitality and cardiovascular wellness.

How should I prepare for this test?

Fasting is not required for this test. However, you should not take CoQ10 supplements on the morning of your test, as this could interfere with accurate measurement of your natural levels. You may continue taking other nutritional supplements and medications as usual prior to testing.

What's included in this test?

Coenzyme Q10(3)

This test measures Coenzyme Q10 (also known as CoQ10, ubiquinone, or ubiquinol), a vital antioxidant that your cells use to produce energy and protect against oxidative damage. CoQ10 is especially important for heart health and muscle function, and levels can become depleted by statin medications, aging, or certain health conditions. Understanding your CoQ10 status helps identify potential causes of fatigue and assesses your cardiovascular wellness.

What happens after I get my results?
You'll receive detailed doctor notes in simple language explaining what your CoQ10 levels mean for your energy, heart health, and overall vitality. These notes include personalized recommendations like dietary changes, supplement suggestions, or lifestyle modifications to optimize your levels. You'll also get the standard lab report and can track your CoQ10 levels over time using our trends feature to see how your interventions are working.
Who should consider getting this test?
This test is valuable for anyone taking statin medications (with or without muscle symptoms), individuals with high cholesterol, and those at risk for heart disease with low HDL or ApoA1 levels. It's also helpful if you're experiencing unexplained fatigue, muscle weakness, or reduced exercise tolerance, as low CoQ10 can contribute to these symptoms.
What symptoms indicate I may need this test?
Consider this test if you experience persistent tiredness that doesn't improve with rest, muscle weakness or discomfort (especially if taking statins), reduced stamina during exercise, or general low energy throughout the day. Other indicators include being on cholesterol-lowering medications or having concerns about your cardiovascular health and wanting to optimize your heart function.
How can I naturally support my CoQ10 levels?
You can boost CoQ10 through diet by eating foods rich in this nutrient like fatty fish (salmon, mackerel), organ meats (heart, liver), whole grains, and spinach. Regular moderate exercise and managing stress can help your body use CoQ10 more efficiently. If you're on statins, talk to your doctor about CoQ10 supplementation, as these medications can deplete your natural levels significantly.
What is CoQ10 and why does it matter?
Coenzyme Q10 is a naturally occurring antioxidant that your body produces and stores in the mitochondria (the energy factories of your cells). It plays a critical role in producing ATP, the energy currency your body uses for all functions, and is especially concentrated in your heart, which requires enormous amounts of energy. Low CoQ10 levels can affect energy production, heart function, and your body's ability to fight oxidative stress.
What does low CoQ10 mean?
Low CoQ10 levels suggest your cells may not be producing energy as efficiently as they should, which can lead to fatigue, muscle weakness, and reduced physical performance. This is particularly common in people taking statin medications, as statins block the same pathway your body uses to make CoQ10. Low levels may also indicate increased oxidative stress or reduced antioxidant protection for your heart and other tissues.
How often should I retest my CoQ10 levels?
If you're starting CoQ10 supplementation or making lifestyle changes, retesting in 8-12 weeks can show whether your levels are improving. For those on long-term statin therapy, testing every 6-12 months helps monitor your levels and ensure they remain adequate. If your initial results are normal and you're not on medications that affect CoQ10, annual testing is usually sufficient for monitoring.

What this means

Your CoQ10 levels are slightly below the optimal range. While not critically low, this may contribute to occasional fatigue, reduced stamina, or decreased cellular energy production, especially if you're taking statin medications. Optimizing your CoQ10 levels can support better energy and cardiovascular health.

* Regular blood test results (e.g., CBC) typically start arriving the next business day after sample collection. More complex tests, such as hormone panels, may take up to 10–15 business days due to their complexity.
