Order Coenzyme Q10 (CoQ10) Blood Test from JustLabs for $52. Price includes lab processing at Quest Diagnostics. A one-time $18 collection fee applies per order. No insurance required.
Coenzyme Q10 (CoQ10) is a vital antioxidant that supports cellular energy production in every cell of your body, particularly in the heart, liver, and kidneys.
Coenzyme Q10 (CoQ10), also known as ubiquinone, is a naturally occurring compound essential for cellular energy production. It plays a critical role in the mitochondria—the powerhouses of your cells—where it helps convert food into ATP (adenosine triphosphate), the energy currency your body uses for every function.
Beyond energy production, CoQ10 serves as a powerful antioxidant, protecting cells from oxidative damage caused by free radicals. It's particularly concentrated in organs with high energy demands like the heart, liver, kidneys, and muscles.
CoQ10 levels naturally decline with age, typically peaking in your 20s and decreasing significantly after age 40. Additionally, statin medications, commonly prescribed for cholesterol management, can deplete CoQ10 levels by 20-40% because they block the same pathway the body uses to produce CoQ10. This depletion may contribute to statin-related muscle pain and fatigue experienced by some patients.
Testing CoQ10 levels helps identify deficiency, guide supplementation decisions, and optimize your cellular energy and antioxidant status. This is especially important for individuals on statin therapy, those with heart conditions, chronic fatigue, or anyone interested in supporting their cellular health.

What's Measured
What This Test Measures
This test measures the total concentration of Coenzyme Q10 in your blood serum. CoQ10 exists in two forms: ubiquinone (oxidized) and ubiquinol (reduced), and this test provides your total CoQ10 level which reflects your body's overall CoQ10 status and availability for cellular energy production.
Who Should Consider This Test
Anyone taking statin medications for cholesterol management, individuals with heart conditions or heart failure, people experiencing unexplained fatigue or muscle weakness, those with mitochondrial disorders, older adults concerned about age-related CoQ10 decline, athletes and active individuals optimizing cellular energy, and anyone interested in their antioxidant and cellular health status.

When to Get Tested
No fasting is required for this test. Blood can be drawn at any time of day. If you take CoQ10 supplements, testing is typically done in the morning before your daily dose to measure baseline levels. For accurate monitoring, try to test at consistent times.
Understanding Your Results
Results show your CoQ10 concentration in micrograms per milliliter (mcg/mL). Normal reference ranges typically fall between 0.5-1.5 mcg/mL, though optimal levels for therapeutic benefit may be higher (1.0-2.5 mcg/mL), especially for heart health. Levels below 0.5 mcg/mL suggest deficiency that may benefit from supplementation. Your healthcare provider will interpret results in the context of your medications, symptoms, and health goals.
What to Expect
After placing your order, you'll receive an email from Rupa Health (our lab order partner) within 24 business hours to sign a consent form and schedule your blood draw at a Quest Diagnostics location.
The blood draw typically takes just a few minutes. Results are usually available within 5-7 business days and will appear in your secure Justlabs dashboard.
Our results include reference ranges and easy-to-understand indicators showing whether your values are within normal limits.
