Coenzyme Q10 Serum Test
A CoQ10 blood test measures coenzyme Q10 levels in the bloodstream. CoQ10 supports energy production in cells and acts as an antioxidant, and testing can assess whether levels are low.

Quick answer
The CoQ10 blood test measures coenzyme Q10, a fat-soluble compound found in nearly every cell. CoQ10 helps mitochondria produce energy and functions as an antioxidant. Testing is most often used to evaluate whether levels are low in people with certain health conditions or dietary patterns. A healthcare provider interprets the result with your overall health picture.
What this test measures
This test quantifies coenzyme Q10, also called ubiquinone, in a blood sample. CoQ10 is involved in the electron transport chain that cells use to generate energy, and it also helps protect cell membranes from oxidative stress. Levels can vary with age, diet, and some medical conditions. Because CoQ10 is carried by lipoproteins, results are sometimes reported alongside cholesterol values for context.
A blood sample is collected by venipuncture at a partner laboratory. The laboratory measures total CoQ10 with a chromatographic method, and some reports include the ratio of CoQ10 to total cholesterol. A lipid panel can be ordered from the same sample because CoQ10 circulates bound to lipoproteins. Fasting may be requested when cholesterol and triglyceride values are part of the panel.
People order CoQ10 testing when they want to assess nutritional status, when a provider is evaluating fatigue or muscle concerns, or when monitoring levels over time. Reference ranges vary by laboratory, and results are interpreted with diet, health conditions, and other laboratory findings. The test provides information for an educational and clinical discussion and is not a standalone diagnosis.
- Total coenzyme Q10 (ubiquinone) level
- CoQ10 to total cholesterol ratio
- Total cholesterol
- HDL cholesterol
- LDL cholesterol
- Triglycerides
Why people order this test
- Assess coenzyme Q10 status when deficiency is a concern
- Provide context for fatigue or muscle-related evaluations
- Monitor CoQ10 levels over time
- Pair with a lipid panel because CoQ10 travels with lipoproteins
- Gather nutritional data for a provider discussion
How to prepare
Fasting for several hours may be requested when cholesterol and triglyceride testing is included, so follow the instructions on your order. A single blood draw is standard, and timing can matter because CoQ10 levels fluctuate. The laboratory will specify any collection requirements.
Understanding your results
Results are generally available within one to three business days. The report shows a CoQ10 concentration and, when ordered, a cholesterol ratio, both compared with the laboratory reference range. A healthcare provider interprets the value with your diet, health conditions, and related test results.

Frequently Asked Questions
What does coenzyme Q10 do in the body?
CoQ10 supports energy production in mitochondria and acts as an antioxidant that helps protect cells from oxidative damage.
Do I need to fast for a CoQ10 test?
Fasting may be requested if a lipid panel is included, since triglycerides are affected by recent meals. Follow your order instructions.
Can CoQ10 levels be low without symptoms?
Yes. Levels can be low without obvious symptoms, and low values are evaluated in the context of overall health and diet.
Why is cholesterol tested with CoQ10?
CoQ10 travels in the blood bound to lipoproteins, so cholesterol values help put the CoQ10 result in context.
How is the sample analyzed?
Laboratories typically use a chromatographic method that separates and measures CoQ10 in the blood sample.
