The CoQ10 blood test measures the amount of coenzyme Q10 (CoQ10), a substance your body makes and uses for energy and cell protection. It is ordered when a clinician suspects low levels due to certain medications, diet, or symptoms like muscle weakness or fatigue.

What it measures

  • Total CoQ10 — The overall amount of CoQ10 in your blood.
  • CoQ10 (oxidized form) — The form that can build up when your body is under oxidative stress.
  • CoQ10 (reduced form) — The active form your body uses for energy.
  • CoQ10 ratio — The balance between oxidized and reduced forms, which may show how well your body manages stress.

Who it is for

A clinician may order this test if you take statins (cholesterol-lowering drugs) or have symptoms such as muscle pain, weakness, or fatigue that could relate to low CoQ10. It is not a routine screening test.

Preparation

No fasting is usually required. Tell your clinician about all supplements you take, as some can affect the result.

Results and what they mean

Results are reported as a number, often in micrograms per milliliter (mcg/mL), and may include a reference range. Your clinician will interpret the result based on your health, diet, and medications. This is general information, not medical advice; discuss your results with a qualified healthcare professional.
