Question: Is there a lab test that can measure CoQ10 in the blood? Can it help to determine the dosage I should take for a certain condition, like heart failure?
Answer: Yes, several well-known, national chain laboratories offer a test that measures CoQ10 levels in the blood. Although this test does not measure CoQ10 levels in heart tissue itself (which will differ from blood levels), it can reveal if you are below the normal range, and help your health care provider determine an appropriate dose for your condition, as well as monitor your response to certain drugs, like statins (which can lower blood levels of CoQ10). For more about this test, including the normal range for blood levels of CoQ10, see the CoQ10 and Ubiquinol Supplements Review >>
