Coenzyme Q10 Blood Test is an antioxidant that contributes to the basic function of cells. It is particularly important to ensure that tissues with a high demand for energy, such as those in the heart, have the energy to function properly. A number of conditions, including cancer, diabetes, heart disease, HIV, Alzheimer’s, Parkinson’s disease, muscular dystrophy, and certain genetic disorders are associated with lower than normal levels of CoQ10. 

The body can naturally rebuild CoQ10 level through certain foods that are ingested. It is found in the highest concentrations in organ meats like animal liver and heart. CoQ10 is also found in beef, pork, chicken and fatty fish such as tuna, with the highest amounts in beef. 

Production of CoQ10 decreases as you age, therefore, older individuals appear to be deficient in this compound. Other causes of CoQ10 deficiency include nutritional deficiencies such as vitamin B6 deficiency, genetic defects in the synthesis or use of CoQ10, increased tissue demands as a result of disease, mitochondrial diseases, oxidative stress due to aging, and side effects of statin treatments.
