Coenzyme Q10


For: , ,

Quest Diagnostics Test Code: 19826

Coenzyme Q10 (CoQ10) is a fat soluble cofactor that is essential for energy producing metabolic pathways and for the proper functioning of the mitochondrial oxidative system. With insufficient CoQ10, the electron transfer activity of the mitochondria decreases, resulting in a net failure to produce the energy necessary to run the cell.

Coenzyme Q10 (CoQ10) acts as a catalyst for the respiratory chain. It is a fat-soluble quinone which has properties similar to vitamin E and K. It is needed in the process of making energy from carbohydrates. It is found in high amounts in the mitochondria. Additionally, CoQ10 is a powerful antioxidant, clearing the body from free oxygen radicals which can cause damage to cells. This test is used to detect mitochondrial deficiencies, and can also be used to monitor patients on statin therapies or patients receiving treatment for Parkinson’s and Alzheimer’s disease.
