Micronutrient, Coenzyme Q10 (CoQ10) Test
The Coenzyme Q10 (CoQ10) test measures the concentration of Coenzyme Q10 in a blood sample. Quest describes it as sometimes used to assess nutritional status related to cholesterol-lowering therapy and vascular risk factors.
About this test
Coenzyme Q10 is measured in serum using liquid chromatography/tandem mass spectrometry, a highly sensitive laboratory method for detecting small molecules. Quest describes this test as used for people on statin therapy, whether or not they have muscle-related symptoms, for people with high cholesterol, and for people without symptoms who are considered at risk for vascular disease.
The sample is protected from light before analysis.
