- Ubiquinone 50
High-pressure liquid chromatography (HPLC) with electrochemical detection
Coenzyme Q10 (CoQ10; Ubiquinone 50) is an endogenous compound found in most human tissues. It possesses multiple cellular and extracellular functions, primarily based on it ability to undergo redox cycling. Such redox cycling plays an important role in vivo. Examples include CoQ10's involvement in ATP synthesis (as part of the electron transport chain of the inner membrane of the mitochondrion) and its ability to act as an antioxidant in the prevention of lipid peroxidation.
Plasma, frozen and protected from light
Green-top (heparin) tube, amber plastic transport tube with amber-top. (If amber tubes are unavailable, cover standard transport completely, top and bottom, with aluminum foil. Identify specimen with patient name directly on the container and on the outside of the aluminum foil. Secure with tape.) For amber plastic transport tube and amber-top, order LabCorp N° 23598.
Draw blood into chilled green-top tube. Gently invert five to six times to mix with preservatives. Keep unopened vacuum tube on ice before processing. Immediately separate plasma from red cells by centrifugation. Plasma must be separated from cells within 45 minutes of venipuncture. Transfer plasma specimen to a labeled amber transport tube and freeze on dry ice. Protect from light. To avoid delays in turnaround time when requesting multiple tests on frozen samples, please submit separate frozen specimens for each test requested.
Freeze plasma in plastic amber transport tube with amber-top on dry ice. Protect from light. (Where dry ice is not available at the collection site, the sample may be kept refrigerated or frozen at -20°C for three days, at which time it must be transferred to dry ice for storage. Samples must be shipped to the laboratory on dry ice.)
14 days at -70°C
Causes for Rejection
Use of EDTA anticoagulant;1 specimen not protected from light; plasma not frozen within 24 hours of collection
