Test ID: Q10    
Coenzyme Q10, Reduced and Total, Plasma

Method Description Describes how the test is performed and provides a method-specific reference

Coenzyme Q10 (CoQ10) is extracted from plasma with cold 1-propanol containing coenzyme Q9 as an internal standard. An aliquot of the lipid extract is fractionated by high-performance liquid chromatography (HPLC). The separated coenzyme Q10 reduced and coenzyme Q10 oxidized are quantified by measurement of selective coulometric response emerging from the chromatographic column.(Tang PH, Miles MV, DeGrauw A, et al: HPLC analysis of reduced and oxidized coenzyme Q[10] in human plasma. Clin Chem 2001 February;47[2]:256-265)

Day(s) and Time(s) Test Performed Outlines the days and times the test is performed. This field reflects the day and time the sample must be in the testing laboratory to begin the testing process and includes any specimen preparation and processing time required before the test is performed. Some tests are listed as continuously performed, which means assays are performed several times during the day.

Tuesday, Friday

Analytic Time Defines the amount of time it takes the laboratory to setup and perform the test. This is defined in number of days. The shortest interval of time expressed is "same day/1 day," which means the results may be available the same day that the sample is received in the testing laboratory. One day means results are available 1 day after the sample is received in the laboratory.

3 days (not reported Saturday or Sunday)

Maximum Laboratory Time Defines the maximum time from specimen receipt at Mayo Clinic Laboratories until the release of the test result

5 days

Specimen Retention Time Outlines the length of time after testing that a specimen is kept in the laboratory before it is discarded

1 month

Performing Laboratory Location Indicates the location of the laboratory that performs the test
