Test ID: DHEA_    
Dehydroepiandrosterone (DHEA), Serum

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

Deuterated stable isotope d2 dehydroepiandrosterone (d2-DHEA) is added to a 0.4 mL serum sample as internal standard. The DHEA and internal standard are extracted from the sample by solid-phase extraction. This is followed by conventional liquid chromatography on a Cohesive LX4 System and analysis on a tandem mass spectrometer equipped with a heated nebulizer ion source.(Soldin OP, Guo T, Weiderpass E, Tractenberg RE, Hilakivi-Clarke L, Soldin SJ: Steroid hormone levels in pregnancy and 1 year postpartum using isotope dilution tandem mass spectrometry.

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

Monday, Thursday

Report Available The interval of time (receipt of sample at Mayo Clinic Laboratories to results available) taking into account standard setup days and weekends. The first day is the time that it typically takes for a result to be available. The last day is the time it might take, accounting for any necessary repeated testing.

2 to 6 days

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

2 weeks

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