Reference Range
Dehydroepiandrosterone (DHEA) can be measured with radioimmunoassay, liquid chromatography–mass spectrometry (LC-MS), or chemiluminescent techniques, and the reference range varies by the technique used.
The reference ranges for DHEA concentrations measured with LC-MS are listed in Table 1.
