Use:
Work up women with infertility, amenorrhea, or hirsutism to identify the source of excessive androgen; aid in the evaluation of androgen excess (hirsutism and/or virilization), including Stein-Leventhal syndrome and adrenocortical diseases, including congenital adrenal hyperplasia and adrenal tumor. DHEA-S is not increased with hypopituitarism. It is low in Addison disease.
Limitations:
As with all tests containing monoclonal mouse antibodies, erroneous findings may be obtained from samples taken from patients who have been treated with monoclonal mouse antibodies or who have received them for diagnostic purposes.3 In rare cases, interference due to extremely high titers of antibodies to streptavidin and ruthenium can occur.3 The test contains additives that minimize these effects.
