DHEA Sulfate Assay Now Available in Clinical Chemistry Laboratory

Effective Wednesday, May 9, 2012, the University of Iowa Hospitals and Clinics core clinical laboratory will begin running the Roche Diagnostics assay for dehydroepiandrosterone sulfate (DHEA sulfate).  DHEA sulfate is typically ordered for workup of hyperadrenogenism (including polycystic ovarian syndrome), premature adrenarche, or as an adjunct in diagnosis of congenital adrenal hyperplasia.  This assay will be available in Epic as "DEHYDROEPIANDROSTERONE SULFATE" [LAB524] and replace the current mailout test which uses the same methodology and units of measurement.
