Progesterone

Item Value
Test Update Information Effective June 2, 2010, the Progesterone values will read approximately 10% lower due to a restandardization of the calibrator materials from the reagent vendor. This new restandardization will bring results closer to Gas Chromatography-Mass Spectrometry (GC-MS) values.

Additional information This assay is performed in-house and is suitable for use in adult patients to assess general endocrine function.

Samples from younger patients are referred to a reference laboratory employing a more sensitive assay (see entry for Progesterone, Ultrasensitive)

To convert µg/L to nmol/L (SI units) multiply by 0.0318.

See also Hydroxyprogesterone, 17-.

Adult male reference range established from in house Donor samples obtained from the UCSF Blood Donor Center (excluding autologous donors). Female reference ranges are adopted from the manufacturer, Siemens Diagnostics Centaur reagent insert.

This assay standardization is traceable to gas chromatography-mass spectroscopy (GCMS).
