SPECIAL INSTRUCTIONS: DHEA supplementation causes a false elevation of values in this standard immunoassay method for progesterone. Physicians using progesterone levels as a criterion for triggering ovulation in an IVF cycle in patients supplemented with DHEA should assess progesterone levels using a LC/MS/MS Progesterone assay, such as test code 17183 performed at Quest Diagnostics San Juan Capistrano.

Rejection Criteria: Serum stored on barrier gel for more than 72 hours. Do not order progesterone testing as an add on to a barrier gel specimen older than 72 hours. Progesterone binds to barrier gel causing decreased values.
