Preferred Specimen(s)

1 mL serum

Minimum Volume

0.5 mL

Collection 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 order code 17183 performed at Quest Diagnostics, San Juan Capistrano.

Note: Do not add on progesterone testing to a barrier gel specimen older than 72 hours.

Transport Container

Serum separator tube (SST)

Transport Temperature

Room temperature

Specimen Stability

  • Room temperature: 72 hours
  • Refrigerated: 7 days
  • Frozen: 28 days
  • Do not add on Progesterone testing to a barrier gel specimen older than 72 hours

Reject Criteria

Serum stored on barrier gel for more than 72 hours
