A reversed-phase high-performance liquid chromatography-electrospray-tandem mass spectrometry assay (HPLC-ESI-MS/MS) was developed to quantitate cortisol, cortisone, 20 alpha- and beta-dihydrocortisol, 20 alpha- and beta-dihydrocortisone, tetrahydrocortisol, and tetrahydrocortisone. The technique was used to analyze perfusate from the isolated human placental lobule for
