Salivary Progesterone, 96 Wells

Intended Use
Enzyme immunoassay for the in vitro diagnostic quantitative measurement of active free progesterone
(a female hormone) in saliva.
Measurements obtained by this device may be used in the diagnosis and treatment of disorders of the ovaries or placenta
and can be used as an aid for prediction of ovulation.

Summary
Progesterone (4-pregnene-3, 20-dione) is a C21 steroid hormone containing a keto-group (at C-3) and a double bond
between C-4 and C-5. Like other steroids, it is synthesized from cholesterol via a series of enzyme-mediated steps (1)
The steroid hormone Progesterone is a female sex hormone which, in conjunction with estrogens, regulates the accessory
organs during the menstrual cycle and it is particularly important in preparing the endometrium for the implantation of the
blastocyte and in maintaining pregnancy (2)
In non-pregnant women progesterone is mainly secreted by the corpus luteum whereas in pregnancy the placenta becomes
the major source (3,4). Minor sources for progesterone are the adrenal cortex for both sexes and the testes for males.
The Progesterone level in saliva represents the concentration of the active free Progesterone.
