HelpTest Code PROG PROGESTERONE
Additional Codes
P4
Methodology
Competitive Chemiluminescent Immunoassay
Progesterone is provided by the corpus luteum of the ovary in nonpregnant females, and by the placenta during pregnancy. Measurement of progesterone is useful in the investigation of whether ovulation occurs in a menstrual cycle, for predicting ovulation in induced cycles (where concentrations are generally higher than normal), and evaluation of placental function in pregnancy.
