Test Overview
Chemiluminescent Immunoassay (CLIA)
Establish the presence of a functioning corpus luteum or luteal cell function; confirm basal body temperature measurements for the occurrence of ovulation, evaluate the functional state of the corpus luteum in infertility patients, assess placental function during pregnancy. Ovarian function test.
Adult female: follicular phase 0.2 - 1.6 ng/mL; luteal phase 3.0 - 22.0 ng/mL; mid-luteal phase 5.0 - 22.0 ng/mL; aged >60 yrs: 0.2 - 0.6 ng/mL; oral contraceptives < 0.2 ng/mL. Adult male: 0.2 - 0.9 ng/mL.
* Reference ranges may change over time. Please refer to the original patient report when evaluating results.

Additional Information
Progesterone levels are most helpful when correlated with an endometrial biopsy and basal body temperature curves in nonpregnant subjects in assessing ovarian function. Serum progesterone levels may be increased in association with: choriocarcinomas (including ovarian), ovarian arrheroblastoma, adrenal cortical hyperfunction, ovarian (luteal) cysts, hydatidiform mole, and pregnancy. Decreased or absent serum progesterone may occur in association with, benign neoplasms of the breast and ovary, granulosa cell, lutein cell, and theca cell tumors of the ovary; ovarian and interior pituitary hypofunction, pregnancy complicated by intrauterine fetal death, some patients with hydatidiform mole, and eclampsia.
