Radioimmunoassay of plasma and salivary progesterone during the menstrual cycle. 1984

L Cedard, and Y Janssens, and G Tanguy, and J R Zorn

We have developed specific and sensitive radioimmunoassays for progesterone in saliva (SP4) easily applicable in routine practice to assess ovarian function. One of them uses [3H]progesterone, the other 3-CMO-[125I]histamine as tracer. The reliability criteria of both techniques have been controlled and the results obtained with the two methods in 50 saliva samples are correlated well. Our clinical study has been chiefly done with [3H]progesterone. In the present study we reported the values obtained daily during the greatest part of the menstrual cycle in 14 normal cases and they are in agreement with previous reports. The use of [125I]tracer, by increasing the sensitivity of the RIA and shortening the duration of the assay, improves the use of SP4 as a practical non-invasive sampling alternative for many clinical situations involving evaluation of the ovarian function.

UI MeSH Term Description Entries
D008598 Menstruation The periodic shedding of the ENDOMETRIUM and associated menstrual bleeding in the MENSTRUAL CYCLE of humans and primates. Menstruation is due to the decline in circulating PROGESTERONE, and occurs at the late LUTEAL PHASE when LUTEOLYSIS of the CORPUS LUTEUM takes place.
D011374 Progesterone The major progestational steroid that is secreted primarily by the CORPUS LUTEUM and the PLACENTA. Progesterone acts on the UTERUS, the MAMMARY GLANDS and the BRAIN. It is required in EMBRYO IMPLANTATION; PREGNANCY maintenance, and the development of mammary tissue for MILK production. Progesterone, converted from PREGNENOLONE, also serves as an intermediate in the biosynthesis of GONADAL STEROID HORMONES and adrenal CORTICOSTEROIDS. Pregnenedione,Progesterone, (13 alpha,17 alpha)-(+-)-Isomer,Progesterone, (17 alpha)-Isomer,Progesterone, (9 beta,10 alpha)-Isomer
D011863 Radioimmunoassay Classic quantitative assay for detection of antigen-antibody reactions using a radioactively labeled substance (radioligand) either directly or indirectly to measure the binding of the unlabeled substance to a specific antibody or other receptor system. Non-immunogenic substances (e.g., haptens) can be measured if coupled to larger carrier proteins (e.g., bovine gamma-globulin or human serum albumin) capable of inducing antibody formation.

D012463 Saliva The clear, viscous fluid secreted by the SALIVARY GLANDS and mucous glands of the mouth. It contains MUCINS, water, organic salts, and ptylin. Salivas
