Estriol: An estrogenic hormone found in the blood and urine during pregnancy.
Fallopian tube: A pair of slender ducts through which ova (eggs) pass from the ovaries to the uterus in the female reproductive system.
estriol - a hormone produced by the placenta and by the fetal liver and adrenal glands.
F
fetal fibronectin (FFN) - a protein that helps "glue together" the tissues of the placenta.
Estriol: A female sex hormone that increases during pregnancy.
Estrogen: The female sex hormone that controls the course of the menstrual cycle.
Fallopian tube: Either of two thin tubes that carry the egg from the ovaries to the uterus.
Estriol: A hormone produced by the fetus and passed into the mother's bloodstream. Levels of this hormone can be tested via a blood test (quad screen) during the second trimester.
Estriol-This hormone is a form of estrogen in the body. It is secreted by the placenta during pregnancy. One of the tests (with AFP) in a Triple Screen or Quad Screen.
Estriol - A type of estrogen that is produced by the placenta during pregnancy.
Estriol is a hormone produced by the baby's adrenal glands and if this level is low it can suggest that the baby is not developing properly or it may indicate a birth defect.
ESTRIOL EXCRETION STUDIES, NON-STRESS TEST, OXYTOCIN CHALLENGE TEST
These tests are also used to determine the health of the fetus.
SalEst--salivary estriol read in, of all things, the mother's saliva, under the theory that fetal estriol is released prior to the onset of active pre-term labor. It presents in the mother's saliva and her saliva can be tested every two weeks.
Maternal serum estriol
The amount of estriol in maternal serum is dependent upon a viable fetus, a properly functioning placenta, and maternal well-being.

Should the first-trimester aneuploidy screen be maternal age adjusted?
They usually include four biochemicals: maternal serum alpha-fetoprotein, human chorionic gonadotropin (hCG), a hormone produced in the placenta; inhibin A, another hormone; and unconjugated estriol-an estrogen produced by both the fetus and the ...
AFP, hCG, and estriol are tested together and are referred to as a triple screen. The quad screen refers to a test that measures AFP, hCG, and estriol but adds inhibin to improve its accuracy.
Currently, AFP is also being combined with measurements of estriol and HCG levels to screen for Down's syndrome and other chromosome abnormalities like trisomy 13 and trisomy 18.
Estrogen (estriol), which increases during pregnancy. It is produced in large amounts by the placenta. Estriol can be detected in the blood as early as the ninth week of pregnancy and continues to increase until delivery.
A group of steroid compounds that includes estradiol, estriol, and estrone. Estrogens are produced by the granulosa cells of developing egg follicles in the ovary, the corpus luteum, and the placenta.
Along with AFP, two hormones produced by the placenta are often measured - hCG and estriol. The level of these three substances can help doctors identify a fetus at risk for certain birth defects or chromosomal abnormalities.
The test checks for alpha-fetoprotein (AFP) and two or three hormones - human chorionic gonadotropin (hCG); unconjugated estriol; and sometimes, inhibin A.
The placenta will produce progesterone and estriol. These hormones will be crucial in the maintenance of your pregnancy. Tissue that will form your baby's bones is being laid down, especially around the head and limbs.
The triple screening measures the amounts of three substances in a pregnant woman's blood: alpha-fetoprotein (AFP), human chorionic gonadotropin (hCG), and estriol (uE3). When a test for the hormone inhibin A is added, it's called a quad screening.
This blood test for 4 biochemical markers, (AFP, HCG, estriol, DIA), has a detection rate of 75% - 80% for aneuploidy.
The three tests are MSAFP, beta-human chorionic gonadotropin, and unconjugated estriol. Each of these proteins are made and utilized by your unborn baby.

hCG - human chorionic gonadotropin hormone (a hormone produced by the placenta)
estriol - a hormone produced by the placenta.
inhibin - a hormone produced by the placenta.
The TT ("Triple Test")is similar to the MSAFP blood test, except that each measures two other substances in the blood of the mother -- beta hCG (human chorionic gonadotropin) and unconjugated estriol (also called E3, a form of estrogen).
- Free(beta)hCG or total hCG (human chorionic gonadotrophin)
- AFP (alpha fetoprotein)
- uE3 (unconjugated estriol)
Some also test for:
- Inhibin A.
The triple screen checks alpha-fetoprotein (AFP), human chorionic gonadotropin (hCG), and a type of estrogen (unconjugated estriol, or uE3). The quad screen checks these substances and the level of the hormone inhibin A.
The substances measured are alpha-fetoprotein (AFP), human chorionic gonadotropin (hCG), estriol (a form of estrogen) and inhibin-A. The last one, inhibin-A, is what makes this test "enhanced," since the routine triple screen does not include it.
Another crucial prenatal care procedure is the quad screen test, which examines the mother's blood for the following substances: AFP, hCG, Estriol, and Inhibin-A. The procedure assesses if the levels of these substances are high, low, or abnormal.
