Estriol Unconjugated
About Test
The Estriol Unconjugated (E3) test is a laboratory test used to monitor the levels of the hormone estriol in a pregnant woman's blood. Estriol is one of the three main estrogens produced by the body and is produced in increased quantities during pregnancy. The levels of estriol in a pregnant woman's blood can provide important information about the health of the pregnancy and the development of the fetus.
The Estriol Unconjugated test measures the levels of unconjugated estriol, which is the form of estriol that is not bound to other substances in the blood. The levels of unconjugated estriol can provide important information about the function of the placenta, which is the organ that supplies the fetus with nutrients and oxygen during pregnancy.
The Estriol Unconjugated test is usually done as part of a series of tests known as maternal serum screening, which are used to screen for certain birth defects and chromosomal abnormalities in the fetus. The results of the test, along with the results of other tests such as the alpha-fetoprotein (AFP) test and the human chorionic gonadotropin (hCG) test, can provide important information about the health of the pregnancy and the development of the fetus.
The results of the Estriol Unconjugated test, along with a woman's clinical symptoms and other factors, can help healthcare providers diagnose and manage certain pregnancy-related conditions and make informed decisions about the best course of treatment for both the woman and the fetus.
