What is fetal fibronectin?

Fetal fibronectin is a protein that plays an essential role in pregnancy. This protein, which is produced by fetal cells, is used to bind the fetal membrane and the lining of the uterus. Protein is also a useful diagnostic marker for premature delivery, as the fetal fibronectin test can effectively determine whether a woman is likely to transfer her pregnancy. The cell adhesion process describes how certain types of cells "stick" to other types of cells or tissues. This feature of this protein is what a protein is important in fetal development. Fetal fibronectin is produced in the uterus and helps chorions, fetal membranes and decidua, uterine lining, holds together. This allows the fetus to be kept safely inside the uterus.

Fibronectin produced by fetal cells can be detected in the vagina on the certain phase of pregnancy. Up to 22 weeks it is possible to detect fibronectin in the vagina. After this point, the level of fibron in the vagina begins to decrease. 24 weeks is not fibronectin during a healthy pregnancyOMEN in the vagina and protein levels do not start to increase again up to 34 weeks. This formula of fibronectin secretion causes fetal fibronectin to test the exact way of determining whether a woman is endangered by premature birth.

When a woman is close to the end of her pregnancy, fibronectin inside the uterus begins to crumble, as part of the body preparation for childbirth. When this happens, fibronectin can be detected in the vagina. In a typical pregnancy, this occurs in 34 weeks or later; If a woman is endangered by premature birth, fibronectin may be detected in the vagina before a 34 -week mark.

One important thing to note is that the posititest of fetal fibronectin does not necessarily mean that a woman gives birth prematurely. It is simply a degree of risk: women who test positive are exposed to an increased risk of premature birth. Yet the test is useful because it allows a woman, herThe family and its healthcare providers prepare for the possibility.

Another useful aspect of the test is that it can help to predict whether a woman with symptoms of premature work is truly at risk of delivering her child soon. This is important because many women with such symptoms continue to transmit pregnancy. The fibronectin test helps to distinguish between women whose symptoms indicate a high level of risk, and women whose symptoms indicate a low level of risk, and this is the only way to distinguish between the two categories.
