Non-invasive prenatal genetic determination of the child's blood of the mother's blood is a genetic laboratory diagnostic method that allows you to determine the field of fetus in the early pregnancy.
The sexual activity of the person at the level of the genotype is determined by a pair of so-called genital chromosomes. In women, a set of genital chromosomes consists of two x chromosomes, in men - from x and y chromosomes. Methods of genetic laboratory diagnostics, allowing to detect these chromosomes in human body cells, have been developed for a long time. But in relation to the task of the early genetic determination of the Far Future, another problem is added - obtaining material (cells, DNA fragments) of the fetus.
When conducting Eco, this problem is solved simply - the material for the study is taken directly from the test tube. But with a naturally occurring pregnancy, until recently, for solving this problem, only the so-called invasive methods of prenatal diagnostics (puncture of chorion and placenta needle under UZ-controls through the front abdominal wall of the future mother) were proposed. Since invasive diagnosis is accompanied by a significant discomfort for a pregnant woman and carries the probability of pregnancy interruption, in wide clinical practice, the early definition of sex of the child was rarely used.
In 1997, presence in the blood of pregnant extracellular DNA of the fetus, and three years later, the presence of circulating fruit DNA in the plasma was also proven. This discovery was the impetus for the development of early non-invasive prenatal diagnostics, including the definition of the Floor Floor. Thus, the early genetic determination of the Floor Floor is based on the identification of pregnant cells and DNA of the fetus, and the search for markers of the male Y-chromosome, which is not in girls.
Special preparation for research does not require. Everything you need for research is the venous blood of the mother. Blood for analysis is assembled into a special test tube, which guarantees the stability of fetal DNA in the plasma.
You can contact the Medical Center "Private Medical Practice" in order to determine the sex of the fetus from 16 weeks. The expert level of diagnosticity and the presence of progressive high-precision equipment allows you to do this. However, the general rule sounds as follows - the more the term of pregnancy, the more accurate one can determine who the future mother does not wear out.
