Early diagnosis of pathologies of the fetus with each passing year becomes more and more reliable. It is carried out as a public women's consultation in the framework of compulsory health insurance and private clinics. When such risk factors as hereditary diseases among relatives or age pregnant over forty years, the question of the exclusion of the presence of pathologies of a fetus should be treated particularly seriously.

1. During pregnancy try time pass ultrasonography (us). At a minimum we recommend three treatments during pregnancy at 11-14, 20-24 and 30-34 weeks obstetric. There are several signs, which may indicate the presence of chromosomal pathology in fetus: increased nuchal translucency, fast or slow heartbeat, abnormalities in the structure of the heart, too small size of the maxillary bones, and many others. These signs do not mean that the fetus has a genetic disorder, but those results ultrasound is attentive to the issue of appointment of additional surveys.
2. Simultaneously with the ultrasound in the first and second trimesters of pregnancy pass a screening blood tests. In the course of these studies takes into account the levels of various factors in serum and other indicators, such as maternal age, presence of harmful habits, weight, indicators ultrasound of the fetus. From the lab results come in the form of calculated probability of the presence of certain abnormalities in the genome. At high values, discuss with your doctor the need for surveys with greater accuracy.
3. If you suspect the presence of abnormalities of the fetus , you can go through the procedure of chorionic villus sampling, amnio -, or cordocentesis. All these tests aimed at the direct study of the chromosomes of the fetus and detection of certain genetic abnormalities. The accuracy of this procedure is quite high. The fence material for analysis occurs in the fetus, from the amniotic SAC (amniocentesis), umbilical cord (cordocentesis) or villus of the placenta. Because it anyway there is damage to the membranes of the embryo, increases the risk of spontaneous abortion: it should take into account when making decisions.
