- - regular monitoring at the obstetrician-gynecologist.
During pregnancy, try to take timely ultrasonography (US).It is recommended that a minimum of three treatments during pregnancy - at 11-14, 20-24 and 30-34 weeks of midwifery.There are several signs that may indicate the presence of a chromosomal pathology fetus : increase of nuchal translucency, fast or slow heartbeat, irregularities in the structure of the heart is too small size of the maxilla, and many others.These signs do not mean that there fetal genetic abnormalities, but the results of ultrasound should pay
Along with ultrasound in the first and second trimesters of pregnancy turn in screening blood tests.These studies take into account the different levels of the factors in serum and other indicators, such as maternal age, the presence of harmful habits, weight, performance ultrasound fetal .From the lab results come in the form of calculated probability the presence of certain abnormalities in the genome.At high values discuss with your doctor the need for surveys with greater accuracy.
If you suspect the presence of abnormalities in the fetus you can go through the procedure of chorionic villus sampling, or cordocentesis amnio-.All of these tests are aimed at an immediate investigation of the chromosomes of the fetus and identification of certain genetic abnormalities.The validity of this procedure is quite high.Fencing material for analysis occurs at the very fetus , of the membranes (amniocentesis), the umbilical cord (cordocentesis) or placental villi.Since this happens anyway damage the embryo membranes, increased risk of spontaneous abortion: it is necessary to consider when making a decision.
In these studies, both ultrasound and screening for serum markers, there is a sufficiently high probability of an error, it is recommended to re-examination.It is advisable to use the services of the different laboratories and specialists.Anyway, to conclude that the presence of abnormalities in the fetus only on these indicators is not necessary.
