For any future mother, there is a natural desire toher baby was healthy. Therefore she cares so much for the unborn baby. Therefore, there are so many tests and examinations. To each pregnant woman, doctors prescribe a special analysis - screening. It consists of ultrasound and blood tests for specific proteins and hormones. It is aimed at revealing the chromosomal diseases of the fetus at the earliest stages.
Therefore, if the doctor has appointed a biochemicalscreening, you do not need to fear it and fear that the child will have Down syndrome. The examination is aimed precisely at excluding the risk of this and other diseases. Biochemical screening is carried out in the first trimester for a period of 10-14 weeks and in the second trimester for a period of 16 to 18 weeks. In the third trimester, as a rule, only ultrasonic screening is performed.
Most expectant mothers know that pregnancycan be determined by the presence in the blood of the hormone hCG. The same hormone testifies to the correct or incorrect development of the fetus. The thing is that for every term of pregnancy there are norms of its content in the body. By deviations from normal indicators, one can judge the risk of any pathologies. It is the amount of hCG that determines the biochemical screening of the first trimester.
Biochemical screening in the second trimesteradds to the study the hormones of the placenta and the liver of a growing child - free estriol and alfa-fetoprotein. Based on the results obtained, it is also possible to judge the presence of chromosomal diseases, developmental disorders due to viral diseases, intrauterine infections, the risk of miscarriage. But we will remind that only a geneticist can give a correct assessment of the situation. Even an observing obstetrician-gynecologist is not always able to draw accurate conclusions. Perhaps the deviation from the norm is caused by the condition of the future mother, who should pay attention to the health of the kidneys or liver.
In addition to screening for pregnant women,screening of newborns. This analysis is mandatory for all children born and has a preventive nature. The study helps determine the presence of hereditary diseases. After all, early detection of the disease simplifies its treatment. Therefore, if the expectant mother doubts whether it is worth to go through biochemical screening, there can be only one answer - definitely, it's worth it. This will help to avoid many problems and keep the nerve cells intact - they will still be needed when raising a beloved child.
