What tests are carried out in multiple pregnancies
If you have a multiple pregnancy diagnosed, then you will be advised to visit your local gynecologist more often than pregnant women with a single fetus inside. Accordingly, the urine test you will take more often. The fact is that multiple pregnancies often occur with various complications. The load on the woman's body increases significantly, often causing toxicosis in the first trimester of pregnancy. The cardiovascular system also experiences overloads, and due to a more frequent enlargement of the uterus, internal organs - the heart, intestines, lungs and bladder - are tightened, causing shortness of breath, rapid fatigue, heart palpitations, urination and constipation.
Women with multiple pregnancies are more likely to suffer from preeclampsia, iron deficiency anemia, bleeding and premature detachment of the placenta.In addition, in multiple pregnancies, babies are more likely to be born with defects in the heart, brain, liver, and bladder. The risk of having children with cerebral palsy increases 4 times. Therefore, in the first place you must pass all tests and pass all examinations that women undergo singleton pregnancies. We are talking about a general analysis of blood, urine, triple hormonal test, analysis of blood for infections and hCG, ultrasound, and so on.
In the first trimester, you will be asked to conduct a test to measure the thickness of the collar space. Using this ultrasound, you can determine the amount of fluid under the skin of the back of the neck of all existing embryos and, based on this, diagnose Down syndrome. Surveys such as amniocentesis and chorionic villus biopsy are prescribed to detect chromosomal abnormalities and other malformations in two or more babies. Biopsy is performed at 10–12 weeks of pregnancy, and amniocentesis at 16–20 weeks. At the same time, the accuracy of both studies will depend on whether one embryo has an amniotic membrane or not. The fact is that one amniotic membrane means the same DNA structure, and in this case only one baby can be sampled. With different shells take a sample from each does not always work.
However, you should be aware that as a result of these studies, the risk of miscarriage increases. In addition, in the third trimester of pregnancy, you can be assigned cardiotocography, which allows to determine the heart activity of babies and dopplerography, which helps to assess blood flow in the uterus vessels, as well as the main vessels of the fetus and placenta. This examination will help identify fetal hypoxia and take steps to eliminate it.
