You need to register to donate blood from a vein in pregnant women, this is done by screening (blood from a vein for infections, hormones, etc.) To undergo ultrasound diagnostics is also included in screening. No need to run and take a bunch of unnecessary tests. First, register and manage your pregnancy. It will be seen further. In the early stages, it is not possible to determine practically there by ultrasound - they look at the thickness of the collar space, the cervical attachment of the chorion, etc. (this is done up to 11 weeks - at this time they look where the pregnancy is in the uterus or not.) The second is 11 -20 weeks. ... look at the sex and anatomy here already more specifically, Downs are determined by the structure of the nasal bone, for example. Here you can’t list a lot of information. The main thing is to remember that you do not need to panic and run through hospitals headlong. Do everything in stages with your gynecologist and you will be fine.
I do not know if such a test is done in Russia, but in the USA and Australia it is usually suggested to conduct a non-invasive prenatal test (NIPT). For the test, blood is taken from the vein of a pregnant woman for more than 10 weeks. It contains fragments of the child's DNA, which are analyzed for abnormalities, various chromosomal syndromes.
Well, for example: go to Switzerland or Germany, with your husband, donate blood, an ounce of bone marrow, and a number of complex tests. After a while you are told that what "any person" can say, the probability of being said is no more than 20% within 4 months, in my opinion. I don’t know how they do it, but you’ll rather not like what you hear, but you will think about it and involuntarily program yourself, fear changes your body.
For me, Murphy's law works like a clock in our life , "What should happen will definitely happen"
In the formation of a predisposition to a particular disease, there are several risk factors, including genetic. Parents may have certain gene variants that increase the risk of specific diseases that they can pass on to their children.
Genetics Before conceiving a child, it is important to know your own carrier status of monogenic diseases. What does it mean? Each of us is a healthy carrier of about 10 such diseases. If future healthy mom and dad are carriers of the same mutation, they may have a sick child.
At the moment, any couple planning to have a child can undergo such an analysis for future parents. It is worth looking only for the most common and most severe genetic diseases, such as a hereditary form of breast cancer, cystic fibrosis, and periodic illness. Especially if the future parents belong to the same ethnic group or the marriage is closely related.
Infections It is also necessary to be screened for genital infections, as some of them can affect the fetal development of the baby, while others can be transmitted to the baby during natural childbirth.
Routine checkups Both parents-to-be should be careful about their own health and not ignore the annual check-ups, exercise regularly and eat a balanced diet. After all, the health of the new family member will depend on the health of the parents.
