In the prenatal check performed by the obstetrician or gynecologist, different tests can be done. This is different for every woman and depends, among other things, on the age of the mother. We will put these studies in a row for you.
Prenatal literally means "before birth". Prenatal control is therefore all tests for the birth of the baby. The development of the baby (= prenatal development) in the abdomen is thus controlled during these studies.
Prenatal control: The term echo
In the term echo, between 8 and 12 weeks of pregnancy, measurements of, inter alia, head-breech length and measurements of bones and other structures will calculate an accurate duration ("term") of the pregnancy. With this, the calculated date can be calculated accurately.
Naturally, heart action can also be determined in the child and the place of the placenta is determined. Heart action is nothing but the beating of the heart of your baby, this is visible from 28 days after fertilization. The doctor can also see if there is a multiple person during this term ultrasound. This examination is generally reimbursed by the health insurer if you have insured your pregnancy.
At home to listen to the heartbeat of your unborn baby? That is possible with this Angelsounds Doppler.
To be able to carry out the term ultrasound, it is important that you come with a full bladder. This can be quite difficult for pregnant women. But make sure you have not peed for 2 to 4 hours beforehand and drink an extra glass of water before you go inside. In this way the ultrasound operator can see the easiest way to see your child in the abdomen.
Prenatal control: Neck fold measurement
The neck fold measurement is an ultrasound examination of the fetus in weeks 11 to 14 of the pregnancy where the thickness of the neck fold is measured. A thickened fold of the neck can indicate a chromosomal aberration, of which Down's syndrome is the most common.
The neck fold measurement indicates only a risk. When a thickened neck fold is determined, a chorionic test or amniocentesis will be required to make a definitive diagnosis.
The neck fold measurement is sometimes combined with the triple test to arrive at a more accurate risk assessment.
Prenatal control: Flocculation test
In a chorionic test some chorionvilli is taken. These are small protrusions of the placenta. The research is usually carried out between the 11th and the 14th week of pregnancy, in order to detect disorders in the fetus.
Performing a chorionic test instead of amniocentesis has the advantage that the rash is known much earlier in pregnancy. In case of a deviation, action can then be taken more quickly and in a normal examination the parents are reassured earlier.
A chorionic test can be performed via the cervix or via the abdominal wall. Both methods are done under guidance of an ultrasound. The procedure involves a risk of miscarriage just as with amniocentesis. This probability is 3 to 5 out of 1,000 studies.
Prenatal control: Amniotic puncture
With an amniocentesis almost always research is done on the chromosomes.
The amniotic fluid is removed via the abdominal wall. This is done with a needle and just as with the chorionic test using ultrasound. Approximately 15 to 20 ml of amniotic fluid is sucked up. The amniocentesis is done after the 15th week of pregnancy.
Just as with the chorionic test, there is a risk of miscarriage. This occurs in 3 - 5 of the 1000 studies.
20 weeks Echo
Around the 20 weeks of pregnancy, every woman gets the opportunity to have a structural screening ultrasound. This is not mandatory but is reimbursed by the health insurer. A screening ultrasound is an ultrasound that looks at the growth and development of the fetus. So it is checked if everything is going well and early congenital abnormalities can be detected.
On this screening echo, for example, it is checked whether a child has cleft (lip fissure), open back or clubfoot. We also check whether the heart, blood vessels and other organs have been properly constructed.
Although it is possible to terminate a pregnancy if a birth defect is observed, it is not the main reason why this ultrasound is done. It is especially important for parents and doctors to know in advance if something is not right with the baby. This to make the right medical and mental preparations.
