Scans during your pregnancy

For each pregnancy, three ultrasound scans will be reimbursed, one for each trimester. Various aspects are checked during these ultrasound scans:

12 weeks of pregnancy

18-22 weeks of pregnancy32 weeks of pregnancy
Growth and development of the childExtensive examination of all body parts of the babyChecking growth and position of the baby and the amniotic fluid volume
Nuchal translucency measurement and NIPT: screening for potential disorders such as Down’s Syndrome.Screening for serious anomalies

Chromosomes and chromosomal abnormalities

What are chromosomes?

Chromosomes are the carriers of our genetic material. There are 46 chromosomes in each cell of our body. These chromosomes are arranged in pairs, with a total of 23 pairs. In each pair, one chromosome comes from the mother and one from the father. The first 22 pairs of chromosomes are the same in men and women. Only the 23rd pair, the sex chromosomes, is different in men and women: a woman has two X chromosomes, a man has one X and one Y chromosome.

The reproductive cells, especially the egg cells and the sperm cells, are produced after a special division (meiosis) and contain only 23 chromosomes. When an egg cell is fertilised by a sperm cell, a new cell (the first fertilised egg cell) with 46 chromosomes is produced. Sometimes something goes wrong during this division process. If this happens, the baby may have one too many (trisomy) or one too few (monosomy) chromosomes. Usually the pregnancy ends spontaneously in a miscarriage before the twelfth week. However, it is also possible that no miscarriage occurs, but that a baby is born with a chromosomal abnormality.

Other problems can also occur during fertilisation, resulting in there being too many or too little smaller pieces of chromosomes in the foetus.

Screening for anomalies

The vast majority of children that are born here are completely healthy. Are there any congenital abnormalities in your own close family? Make sure you let your physician know as soon as possible, and preferably before you intend to become pregnant. That way, we can investigate whether it will be useful to take certain steps during your pregnancy. However, be aware that although medical science has made great progress in screening for anomalies, no test exists that gives you a 100% guarantee of a healthy child.

We carry out the following tests to screen for potential anomalies:
