Prenatal care is a set of tests that are carried out before and during pregnancy in order to ensure a smooth, safe pregnancy and a healthy, full-term baby.
It includes prognostic and diagnostic tests, such as the measurement of biochemical indicators (PAPP-a and β-hCG in the first trimester of pregnancy) and the Nuchal translucency (NT) which study and analyse both the course of pregnancy in the mother's body and the fetus’ genetic material.
Prenatal screening tests identify the risk or likelihood of a particular risk. When the results of a test are positive, prenatal screening diagnostic tests can provide a definitive answer.
In our laboratory we apply the most advanced tests with emphasis on safety for mother and baby and our experienced and specially trained staff are at your disposal to answer any relevant question.
A general laboratory check is carried out which includes:
10th – 11th week (1st trimester)
An investigation is carried out to statistically assess the risk for chromosomal abnormalities (Down syndrome, etc.). The realization of this investigation concerns the combined assessment of:
- PAPP-a, which is the protein of the placenta and its value is calculated in the pregnant woman's blood
- Beta-Human Chorionic Gonadotropin (beta-HCG)
- Nuchal translucency (NT)
15th - 19th week (2nd trimester)
In order to identify possible malformations or serious chromosomal abnormalities, the a-test or triple test or 2nd trimester prenatal checkup is performed. Screening tests can indicate the possibility of fetal abnormalities such as trisomy 21 (Down syndrome) and trisomy 18.
In this triple test, three indicators are measured.
- β-hCG hormone, which is produced by the placenta
- aFP, which is produced in the amniotic sac and fetal liver
- Unconjugated (free) estriol, which is also produced by the placenta
