Non-invasive prenatal test (NIPT)
During pregnancy, it is essential to monitor not only the general health of the mother but also the development of the fetus. Minimizing any risk of giving birth to a sick child and identify possible anomalies, chromosomal, and hereditary diseases at an early stage, pregnant women undergo what is called prenatal diagnosis.
The Non-Invasive Prenatal Test (NIPT) is a screening study aimed at determining the most common fetal chromosomal abnormalities that can lead to malformations, retarded psychomotor development, and social maladjustment of the baby.
The test is performed on a woman’s blood sample from the 10th week of pregnancy, which avoids invasive procedures (amniocentesis, chorionic biopsy, cordocentesis). The test is possible, whether a single pregnancy or twins.
How does it happen?
NIPT consists of a blood sample from the mother along with a DNA test of the fetus. The examination reveals the presence of abnormal chromosome numbers (aneuploidy) in the fetus. Aneuploidies are the causes of congenital genetic diseases in children, which can have a significant impact on their physical health and mental capacities.
The screening (test) is recommended if there is an increased risk of fetal chromosomal abnormalities as an additional method for the following indications:
- The age of the pregnant woman – 35 years and over for a single pregnancy or 32 years and over for twins;
- The presence in the family of a child (fetus) suffering from a chromosomal disease;
- Detection of a delay or anomaly in the development of the fetus during an ultrasound;
- The high risk of chromosomal abnormalities due to family history.
