Down’s syndrome screening is better done around 16 weeks of pregnancy and no later than 20 weeks.
Down’s syndrome screening, which can be performed by ultrasound or serum biochemistry or chorionic villus puncture for chromosomal testing, is a relatively safe, non-invasive test that is commonly used to check for abnormalities of trisomy 21-trisomy, trisomy 18-trisomy, and trisomy 13-trisomy.
Down’s syndrome screening is a very important screening program. It analyzes and examines the chromosomes of the reproductive system cells in the embryo in order to perform later diagnostic tests. The purpose of the screening is not to diagnose a disease, but to determine whether there is a possibility of a disease and thus whether it is necessary to continue the pregnancy.
It is important for pregnant women to undergo the appropriate obstetrical tests on a regular basis in order to achieve eugenic fertility. It is advisable to consult a specialized doctor for details.
