The triple screening in pregnancy is a test that your gynecologist will carry out using two tools: a blood sample (between weeks 8-10) and an ultrasound (week 12). The purpose of this test is to obtain the risk index for the baby to have certain chromosomal abnormalities.
The way to do it is through a mathematical calculation, which is obtained by entering the results of the maternal analysis, her weight, ethnicity and other data in the software indicated for it. The most frequent alterations that are looked for are chromosomal alterations such as trisomy 21 (Down syndrome), trisomy 18 (Edwards syndrome) and neural tube defects.
