The increase in fluid indicates whether there is an increased risk of chromosomal abnormalities such as Down syndrome and congenital heart disease.

Blood Test:

After the ultrasound, blood analysis is done. PAPP-A (pregnancy-related plasma protein A) and hcG values ​​are checked. These are 2 hormones produced by the fetus and passed into the mother’s bloodstream. The values ​​obtained as a result of these analyzes are evaluated together with the NT measurement and the age of the mother. Thus, trisomy 21 and risk of trisomy 18 can be determined.

In addition, baby’s nasal bone measurement can be made during ultrasound. The baby’s lack of nasal bones may indicate a higher risk of Down syndrome.

It occurs when there are 2 copies of 21 chromosomes in the fetus, but it occurs when there are 3 copies.

Trisomy 18 is a problem caused by the presence of three 18 chromosomes. It causes deformation and mental retardation. Babies with this problem either die in the womb or in the first year after birth.
