| Abstract | |
| Screening for aneuploidies in the first and second trimester of pregnancy is an important aspect of prenatal testing. The overall prevalence of aneuploidy is around 1 in 228 (0.4%). First trimester screening has proved effective in identifying aneuploid fetuses, the definitive diagnostic test for aneuploidy available in first trimester is chorion villous sampling (CVS). | |
