Chromosomal abnormality screening, also known as prenatal genetic screening or prenatal testing, is a medical evaluation performed during pregnancy to assess the risk of certain chromosomal abnormalities or genetic conditions in the developing fetus. These tests help to identify the likelihood of the baby having specific genetic disorders and provide information to expectant parents for making informed decisions about their pregnancy and healthcare.

There are different types of chromosomal abnormality screening tests, including:

Non-Invasive Prenatal Testing (NIPT): This blood test analyzes the fetal DNA present in the mother’s blood to screen for chromosomal abnormalities, such as Down syndrome, trisomy 18, and trisomy 13.

First Trimester Screening: A combination of ultrasound and blood tests that assess the risk of chromosomal disorders and certain birth defects.

Second Trimester Screening: Blood tests performed later in pregnancy to identify the risk of chromosomal abnormalities and neural tube defects.

It is essential for expectant parents to have access to information about chromosomal abnormality screening, as it allows them to make informed decisions about their pregnancy and, if necessary, pursue further diagnostic testing or prepare for the potential care needs of the baby after birth.
