Genetic Screening in Pregnancy: When and Why It’s Done
Ensuring a Healthy Start with Expert Prenatal Care at Motherly Hospital
Pregnancy is a wonderful journey, but it also raises many questions and concerns about the health of your baby. One important aspect of prenatal care is genetic screening — a set of tests that help identify the risk of your baby having certain genetic or chromosomal conditions.
At Motherly Hospital, we provide comprehensive genetic screening to support parents with timely information and expert guidance. Here’s everything you need to know about when and why genetic screening is done during pregnancy.
What is Genetic Screening?
Genetic screening is a series of tests performed during pregnancy to assess the likelihood that a baby might have genetic disorders such as Down syndrome, Edwards syndrome, or other chromosomal abnormalities. Unlike diagnostic tests, which can confirm a condition, screening tests estimate risk and help decide if further testing is needed.
When is Genetic Screening Done?
Genetic screening typically takes place during specific windows in pregnancy:
- First Trimester Screening (11-14 weeks) : This includes a blood test and an ultrasound measurement called the nuchal translucency scan. It evaluates the risk for conditions like Down syndrome and Trisomy 18.
- Second Trimester Screening (15-20 weeks) : Also called the quad screen, this blood test measures four substances in the mother’s blood to assess risks of chromosomal abnormalities and neural tube defects.
- Non-Invasive Prenatal Testing (NIPT) : From around 10 weeks of pregnancy, this advanced blood test analyzes fetal DNA circulating in the mother’s bloodstream. It offers highly accurate screening for certain genetic conditions with no risk to the baby.
Who Should Consider Genetic Screening?
Genetic screening is recommended for:
- Women aged 35 years or older
- Those with a family history of genetic conditions
- Previous pregnancies affected by genetic disorders
- Abnormal ultrasound findings during pregnancy
- Couples who are carriers of genetic conditions
- Parents seeking detailed knowledge about their baby’s health
What Happens After Screening?
- Low-risk results: Routine prenatal care continues with standard monitoring.
- High-risk results: Additional diagnostic tests like amniocentesis or chorionic villus sampling (CVS) may be suggested to confirm the diagnosis.
- Genetic counseling is provided to help parents understand the results and make informed decisions.
Is Genetic Screening Safe?
Yes, genetic screening is safe and non-invasive. It typically involves blood tests and ultrasound scans, which pose no harm to mother or baby. Diagnostic tests like amniocentesis do carry a small risk and are only done if screening indicates a need.
