Prenatal screening tests are non-invasive assessments done during pregnancy to check for certain genetic conditions, chromosomal abnormalities, and birth defects in the baby. These tests are not meant to diagnose, but to assess risk levels and help parents make informed decisions.
At Dr. Richa Gangwar’s antenatal care clinic in Lucknow, we believe that knowledge during pregnancy leads to peace of mind, early interventions, and better outcomes.

What Are Prenatal Screening Tests?
Prenatal screening tests are non-invasive assessments done during pregnancy to check for certain genetic conditions, chromosomal abnormalities, and birth defects in the baby. These tests are not meant to diagnose, but to assess risk levels and help parents make informed decisions.
At Dr. Richa Gangwar’s antenatal care clinic in Lucknow, we believe that knowledge during pregnancy leads to peace of mind, early interventions, and better outcomes.
Why Are These Tests Important?
The purpose of prenatal screenings is to:
- Detect potential health issues early in pregnancy
- Offer parents clarity and preparation
- Reduce the risk of complications through early planning
- Ensure the mother and baby are monitored more closely if needed
While most babies are born healthy, screening helps identify the few who may need extra care.
Types of Prenatal Screening Tests
🩺 1. First Trimester Screening (Week 11–13)
This includes:
- Nuchal translucency scan (ultrasound of baby’s neck thickness)
- Blood tests for hCG and PAPP-A hormones
It helps assess the risk of:
- Down syndrome (Trisomy 21)
- Trisomy 18 and 13
This test is safe, painless, and helps guide further testing if needed.
🧬 2. Second Trimester Screening (Quad Test, Week 15–20)
This blood test measures four key substances and screens for:
- Neural tube defects (like spina bifida)
- Chromosomal conditions
- Risk of preterm birth or low birth weight
It is often combined with first trimester screening to give a complete picture.
🔬 3. Non-Invasive Prenatal Testing (NIPT)
A highly accurate blood test that looks at fetal DNA fragments in the mother’s blood.
It screens for:
- Down syndrome
- Trisomy 13 and 18
- Sex chromosome abnormalities
NIPT is safe for both mother and baby, and usually done after 10 weeks of pregnancy.
🖥️ 4. Ultrasound Scans
Ultrasound scans are part of both screening and monitoring. Key scans include:
- Dating scan (6–9 weeks)
- NT scan (11–13 weeks)
- Anomaly scan (18–22 weeks) — checks organs, spine, limbs, and brain development
- Growth scans (third trimester)
These scans not only check for anomalies but also ensure the baby’s growth, heartbeat, and position are progressing well.
Are Screening Tests Safe?
Yes. All routine prenatal screening tests are non-invasive and safe for both the mother and the baby. They typically involve:
- A blood sample
- An ultrasound scan
- No radiation, needles into the womb, or discomfort
If any screening comes back as high risk, you will be offered diagnostic tests such as amniocentesis or chorionic villus sampling (CVS) — but only with your informed consent and counselling.
Do All Pregnant Women Need Screening?
Prenatal screening is offered to all pregnant women, but especially recommended if:
- You are over 35 years of age
- There is a family history of genetic disorders
- You’ve had a previous baby with a birth defect
- You have certain medical conditions
At Dr. Richa Gangwar’s clinic, we provide personalized screening advice based on your history and risk factors.
When Should You Talk to Your Doctor?
You should discuss screening options:
- At your first prenatal visit (around 6–9 weeks)
- Again during your 11–13 week appointment
- Anytime you feel uncertain or overwhelmed
We offer gentle, non-judgmental guidance, and help you understand results with clarity and emotional support.
