What is Prenatal Screening?

Early Insight for a Healthy Pregnancy

Most pregnant women can expect to have a healthy pregnancy and baby. However, it is estimated that 1 in 1000 pregnancies will have a congenital defect like Down Syndrome which affects physical development, learning, and sometimes the heart or other organs. Such genetic disorder cannot be diagnosed by ultrasound alone.
The risk increases with maternal age (about 1 in 250 for women over 35), yet most babies with Down Syndrome are born to younger mothers.

Prenatal screening is a test that offers a safe and reliable way to understand these risks early in pregnancy.

Early screening empowers parents with timely information and choices.

Types of Prenatal Screening

Double/Triple Marker Screening OR Traditional Prenatal Screening :
It involves:

Results are analyzed using advanced software to calculate the chance of genetic defects. If the risk is high, further confirmatory testing i.e. Prenatal Diagnostic test is offered.

Non-Invasive Prenatal Screening (NIPS)

NIPS is a simple test which used mothers blood to analyses tiny fragments of the baby’s DNA (cell-free DNA) circulating in the mother’s blood. It provides early and highly accurate screening for certain chromosomal conditions, without any risk to mother or baby.

The NIPS Test uses whole genome sequencing approach that reads thousands of genes.

Sequences to ensure comprehensive coverage with more than 99% accuracy.

What NIPS screens for:

Trisomy 21 (Down Syndrome)Trisomy 18 (Edwards Syndrome)
Trisomy 13 (Patau Syndrome)
Sex chromosome conditions such as Monosomy X (Turner Syndrome) and other aneuploidies
Selected microdeletions, such as 22q11.2 deletion syndrome

When it can be done:

From as early as 10 weeks of pregnancy, Recommended up to 22 weeks of gestation
Suitable for women across different age and risk categories

Why choose NIPS?

It is safe, non-invasive, and offers early reassurance by detecting conditions with high accuracy, helping parents make informed choices about their pregnancy.

Feature NIPS Traditional Screening
🧪 Test Type Simple blood test (analyzes baby’s DNA) Blood test + ultrasound markers
📅 When Done From 10 weeks 11–14 weeks
🎯 Accuracy Very high (>99% for Down Syndrome) Moderate (70–80%)
🤰 Safety No risk to mother or baby Safe, but less accurate
🧬 Conditions Screened Trisomy 21, 18, 13, sex chromosome disorders, some microdeletions Trisomy 21, 18, 13
Next Steps High-risk → confirm with diagnostic test High-risk → confirm with diagnostic test

Prenatal Diagnostics

Prenatal diagnostics tests are offered to the pregnant women with high-risk prenatal screening results, to provide accurate information about a baby’s health before birth, helping parents and doctors make informed decisions.

Why it matters

Prenatal diagnostic tests go beyond routine screening. They are designed to confirm or rule out chromosomal or genetic conditions when screening results or medical history indicate a higher risk.

Commonly Diagnosed Conditions

Chromosomal abnormalities (e.g., Down Syndrome, Edwards Syndrome, Patau Syndrome)
Genetic disorders (such as Thalassemia, Sickle Cell Disease, Cystic Fibrosis)
Structural anomalies (heart defects, neural tube defects, etc.)
