Non Invasive Prenatal Screening

About this test

NIPT is an advanced prenatal screening test that analyzes small fragments of fetal DNA circulating in the mother’s blood. The NIPT is typically performed after 10 weeks of pregnancy and is highly accurate in assessing the risk of chromosomal conditions such as Down syndrome (Trisomy 21), Trisomy 18, and Trisomy 13.

Unlike traditional screening methods, NIPT uses next-generation sequencing technology to provide a more precise risk assessment. The NIPT s non-invasive, requiring only a maternal blood sample, making it safe for both mother and baby.

The NIPT is increasingly recommended as a primary screening option due to its high sensitivity and specificity. It can also detect sex chromosome abnormalities and, in some panels, microdeletions. However, the NIPT remains a screening test and not a diagnostic test.

Key points:

• Performed after 10 weeks of pregnancy
• Uses fetal DNA from maternal blood
• High accuracy for chromosomal abnormalities
• Non-invasive and safe
• May detect additional genetic conditions

Why consider this test?

NIPT is considered one of the most reliable screening tests for chromosomal abnormalities. The) significantly reduces the need for invasive diagnostic procedures like amniocentesis, especially in low-risk pregnancies.

Expecting parents may choose for early reassurance or to identify potential risks at an early stage. NIPT is particularly useful when combined with other clinical findings.

Key reasons:

• High detection accuracy
• Early screening option
• Reduces need for invasive tests
• Provides peace of mind
• Helps guide further decisions

Who should get tested?

NIPT is suitable for all pregnant women but is especially recommended for high-risk groups. Women above 35 years, those with abnormal first trimester screening results, or a history of chromosomal abnormalities are strong candidates for NIPT.

Doctors may also recommend NIPT in IVF pregnancies or when ultrasound findings raise concern. NIPT is widely accepted as a reliable screening tool.

Recommended for:

• All pregnant women after 10 weeks
• Women above 35 years
• Abnormal Double Marker results
• IVF pregnancies
• Family history of genetic disorders

More Information

NIPT requires no special preparation and involves a simple blood draw. Results of NIPT are usually available within 5–10 days and are reported as low-risk or high-risk categories.

While NIPT is highly accurate, positive results should be confirmed with diagnostic tests. NIPT does not pose any risk to the fetus, making it a preferred option for early screening.

Additional details:

• No fasting required
• Quick and safe procedure
• Results in 5–10 days
• Screening, not diagnostic
• Follow-up testing may be needed
