What Is an NIPT Test?

NIPT stands for noninvasive prenatal testing. It is also called cell-free DNA screening or cfDNA screening.

The test commonly screens for:

• Down syndrome, or trisomy 21
• Edwards syndrome, or trisomy 18
• Patau syndrome, or trisomy 13
• Sex chromosome differences in some test panels

Expanded panels may screen for additional conditions, but their accuracy and clinical usefulness can vary.

Is NIPT a Diagnostic Test?

No. NIPT is a highly accurate screening test for common chromosomal conditions, but it cannot provide a definitive diagnosis.

A high-risk result does not confirm that the fetus has a chromosomal condition. Diagnostic testing, such as chorionic villus sampling or amniocentesis, may be recommended before making pregnancy-related medical decisions.

Who May Consider NIPT?

NIPT may be considered by pregnant patients who:

• Want early chromosomal screening
• Are of advanced maternal age
• Have abnormal first-trimester screening results
• Have concerning ultrasound findings
• Previously had a pregnancy affected by a chromosomal condition
• Became pregnant through fertility treatment
• Prefer more accurate screening for common trisomies

Suitability may differ for twins, multiple pregnancies, egg-donor pregnancies, or pregnancies involving a vanishing twin.

How Is the Test Performed?

The NIPT process typically includes:

1. An OB-GYN consultation
2. Confirmation of gestational age
3. Maternal blood collection
4. Laboratory analysis of cell-free DNA
5. Medical interpretation of the results
6. Follow-up recommendations when necessary

No needle enters the uterus, so the blood test itself does not carry the procedure-related miscarriage risk associated with invasive diagnostic testing.

Understanding NIPT Results

Results are generally reported as low risk, high risk, or inconclusive.

• Low risk: The screened conditions are less likely but cannot be completely excluded.
• High risk: Further counseling and diagnostic testing may be recommended.
• Inconclusive: There may not be enough fetal DNA in the sample, and repeat testing or another screening method may be needed.

Results should be reviewed with an OB-GYN rather than interpreted independently.

NIPT and Prenatal Ultrasound

NIPT does not replace prenatal ultrasound. Ultrasound can evaluate fetal growth, anatomy, placental position, and structural conditions that NIPT cannot detect.

Patients should continue routine prenatal checkups and medically recommended ultrasound examinations even after receiving a low-risk result.

NIPT Testing for Foreigners in Busan

International patients can arrange NIPT through private OB-GYN clinics, maternity hospitals, and university hospitals around Seomyeon, Haeundae, Centum City, Gwangalli, and other Busan areas.

Before booking, ask about:

• Available NIPT brands and screening panels
• Appropriate timing for testing
• Total test and consultation fees
• Korean insurance eligibility
• English-speaking consultations
• English laboratory reports
• Genetic counseling after high-risk results
• Expected result turnaround time

Availability and pricing can vary among providers.

Preparing for Your NIPT Appointment

Bring:

• Passport or Korean identification
• Estimated due date
• Previous ultrasound reports
• Prenatal screening results
• Fertility-treatment records
• Personal and family medical history
• Information about twins or a vanishing twin

Fasting is generally unnecessary, but follow the clinic’s instructions.

Frequently Asked Questions

How early can NIPT be performed?
It is commonly available from approximately 10 weeks, although the exact timing depends on the laboratory and pregnancy.

Can NIPT confirm Down syndrome?
No. A high-risk result should be confirmed through diagnostic testing.

Can NIPT determine fetal sex?
Some panels include fetal-sex information. Availability and reporting policies vary.

What happens if the result is inconclusive?
The provider may recommend repeating NIPT, having an ultrasound, using another screening method, or considering diagnostic testing.

Is NIPT suitable for twins?
Some NIPT panels can screen twin pregnancies, but limitations and accuracy may differ from singleton pregnancies.
