Treatment Overview
Early Fetal DNA Cell-free Screening, also known as Non-Invasive Prenatal Testing (NIPT), is a revolutionary genetic test that analyzes small fragments of fetal DNA circulating naturally in the mother’s blood. This test detects common chromosomal abnormalities, such as Down syndrome (Trisomy 21), Edwards syndrome (Trisomy 18), and Patau syndrome (Trisomy 13), as early as 10 weeks of pregnancy.
In Korea, advanced women’s hospitals and diagnostic centers use next-generation sequencing (NGS) and AI-based genetic analysis systems to deliver highly accurate and safe results. The screening is completely non-invasive, requiring only a simple maternal blood sample, and has an accuracy rate exceeding 99% for major chromosomal abnormalities.
Korea is internationally recognized for its precision in prenatal genetic testing, offering a blend of medical excellence, cutting-edge laboratory technology, and compassionate maternal-fetal care.
Purpose & Benefits
Purpose:
- To detect chromosomal aneuploidies such as Trisomy 21, 18, and 13.
- To identify sex chromosome abnormalities (Turner, Klinefelter, and related syndromes).
- To determine fetal sex, if desired by the parents.
- To provide early reassurance of fetal genetic health.
- To minimize the need for invasive testing procedures like amniocentesis.
Benefits:
- Highly accurate: Sensitivity above 99% for major chromosomal conditions.
- Safe and non-invasive: Requires only a maternal blood draw.
- Early detection: Can be performed from the 10th week of pregnancy.
- No risk to the fetus: Eliminates the risk of miscarriage associated with invasive diagnostic methods.
- Quick results: Korean laboratories typically deliver results within 5–10 days.
- Comprehensive peace of mind: Enables early, informed pregnancy management.
Ideal Candidates
Early Fetal DNA Cell-free Screening is recommended for all expectant mothers, especially those who:
- Are aged 35 or older at the time of conception.
- Have abnormal ultrasound or blood screening results.
- Have a family history of chromosomal disorders.
- Have experienced previous pregnancy complications related to genetic abnormalities.
- Conceived through IVF or assisted reproductive technology (ART).
- Carry multiple pregnancies (twins), depending on test type availability.
- Seek a non-invasive and accurate screening method early in pregnancy.
Possible Risks & Considerations
- The test is completely safe, with no physical risk to the mother or fetus.
- Inconclusive results may occur if fetal DNA levels are too low, requiring a repeat test.
- False positives or negatives are rare but possible; abnormal results require confirmation through diagnostic tests such as amniocentesis or chorionic villus sampling (CVS).
- Maternal health factors, such as obesity or certain medical conditions, can affect fetal DNA fraction in the bloodstream.
Korean hospitals ensure test accuracy through stringent quality control, expert analysis, and follow-up counseling when needed.
Medical & Diagnostic Techniques Used in Korea
Korea’s genetic testing laboratories use advanced molecular technologies and AI-assisted bioinformatics platforms for precise and reliable analysis of cell-free fetal DNA (cfDNA).
Key Diagnostic Methods Include:
- Next-Generation Sequencing (NGS): Decodes millions of cfDNA fragments to identify chromosomal abnormalities.
- Massively Parallel Sequencing (MPS): Allows simultaneous analysis of multiple chromosomes.
- AI-Based Genetic Algorithms: Korean laboratories use artificial intelligence to interpret sequencing data with exceptional accuracy.
- Maternal-Fetal DNA Fraction Analysis: Determines the percentage of fetal DNA in maternal blood to ensure validity.
- Extended Chromosomal Panels: Includes optional testing for microdeletions and sex chromosome abnormalities.
- Targeted Sequencing Panels: Tailored for specific populations or conditions for enhanced precision.
- Automated Bioinformatics Pipelines: Streamline data analysis for fast and reproducible results.
These technologies ensure world-class genetic accuracy and reliability in Korea’s early fetal DNA screening programs.
Recovery & Aftercare
- No downtime: The screening is non-invasive and painless.
- Quick turnaround: Results are available within one to two weeks.
- Follow-up care: In case of positive or uncertain results, obstetricians provide diagnostic testing options such as CVS or amniocentesis.
- Genetic counseling: Expectant parents receive expert consultation to understand results and plan next steps.
- Continuous monitoring: Korean hospitals integrate genetic results into ongoing prenatal check-ups for coordinated maternal-fetal care.
Patient comfort, confidentiality, and psychological support are key priorities in Korea’s prenatal testing services.
Results & Longevity
- High precision: Identifies fetal chromosomal abnormalities with superior accuracy.
- Early insight: Provides genetic information long before mid-pregnancy anomaly scans.
- Reduced invasive testing: Minimizes need for diagnostic procedures like amniocentesis.
- Peace of mind: Empowers parents with reassurance and clarity early in pregnancy.
- Foundational genetic record: Results remain valid throughout the pregnancy and can guide delivery and neonatal care decisions.
Korean genetic laboratories maintain rigorous standards, ensuring long-term reliability and patient trust in test outcomes.
Procedure Process in Korea
1. Pre-Test Consultation
The obstetrician or genetic counselor explains the test purpose, scope, and limitations, reviewing any prior prenatal screening results.
2. Blood Sample Collection
A small blood sample is drawn from the mother’s arm. The test is safe, requiring no fasting or special preparation.
3. DNA Extraction & Sequencing
Fetal cell-free DNA (cfDNA) is isolated from maternal plasma and analyzed using advanced sequencing technology to identify chromosomal irregularities.
4. Bioinformatics & Interpretation
AI-driven bioinformatics systems evaluate DNA fragments, comparing them with reference genomic data to detect abnormalities.
5. Results & Counseling
Results are discussed with the expectant parents, and follow-up steps are provided in case of abnormal findings.
