Trisomy Screening Tailored for Twin Pregnancies
Specialized Prenatal Screening Designed for Twins
DNA GTx’s NIPT Twin analyzes cell-free fetal DNA (cfDNA) from maternal blood to screen for the most common autosomal aneuploidies, Trisomy 21 (Down syndrome), Trisomy 18 (Edwards syndrome), and Trisomy 13 (Patau syndrome), specifically optimized for twin pregnancies. This test provides accurate, minimally invasive screening without reporting fetal sex, addressing the unique challenges of multiple gestations.
Who is this Test for?
- Expectant mothers carrying twins
- Those who want early and accurate screening for serious chromosomal conditions
- Parents seeking minimally-invasive testing instead of procedures like amniocentesis
What it Screens for
- Autosomal Aneuploidies:
Trisomy 21 (Down syndrome)
- Down syndrome occurs when there's an extra copy of chromosome 21, leading to characteristic physical features and varying degrees of developmental delay.
Trisomy 18 (Edwards syndrome)
- Edwards syndrome occurs when there is an extra chromosome 18, leading to serious health challenges and growth delays.
Trisomy 13 (Patau syndrome)
- Patau syndrome occurs when there is an extra chromosome 13, resulting in serious health challenges affecting growth, development, and organ function.
- Fetal sex is not included in this test
Key Benefits
- Twin-Optimized Accuracy: Validated for twin pregnancies, ensuring reliable results
- Minimally Invasive & Safe: Requires only a maternal blood sample—no risk to the mother or either fetus
- Early Detection: Screening available from 10 weeks of pregnancy
- Focused Results: Targets the most clinically significant chromosomal abnormalities
- Supports Confident Prenatal Care: Enables early risk assessment and planning without invasive procedures
Turn Around Time
- 2 weeks
How it Works
Step 1: Maternal Blood Sample Collection
- A blood sample is taken from the expectant mother.
- This sample contains cfDNA from both mother and baby.
Step 2: cfDNA Extraction
- The cfDNA is carefully separated from the rest of the blood.
- These tiny DNA fragments can reveal genetic changes or risks.
Step 3: Library Preparation
- The cfDNA is prepared so it can be read by our sequencing machines.
- We add special tags and focus on the most important parts of your cfDNA.
Step 4: Whole Genome Sequencing
- Advanced sequencing reads the entire genome at high resolution.
- Provides a comprehensive view of genetic information from cfDNA.
Step 5: Data Analysis
- Our proprietary software (D-KRYPT) helps us understand what the DNA changes mean.
- The results are derived from trusted medical databases.
Step 6: Personalized Patient Report
- You got a clear, easy-to-read report with the most important findings.
- Your doctor uses the report to guide clinical decisions and care during pregnancy.
