Verifi® by Retrogen: Non-Invasive Prenatal Testing
The Verifi® Prenatal Test represents a major advance in prenatal testing, providing accurate answers about fetal chromosomal health without the risk associated with invasive procedures, such as amniocentesis or chorionic villus sampling (CVS).
The Verifi® Prenatal Test is a non-invasive prenatal screening that checks for multiple fetal chromosomal aneuploidies using a single maternal blood draw with high sensitivity and specificity. Verifi® by Retrogen accurately detects aneuploidies such as trisomy 21 (associated with Down syndrome), trisomy 18 (Edwards syndrome), and trisomy 13 (Patau syndrome).
Verifi® prenatal testing is:
- Safe – Routine, non-invasive blood draw. Just one tube (7-10 mL).
- Accurate – Directly analyzes cell-free fetal and maternal DNA with our proprietary SAFeRTM algorithm, which has a very low failure rate (0.1%).
- Easy – Test as early as 10 weeks gestational age (8 weeks of fetal age as determined by date of conception). No limitations regarding ethnicity, BMI, assisted reproductive technology (ART), or egg donor cases.
- Fast – Results reported to partner laboratory in 3-5 business days after sample receipt (time to report may vary based on partner laboratory providing the test).
In comparison to other screening options, non-invasive prenatal testing provides more reliable results with a higher positive predictive value than traditional serum screens. Additionally, it does not carry the risk of complications that invasive procedures can have.
