Non-Invasive Prenatal Paternity Testing
Non-Invasive Prenatal Paternity Testing
Weiyun non-invasive prenatal paternity testing uses advanced Next Generation Sequencing (NGS) to sequence the fragments of cell-free fetal DNA, and analyzes and compares the obtained fetal genetic information with the biological information of alleged father, so as to determine the parent-child relationship as early as 8 weeks of pregnancy.
Compared with the traditional prenatal paternity testing, Weiyun non-invasive prenatal paternity testing only needs to take 10ml of venous blood from pregnant women for detection, rather than the extraction of amniotic fluid or villi through puncture surgery, eliminating the risk of infection or miscarriage.
*CVS has a miscarriage rate of 1-2%, while amniocentesis has a miscarriage rate of 0.3-0.5%
Project Features
Strong safety -only needs 10ml of pregnant women's venous blood for inspection, eliminating the risk of infection or miscarriage caused by puncture surgery, safe and worry-free.
High accuracy -relying on the latest NGS technology, the accuracy of the test result is as high as 99.9999999%.
Strict procedures - the inspection procedures are clear and rigorous, including inspection application sheet, informed consent form, testing report, etc.
Fast detection -usually takes 5~7 working days, the fastest can be 3~4 days.
