Inspection Project Profile
DNA paternity testing is a method of DNA detection, using biological and genetic theory and techniques to compare the DNA type of parents with the DNA type of the fetus, and analyze the genetic characteristics to determine whether there is a parent-child relationship between the offspring and the parent.
When a mother is pregnant, a small amount of fetal DNA enters the mother's blood through the placenta. Fetal DNA can be isolated from the peripheral venous blood of the mother, making prenatal paternity testing possible.
Relative to different types of paternity testing, DNA prenatal paternity testing is the only one that can determine parent-child relationship at the earliest stage of pregnancy.
Invasive fetal paternity testing methods such as conventional amniocentesis and chorionic villus sampling require pregnancy for 10 weeks to detect, and improper operation may endanger the fetus and maternal health, such as intrauterine infection or abortion.
DNA prenatal paternity testing (extracting maternal peripheral blood) is the only non-invasive, non-invasive prenatal paternity test. Non-invasive, painless, safe and risk-free, generally blood sampling can be performed in pregnant women 7 weeks of pregnancy. DNA prenatal paternity testing to eliminate parent-child relationship accuracy of 100%, without excluding the parent-child relationship accuracy of 99.99% or more.
