Ankang paternity test center can do it.
Non-invasive DNA prenatal screening technology is to directly extract 5ml from maternal blood from 12 to 24 weeks of pregnancy, and use the free fetal DNA in maternal plasma to obtain the risk rate of fetal aneuploidy. It is used to detect 2 1 trisomy syndrome (Down syndrome), 18 trisomy syndrome (Edwards syndrome) and1trisomy syndrome (Patau syndrome).
This technology can greatly reduce the psychological burden of pregnant women, and there is no need to worry about injuries such as abortion caused by puncture stimulation. The results can be obtained two weeks after sampling, which is faster than amniocentesis and more accurate than prenatal serological screening.
