Non-Invasive Prenatal Paternity DNA Test with maternal blood [Before birth]

With the competency and experience of DNA Laboratory, we can offer you exclusively for an accurate prenatal paternity DNA test service with no risk to the mother and unborn baby. Moreover we can also perform the non-invasive prenatal paternity DNA testing as early as the 7th gestational week. Determine the paternity of the unborn baby can cut short the months that you have to wait.

We offer a highly accurate, non-invasive prenatal paternity DNA testing service for your peace of mind. These scientific breakthroughs in the field of prenatal genetic testing and paternity DNA tests using pregnant woman’s blood have become available. Starting at early gestation week of pregnancy, we are able to detect a trace amount of fetus DNA in pregnant woman’s blood and compare with the DNA of the alleged father. (From Website)

Our testing method captures and analyzes many specific DNA markers from alleged father, mother and fetus from the specimen. Those extracted and available DNA will undergo DNA amplification and ultra-high resolution separation. Finally DNA analysis will be processed to provide accurate results to prove parentage with up to 99.99% or more inclusion rate and 100% exclusion rate. However, please be reminded that this test report is NOT intended for any legal purpose.

Look no further! We have a long history of providing a complete solution for human identification and DNA relationship testing to meet the needs for both profession bodies and the general public.

At least 3ml of blood will be drawn from the individual.
