 What is a non-invasive prenatal paternity test?

A non-invasive prenatal test is a way to determine who the father is before is before the baby is born.While the mom is pregnant,the DNA profile of the baby is determined from free-floating fetal cells found in the mom’s blood sample.The baby’s profile is compared to the DNA profile of the man tested-his DNA is collected by a simple mouth swab,nails,hair with hair follicles,etc. A report is then generated to show if the man tested is or is not the biological father.
