Answer
Hello,
From the 7th week of pregnancy, the fetus begins to release free DNA into the mother's blood, NIPT technique is used to separate these free DNA to analysis. This method only requires 10 mL of pregnant woman's blood to do the test, so it is safer for both mother and fetus compared to the traditional method of amniocentesis.
Advantages of non-invasive prenatal DNA testing service:
Safe for both mother and child Performed from the 7th week of pregnancy 99.9% accurate The child's (fetal) DNA sample is a blood sample from mother (pregnant woman). The father's sample can be oral mucosa, blood, dried blood, hairline, fingernails (foot). You can go to the hospitals of Vinmec Health System to get more detailed advice from specialist doctors.
