Can you take a DNA test while pregnant?

Street Drug Test

Yes, it is possible to test the fetal cells found in the mothers blood as early as 7 weeks pregnant. This procedure is non-invasive for mother and child, so you can have peace of mind before your baby is born.

The process is fast and simple. While a mother is pregnant, fetal DNA is mixed in with her own blood through the placenta. This allows us to take a quick blood sample from the woman, and isolate the fetal DNA out. A cheek swab from the possible father is then used to compare to the fetal DNA. If a cheek swab is not available, hair samples or fingernail clippings can also be used. Any personal items that contain DNA are usable. The results are available within 7 business days.

A combined paternity index is used to determine if the potential father is a match. Currently, a CPI of 100 (probability of paternity 99%) is the minimum required to establish parentage for legal purposes in most states. The paternity index calculations look for a common gene frequency in mother child and father.
