Basics of a prenatal cell-free DNA (cfDNA) screening?

The prenatal cell-free DNA screening is a blood test for a pregnant woman. During the period of a pregnancy, some DNA of the unborn baby circulates in the mother’s bloodstream. This screening is also known as the “noninvasive prenatal screening” because there is no use of surgical instruments. This test is also considered very safe. The cDNA screening is used to check this DNA to find out if the baby is more likely to have any kind of disorder such as Down syndrome or another disorder caused by the trisomy.



During the procedure

In this screening, a maternal blood sample is taken and then sent to the lab. The lab will analyze the maternal and fetal DNA in the blood sample. A higher than expected ratio of chromosome 21 indicates the increased risk of the disorder such as Trisomy 21 in the fetus, this disorder is the main cause of the Down syndrome.

This test is recommended for women who are at least 10 weeks pregnant. Contact Noninvasive prenatalDNA testing Texas professionals who can help you in getting the cell-free DNA screening.



Before you choose any particular DNA testing center, you should do research in advance to know the facilities, accreditations, and track record of your selected DNA center. You can also ask the Noninvasive prenatal DNA testing cost before the starting of the DNA testing procedure so that you don’t get any issue in the future.

DNA Facial Recognition

DNA Facial recognition is an identification or verification of unidentified biological material against facial images with a known identity.   It is an advanced technique that is scientifically created and based on your skin's genetic make-up. It is mostly used for security purposes just like we use biometric security in phones and offices. How Facial recognition works? EDFPC (Electronic DNA Facial Point Connectivity) is a biometric process that scans human face manually with using a unique pattern. It scans the human face and then compares related facial traits to another person’s facial traits. It also uses a patented 16 Point Facial Connectivity system to assist in determining the genetic relationship of an alleged family member. EDFPC introduced the algorithms used to perform various DNA tests for facial comparisons. Benefits of Facial recognition •        Facial recognition helps people to know more about their family background. •        DNA fingerpri
