id=”contentNote” In the delivery room was all joy. The midwife cried when congratulated Dew and walked to the drink to give him a kiss. The father was happy and, outside, the family opened a champagne. But when the mother saw her brand new daughter came down the world. It was perfect. It was very pretty … but had the face of your ex.
Stories like these are increasingly common: couples who go through nine months without knowing who the father and to determine resort to a DNA , whether during pregnancy or immediately after birth.
Consultations of this type grew exponentially in the last five years, they said center managers in genetic studies are conducted.
In Argentina Society for Forensic Genetics there are 18 laboratories authorized for this type of testing, ten of which perform prenatal testing.
“A decade ago we were five prenatal testing each year. Today, more than 200. And we have three queries per day. They represent 10% of all studies of DNA,” explains Eduardo Raimondi, by the Pricai, the center of genetic studies Favaloro Foundation.
Paternity studies are not a rarity. “Today, statistics indicate that ten children born to one or two that are not biological children of their legal parents ” Viviana says Bernath, a member of the Argentina Society of Forensic Genetics, Director of Genda Lab, for each month that usually takes four to five pregnant.
The risks for the baby
“We also recently increased the amount of paternity studies performed to infants during the first year of life. They are women who for some reason, perhaps because of the risk involved in the study during pregnancy, prefer to wait until the birth to do it, “says Dr. Bernath, who published the book last November DNA, lie detector.
There are two types of studies are used to perform prenatal paternity testing. The first is the chorionic villus sampling, which involves a needle between weeks 12 and 13 of pregnancy. The other study was done by taking a sample of amniotic fluid from 16 weeks. For all cases, this requires that the mother and alleged father.
Depending on the laboratory, the results can be obtained within a week, the fast version, or a month.
“Mothers should know that prenatal testing involves a risk to the baby, which is at least 0.5%, but there is,” explains Primarosa Chieri, Primagen laboratory director, the first in the country engaged in such studies. It means that one in 200 pregnancies undergoing this test is lost.
The study of paternity after the birth is via a buccal swab samples and must be made to the mother, father and baby.
There are kits to take home samples, but the labs are not recommended, because in that case, the study loses validity of legal proof. This study will cost between 250 and 300 dollars, depending on the speed.
“Do not fall into the trap of pointing among the causes of this growth to increased promiscuity consultations. This is historic, the difference is that now more accessible as possible to know for certain paternity,” says Chieri.
The profile that most characterizes this type of query is Primagen of women who went through a change of partner and became pregnant in that course. In other laboratories also indicate that there are frequent consultations of men who had sex with a woman who knew and with that came a couple of times, but who want to be sure to be the parents of that baby on the way.
Also classic is the women attending consultation with her lover. At the news of pregnancy, they want to be sure that a child of her husband before making the announcement.
“In the laboratory hall you can see everything. From couples who are happy and relieved to see the test results to those that are dislodged, cry or scream. There is no lie that resist DNA testing,” Bernath concludes.
