How Does DNA Testing Work For Paternity: Myth And Reality
How Does DNA Testing Work For Paternity: Myth And Reality Staff

Paternity can be confirmed using very accurate tests on the father (or supposed father), mother, and child's blood or tissue samples. The accurateness of these DNA tests ranges from 99 to

99.9 percent. They can rule out a man who isn't the biological father, and if he isn't, they can indicate the possibility of paternity. When it comes to ensuring child custody and maintenance, these exams have a substantial legal influence. Let’s get ahead of the myths and debunk them once and for all and know-how does DNA Testing works for Paternity.


The market is inundated with alternatives for people wishing to take a DNA paternity test. A DNA test can be done at a clinic, a hospital, or even at home with at-home kits. The accuracy of the findings won't differ significantly across testing facilities and at-home kits because the tests all employ the same laboratory methodologies. As long as the test is completed at a facility recognized by the American Association of Blood Banks (AABB), the results won't differ greatly.

The method of testing you select will be determined by the intended use of the results. At-home testing kits can be used to do DNA tests for peace of mind, in which saliva or cheek swabs are collected, packed, and shipped to a testing location for examination.

Paternity testing can be conducted at any time throughout pregnancy. In this situation, the test will be performed in a hospital, and DNA tests for genetic tests will be acquired in one of two methods during pregnancy. 

Types of Paternity DNA Testing

The first one is chorionic villi screening, which can take place anywhere between 10 and 12 weeks after conception. As per the Cleveland Clinic, this procedure entails putting a probe into the uterus via the vaginal or abdominal wall to harvest a tiny portion of the placenta. This will hold a huge amount of the fetus' DNA, which can be examined simply and fast.

Collecting a specimen of the mother's blood, which contains minuscule levels of cell-free fetal DNA, is a considerably less intrusive method. In some ways, they can function as a "genetic signature," because everyone has identical STR segments, however, the mix of STR length a person inherits is unique. More crucially, because the father contributes 50% of a child's DNA, around 50% of such STRs should be carried between them.

Following that, these segments are measured using a technique known as Polymerase Chain Reaction, PCR. This is a technique used by geneticists to "amplify" certain areas of DNA. Many STR regions are duplicated again and over again in paternity testing.

Myths and Realities of DNA Paternity Test

Paternity testing is costly

The cost is determined by who conducts the work as well as if the results are to be utilized for personal knowledge alone or legal purposes. Quality must never be compromised for cost, especially in delicate instances like paternity testing.

Paternity testing is a long process, not instant

It may be more expensive if you require the findings immediately. In most circumstances, a few laboratories provide findings in five days or less.

Paternity testing splits families apart

Testing assists the kid in circumstances where paternity must be established for inheritance or policy purposes, as well as in child-support and custody proceedings. 

I'll have to delay until the kid is born before I can get a paternity test

A paternity test can indeed be requested throughout a child's pregnancy; however, this procedure is more expensive because obtaining samples and analyzing them is more complicated. A paternity test can also be ordered as soon as 9 weeks of gestation. Blood samples both from the mother and father will be necessary. Paternity can be determined as early as 11 weeks after the baby's conception.

Paternity testing is difficult and painful

That is not correct! Buccal (cheek) swabs are used to collect test samples. Participants swish the inside of the cheeks for 30 seconds (a parent may be required to take samples for the kid if they are young), and that's all there is to it! Even newborn newborns' cheeks can be swabbed.

Paternity testing based on DNA is not very accurate

Positive test findings are often more likely than 99.99 percent of the time. Every paternity test is run twice to ensure that you have complete confidence in the results.
