Do you need a DNA test to see who’s the father of your child?There had been other biological identification tests like Blood typing, HLA test, and serological testing in the past to identify the alleged person as a father of the child. These tests still have good chances of confirming paternity, but they can be less accurate, time taking, and less conclusive than the DNA test.

DNA tests have been of the prime importance of confirming the child’s father when the paternity is in doubt. Parental DNA test has helped resolved issues regarding the rights and custody of children in sensitive cases, especially divorce. Parental DNA testing can confirm paternity for both children and adults.

How Does Parental DNA Testing Work?

Collection of DNA Sample

For a paternity test first, you need to collect the buccal sample of the person. You will need to rub the inside of the cheek with a cotton swab to get as many buccal cells. After that, you will send it to the lab for testing. You will also need to send the sample of the alleged father to match with the child or person.

DNA Profile

Parental DNA test uses the DNA profiles of individuals to check the paternity. Your DNA is the combination of both your mother and father’s DNA. You have to make a comparison between DNA profiles of the person and alleged father to identify the alleged person’s fatherhood.

In case of testing paternity of a male, the matching of the Y chromosome is also useful as the Y chromosome transfers directly from father to son.

Test Results

The analysis and comparison of DNA profiles take place in a way to find out the probability percentage. If the probability is 0%, the test denies the paternity of the alleged person. If the probability is 99.9% or greater, the parental DNA test confirms the paternity.

Techniques for DNA Test

The techniques currently in use for parental DNA testing are RFLP( Restriction Fragment Length Polymorphism) and PCR (Polymerase Chain Reaction). RFLP involves cutting of DNA with a special type of enzymes, namely restriction enzymes. The fragments of DNA separate according to their length on an agarose gel. Patterns of DNA fragments differs for every individual.

The use of PCR is prevalent for parental DNA test. In simple words, PCR generates millions of copies of DNA from a minute amount of sample. The primers with fluorescent tags attach to the extracted and denatured DNA before the amplification( production of million copies). The fluorescent tags make the DNA markers luminescent on the agarose gel.

DNA Test for Unborn Child

A paternity DNA test for the unborn child is also possible. The DNA test for the unborn child can be either invasive or non-invasive. Invasive parental DNA test involves the collection and examination of the chorionic villus sample from a pregnant woman. The test yields highly accurate results as the sample come directly from the fetus.

The noninvasive test is simple as it requires only the collection and examination of the blood of a pregnant woman. There is a little amount of fetal DNA present in the mother’s blood after seven weeks of the baby’s growth. However, the test results are slightly less accurate than the invasive gestation test.
