Following are questions and answers that may address your immediate enquiries on common concern on DNA testing. Please feel free to consult with us if you have any further questions.
A DNA paternity test is the most accurate form of paternity testing currently available. If the DNA patterns of the mother, child, and alleged father match on every DNA probe, then the probability of paternity is 99.999% or greater. This means that the man is "practically proven" to be the father of the child.
If the DNA patterns between the child and the alleged father do not match on two or more DNA probes, then the man is 100% excluded and has a 0% probability of being the child's father.
DNA paternity testing uses the DNA (deoxyribonucleic acid) genetic material in the cells of your body to determine parentage. At the moment of conception, the 23 chromosomes present in the woman's egg and the 23 chromosomes present in the man's sperm combine to give a total of 46 chromosomes to the child. These 46 chromosomes are presents in every cell of your body (with exception of the sperms and eggs that have 23 chromosomes). Thus, every parent has given the child 23 of their own chromosomes. Paternity testing analyses whether the parent has indeed given the child part of his/her genetic material.
No. The DNA paternity test can be performed even when the mother is not available. If the DNA probe patterns between the alleged father and child do not match, then the man is still 100% excluded from being the biological father of the child. If the patterns match, the the probability is 99,999% or greater that the man is the father. The person who brings the child in for testing must provide proper identification for the child.
Children can be tested for paternity even before they are born, so there is no age limit on when a paternity test can be done. DNA testing can be performed on a very small blood sample (about 1/4 to 1/2 a teaspoon) or a mouth swab (buccal swab), so newborns and infants can be easily tested. To test paternity before birth requires that Chorionic Villi Sampling (CVS) or Amniocentesis be performed to gather appropriate cells.
DNA testing can also be performed post-mortem by collecting specimens at the coroner's office.

Paternity testing can take place from a wide variety of cells, including blood samples, cheek cells, tissue samples, and semen. Each test provides the same accuracy, due to the presence of DNA material in every cell of the body.
To get the buccal swab (mouth swab), a buccal swab is used to gently massage the inside of the child's or adult's mouth to gather the cells. For details please click cheek cells
The DNA paternity testing results show conclusively whether the alleged father is the biological father or not. He is either included by greater 99.999%, or excluded by 100%.
