DNA-Identity check

At Corion, we send our patient's samples for DNA-ID Check to DNA Diagnostics Centre (DDC), USA where this highly specialised testing is performed at a very affordable fee. You can rely on your paternity test results from DNA Diagnostics Centre because of the highly efficient laboratory they have. DDC is an International Organization for Standardization (ISO) certified laboratory as per ISO/IEC 17025 standards. The American Association of Blood Banks (AABB), an organisation that demands the highest standards in DNA testing, also accredits it.

DNA (deoxyribonucleic acid) is the genetic blueprint that determines a person's biological characteristics. It is located in every nucleated cell of the human body. Upon conception, a child inherits one half of his DNA from his mother and one half from his father. The unique combination of DNA, once analysed, will match that of the biological parents. When a paternity test shows that a child's DNA DOES NOT match that of the alleged father, he is excluded as the biological father of the child. When the child's DNA DOES MATCH that of the alleged father, we can prove a probability of 99% or greater for paternity.

To arrive at a probability of paternity, human cells are first extracted from the tested parties. Cheek cells are collected from the mouth with a buccal swab. In the laboratory, these cells are removed from the swab. The DNA from these cells is then extracted, and cut into sample fragments with enzymes. These fragments are placed into a gel matrix, where an electric current drives the fragments across the gel. Later in the process, these fragments are exposed to a labeled DNA probe. This probe recognizes and binds to a unique segment of the person's DNA. Where this probe binds to each person's DNA is the key to establishing relationships. A film is developed which will reveal black bands wherever the probe has bound to the individual's DNA.

The pattern of a child is unique - half matches the mother and half matches the father. If it is revealed that the band patterns of the alleged tested father / mother DO NOT match that of the child, that person can be conclusively excluded as the child's father / mother. If the patterns DO match, the probability of paternity begins to grow. DNA testing is very scientific, and very accurate.

We at Corion are able to provide sterile kits for the couples to get the test done or alternatively you can get your child to our clinic & our trained laboratory personnel will help you collect the swabs. The swabs will then be couriered by us to DDC & you can expect the report in a week to 10 days time. For any further details of DNA-ID Check, you can write to Corion IVF Laboratory at
