As India is a densely populated country, human identification is the last thing that comes to mind when we think about development.  DNA screening center came as a surprise to most Indians. Now human identification is possible just by submitting a sample. Making the most of it, the criminals knew that there was no one to help the injured. There have been many cases of child exchanges and Child swapping everywhere. Children were exchanged in hospitals by staff or other people simply for money. The parents of the newborn came to know by sources but were powerless because there was no evidence. In a recent case, parents asked for a DNA test from the child that they were handed over by the hospital and also from the family that was there in the next room. The other family refused to get the DNA test of their newborn. The mother, the injured, was sure that she had given birth to a little boy who had been exchanged afterwards. The nurse had informed her of the ...

DNA, deoxyribonucleic acid is a complex chemical structure that is unique and different for each organism.  Every cell in our body contains a complete set of DNA. It can be located in our hair, our blood, our skin and our bones. DNA is the basic building block. While a complete set of DNA is called a genome.  Two popular methods for DNA testing are restriction fragment length polymorphism (RFLP) and polymerase chain reaction (PCR) using short tandem repeats (STR). All living beings have a different number of chromosomes. We humans have twenty-three pairs, which are inherited from our parents. In each pair of chromosomes, one is from our father and the other from our mother. A DNA test is required to establish the relationship between the DNA profile of two or more individuals.  It allows a biological relationship between these two people. The test may be to prove identity, paternity, grand parenting, immigration purpose or in cases of crime where it is difficult to ...

The paternity test determines whether a particular man is the biological father of a child or not.  When the baby is conceived, it receives half the genes of the father and half of the mother.  This test can also be performed before the birth of the child. This test, when performed before the birth of the child, is called a prenatal paternity test. However, this paternity test can be done after the birth of the child. Confidential paternity testing proved to be a blessing as there was a clear picture of the child's filiations. There are many cases of child exchange in India. Parents are always worried and have this issue in mind. A simple DNA paternity test is the answer to so many questions.  This develops a strong bond between the father and the child. This test is mainly performed with the buccal cells inside the check.  The test is painless and the sample can be collected at home.  The kit may be tested after collection of the sample. Ho...

The Paternity DNA test specifies whether a given person is the biological father of a child or not. Since this test is made for peace of mind, it is the freedom to perform this test at home too. There is a naive method by which the person can collect his own samples using self-dressing kits. This test is performed by collecting buccal cells found inside the cheek of a person.  The swab has a cotton end and a wooden or plastic handle. He can then submit the sample to the laboratory. There are different tests available. The standard test - this test is done by parents for peace of mind.  The motherless test - this test is done if the mother does not agree to get the tests done.   Legal Paternity Test - These tests are conducted for property disputes, custody cases and for immigration. As people become sensitive, the demand for DNA paternity testing is growing. It helps in legal cases. It forms the social security for the child and the mother. It is also usef...

The DNA tests broke all the borders and united the family members who had left because they had no proof of relationship.  It is government policy that the sponsoring family must prove that there is a biological relationship between the petitioner (sponsor)  and the beneficiary (sponsored person). USCIS, Citizenship and Immigration Services of the United States ordinarily order the presentation of DNA test results to verify that there is a biological link between the two. Many countries want DNA  testing as proof of relationship. There are a few things you need to keep in mind before you do the test. The laboratory you are approaching must be reliable.  It should also be reasonable and must also provide results in a timely manner. There should be a free advice for customers and easy  collection of samples of the door should be available. DNA is the only non-documentary method accepted as evidence of a biological relationship. Previously people used...
