DNA Testing in India

Gone are the days when DNA testing was considered a dream in India. With the upcoming of new laboratories, so many people are relieved. Inside every living being, even microbes, there is a unique DNA structure. DNA is becoming the most popular method for identifying individuals. DNA profiling is also called genetic fingerprinting. There are various tests available in India now. Super paternity test, sibling DNA test, maternity test, grand parentage test, DNA profiling, twin zigosity test, Y-STR testing, etc. the availability for non invasive prenatal maternity test is also available for surrogacy cases.

Some of the tests are done for peace of mind like paternity test, maternity test, non-invasive prenatal maternity test and non-invasive prenatal paternity test. If you would like to know about your family history then you should go in for Ancestry Testing services.

To find out long-term drug history the segmental analysis of hair is done.It can detect the use of drugs, tobacco or narcotics. Other tests like urinalysis, saliva test, tobacco usage tests can also be conducted.
The labs are equipped with the latest and advanced DNA testing systems to cater the needs of the customers. As the crime rate is increasing, these tests come as a blessing for the police and the public. This will help in solving many cases like sexual assault, missing person and disaster victim’s identification. The results are 100% accurate. Previously, with less laboratories, the cases remained pending for long duration. It also led in delay in justice since the crime could not be proved. With the coming of new laboratories, the tests have been fast tracked and now the results would be delivered faster. DNA can also be used for identification the accused in cases of murder or rape. In certain cases the identity of the criminal is not clear, in those cases DNA test is a sure proof of identity.

It can also be a proof of parentage or grand parentage.Every cell in our body contains a complete set of DNA, our bones, our blood, our hair, our skin and even our bones.We, humans have 23 pairs of chromosomes that we inherit from our parents. In each pair of chromosome, one is from our mother and the other from our father. A DNA paternity test compares if the man is the biological father of the child or not. A child’s DNA pattern is compared with the alleged father’s .To see if two children share one or both parents, a sibling DNA test can be conducted. DNA test can also be conducted to know if the woman is the biological mother or not. Maternity DNA Test compares the child’s DNA with that of the alleged mother.In certain cases, the father disagrees to undergo the test or maybe he is unavailable, the alleged father’s parents can undertake the test. This will determine if they are the biological grandparents of the child. This is the grand parentage DNA test. Even samples of hair or toothbrush can be used in cases where the father does not agree to undergo the test.

The DNA tests can be conducted in many ways. Two of them are restriction fragment length polymorphism (RFLP) and Polymerase chain reaction (PCR) using short tandem repeats (STRs).
