Reasons For DNA Testing

DNA testing is becoming more and more popular as a way of catching criminals and establishing family relationships. But why is that DNA testing is particularly favored by blood tests and other methods of detecting parentage and what are the most significant reasons for its current use in both medical and legal circles?

1. DNA is unique to the individual concerned

Good to know that we are all unique. Our DNA is completely different from any other person anywhere in the world. It's like our own individual serial number - while we may share certain digits with others, which are essentially unique in the makeup of our DNA. What this means is that DNA testing is an important tool to identify genetic relationships, because when we share a number of DNA matches with someone who is accused of being a relative, who is usually very safe to assume that there is a genetic link . Moreover, this also helps to support DNA testing for legal purposes, where it is possible to use DNA as a strong measure to support alleged guilt in serious crimes such as murder and sexual assault.

2. DNA testing is easy to prove

DNA samples can be obtained very easily, making it ideal for testing young children. A buccal swab of saliva or hair of the head may be sufficient to provide the DNA necessary for a paternity test in order to establish a biological relationship between the alleged father and child. Instead of having to test blood types or other forms of identification of family relationships, the DNA samples are quick and easy to take of any age and pose no threat to the donor of the sample.

3. With great detail to facilitate comparison

Due to the complex nature of DNA, it is possible to use genetic data match as a highly compelling set of genetic inheritance. Add to this the fact that there is new alleles may be introduced that are not present in the parent or alleged, and it becomes immediately clear whether there is a paternal relationship in place.

4. Allows DNA testing of more distant relatives to determine paternity

DNA testing, frequently used in cases of paternity disputes, can be carried out without the need for a DNA sample from the father. What this means is that, in fact, the father is not necessary to provide a DNA sample which is not available or unwilling to cooperate. Taking the DNA of close family members related to the alleged father may be possible through DNA testing to determine if a relationship does exist.

5. DNA testing is cost effective and relatively fast

DNA testing is becoming more accessible to people worldwide. As competition increases and technology improves, the price of DNA tests have fallen drastically in recent years. This is compounded by the fact that it is fast and relatively stress-free to collect DNA samples and send to the laboratory and the results can be obtained relatively quickly, in just 48 hours.

As we have seen a number of advantages of DNA testing and paternity test which resulted in an increase in demand for this type of testing worldwide.
