The inventions and discoveries of latest technologies in the field of science has taken the world by storm. Among the various inventions, DNA relationship testing is worth mentioning. This procedure is mostly performed to verify the biological relationships among family members. In order to perform this test, DNA sample of the suspected individual is required. The sample is usually collected by scrubbing the inner side of the cheek with the help of the buccal swabs. Among other methods available, the result obtained from this test is considered to be the most accurate.

It is a known fact that DNA particles within human body are declared as genetic blueprint that distinctly identifies an individual. Thus, in order to carry out the DNA relationship testing, these particles play a vital role. This test can also be done to confirm the paternity of a child when the mother of the child is unsure. This is because the child inherits DNA from both parents. Thus, this DNA relationship testing procedure involves carrying out series of tests to confirm the paternity of the child. This test can also be preformed before the baby is born provided there is no risk to the baby.

This DNA relationship testing procedure is performed by a physician. Before the test is done, the prescribed doctor will check the vitals of the mother and foetus. If the doctor feels that there is no risk involved then he will be willing to conduct the test. But, if he feels that there is even a slight risk to the foetus, he will refuse to do the test. In such cases, the parents will have to perform the test after the baby is born.

The DNA relationship testing procedure is also very helpful in legal cases as well as other personal issues. During such cases, the test is mostly conducted under legal supervision. Along with these tests, the DNA profile analysis is performed mostly to verify the identity of an individual. This test is very useful in the law enforcement area to identify the criminals for their wrong doings. As the name suggests, DNA sample is required to conduct this test. This test can also be conducted to verify the biological relationships among individuals.

There are several institutions around the globe that conducts the DNA profile analysis test. This test is mostly carried out in laboratories by a professional in this field. In this test, the DNA sample is run through a series of test to identify the source of the sample or to be used as a base of comparison between two samples. Thus, the DNA profile analysis helps to identify the DNA of someone who is unknown or the DNA of someone who is known and it can be used in various fields. This technique relies on the presence of STR (short tandem repeats) which is present in the DNA of every human being.

The DNA profile analysis is conducted with the help of STR because no two individuals have the similar such particles. Since the procedures involved to complete this test is very complicated, it is conducted by an experienced pathologist. Thus, DNA profile analysis is one of the most effective means to confirm ones identity.
