The breakthrough inventions in the field of technology have influenced every field known to man. With the introduction of DNA paternity test, gone are the days when in order to confirm the paternity of the baby, faces of the supposed father and the baby were compared to check the resemblance in their physical features. In current times, this test is considered the most accurate way to determine the biological father of the child.

A DNA paternity test is mostly performed when the biological father of a child is not willing to accept the child as his. This test can also be done during the initial stages of pregnancy. If you are planning to go through this test before the baby is born, then you should consult an experienced physician. The physician will check the vitals of the mother and the fetus to confirm whether the test will pose a threat to the unborn baby. Seeking the advice of a professional before opting for a prenatal test for DNA paternity is essential as the chances of miscarriage are very thick.

If the physician feels that there is some risk involved, he will immediately refuse to perform the test. If this is the case, the would-be parents have to wait for the baby to be born in order to undergo the test. But, if the physician feels that there is no threat to the baby, you can go for the prenatal DNA paternity test.

To perform the DNA paternity test, the supposed father's hair, semen, blood and other physical things are required. The current standard of sample for this test includes using an oral swab to collect the saliva samples of the father. The result which you get is sure to be 99.9% accurate. Besides this test, DNA profile analysis is a process in which a DNA sample is run through a series of test to verify the identity of an individual. This method is mostly helpful in the cases of law enforcement to put criminals behind bars.

The DNA profile analysis relies on short tandem repeats (STRs) present in the DNA of every organism. This string of DNA provides valuable information about an individual as each sample is unique. The sample of the missing individual is collected from the crime spot and is compared with the DNA samples of the criminals which are present in the database of the investigation department. The DNA profile analysis can also help determine the relationship between two individuals as people who are related share some common STR's in their DNA. Thus, this technique can also be used to determine the paternal identity of the newborn.

The DNA profile analysis is performed in the laboratory by an experienced pathologist. These professionals are well trained to work with a wide variety of samples. This is a very complicated process because stress is put on the consistency and accuracy of the forensic evidence. Thus, the pathologist has to follow all the necessary guidelines in letters, in order to leave no chance for mistakes in the reports. The result obtained from the DNA profile analysis is believed to be absolutely accurate and is one of the most effective means of proving one's identity.
