A number of forensic experts from the Netherlands succeeded in developing techniques to accurately calculate the age of a person through blood. They learn through the distinctive character of immune cells in the blood, known as T cells
As quoted from the pages of the BBC, this finding is useful to reveal the identity of perpetrators or victims of crime. Through a blood test that scattered at the scene, officers can easily predict the age of the perpetrator or victim who has not revealed his identity.
T cells that are used to predict that age plays an important role in detecting foreign bodies in the blood such as bacteria, viruses, parasites, and even tumor cells. While working to identify a foreign body, a small molecule of DNA will be formed. This molecule has a linear and stable relationship with a person's age.
Study author, Dr. Manfred Kayser of the Erasmus MC University Medical Center, Rotterdam, said the test results of these T cells have a fairly high degree of accuracy. In fact, a number of expert design center for reading human character based on DNA information.
"So far, DNA testing of conventional forensic teams carried out only able to identify someone based on a comparison of blood relatives. But these findings are expected to display information to help discover the identity of an unknown person at all," said Kayser.
