Shattered Truth

DNA Identity Testing Laboratory

Although it may seem extravagant at first glance, it is increasingly common for issues related surface in or around the adoption of a relative. Often the problem is personal, perhaps a biological relationship was never established with relative now deceased, or was uncertain. In other situations, the problem may regard legal issues such as heritage assets. Whatever questions or reasons, testing laboratories DNA are experiencing a greater number of cases of deaths.

So then the question of how to determine the relationship arise. Of course, DNA testing is the answer, but what type of sample can be collected after a person has died? In theory, any human being biological tissue containing nucleated cells may be used for DNA testing. However, many factors can affect the viability of a sample. If you decide that DNA testing is necessary and a deceased person is to be a participant in the test, if possible, a DNA sample to be secured immediately, on or around the time of death. Otherwise, it may become more difficult to obtain a viable DNA sample. Unless the cause of death is under investigation, most of the bodies will be released from a morgue in an undertaker, if chosen, relatively quickly. Upon release, an undertaker, embalming, if you chose, then will take place fairly quickly, too. The chemicals in embalming fluid contaminate tissues. This poses a problem if a DNA sample is collected from a deceased person for the purposes of DNA testing.

Recognizing the need to find a solution to this problem, Laboratory DNA Identity Testing of Bio-Synthesis, Inc. underwent an experiment. As is well known that after the embalming, the soft tissue the body will not be suitable for DNA testing, the lab had to identify a single source of DNA. The type of sample selected for the experiment was hair eyebrow. In contrast to scalp hair, eyebrows hair tends to be thicker in diameter and therefore has a more substantial root.

The nuclear DNA testing, any type of hair should have a root intact so that the nuclear DNA to be obtained. The selection of hair over the scalp hair, eyebrows hair was also due to the fact that many hair products have been found to act as PCR reaction (polymerase chain) inhibitors, which can prevent DNA amplification success (one of the steps in DNA testing).

The experiment consisted of samples of eyebrow hair (with roots) taken from 15 embalmed cadavers, ages 20 years and 75 years. The time samples were taken after embalming ranged from 8 to 24 hours. The result was that of all samples, a total DNA profile was obtained. This is notable because in many cases, non-standard forensic samples yield only partial DNA profiles. However, in this experiment, again, full profiles were obtained from each sample. Before this experiment, other experiments were carried out with other types of samples, cuttings polish, for example, with inconsistent results.

The identity of the DNA testing laboratory of Bio-Synthesis, Inc., in the past, dealt with many cases where a deceased person is required to have DNA tests and the body may have had to be exhumed. This process is not only invasive and time, can be a painful decision to make for a family member. Recognizing the need for DNA testing from the beginning, the long and complicated steps can be avoided. Family members of a deceased can rest assured knowing that not only is your loved one in peace, but also will finally have the peace of the answers to your questions relationship.
