Forensic DNA Testing: What is it?

Perhaps the terms forensic DNA testing is somewhat misleading to those who are not really acquainted with how DNA paternity testing companies operate. The term forensic immediately bring to mind crime scenes and criminal investigations with groups of doctors and pathologists testing minute traces of human tissue or blood found at crime scenes in order to catch the killer.

When we talk of forensic DNA testing in companies carrying out paternity testing, we actually refer to DNA testing using forensic DNA samples. Let’s make this clearer. Typically, all DNA tests (paternity tests, maternity tests, Y chromosome tests, aunt and uncle testing) are carried out using oral mouth swabs. Extracting DNA from oral swabs is simple and moreover, DNA is easy to collect in this way. But what do you do if you are unable to get a saliva sample from a test participant? The person from whom you require DNA is dead or the person lives far away and is unavailable for the test. Well in these cases we can resort to forensic DNA testing.

Are there any other alternative sources of DNA we can use for our DNA test? Do you have any hairs that belonged to the deceased to run a hair DNA test? Or perhaps used condoms, blood stains for a blood DNA test, or nail clippings. The list is long and extensive. The DNA testing company will fully advise you and how to store and send your sample but more importantly, whether the sample you have is any good.

Different samples offer different success rates; in other words, some samples are better than others. Do not hesitate to contact the DNA testing company for more information about forensic DNA testing services.
