DNA Testing: How It Works

DNA testing is like something out of a Star Trek episode. It would surprise you to learn of all the things that exist now that were once only a science fiction writer’s dream. In other words, the science used to make DNA tests possible is groundbreaking. The scientific definition is a bit difficult to understand. Basically, a DNA test is the mechanism through which an individual’s personal genetic code can be compared against some other genetic code. That may sound very technical, but it’s actually quite straightforward. You need a sample from two or more people so you can compare them.

A DNA test is generally associated with trying to figure out whether or not somebody committed a crime. If you watch crime dramas on television, you’ll hear the words “DNA test” quite often. Entire shows are built around the topic of obtaining a person’s sample in order to run the test. The test is also often used to figure out whether or not somebody may be predisposed to a particular illness. In some cases, it is also used to help people figure out whether or not an unborn child might be born with a certain sickness. That use is somewhat controversial, but it’s legal. Some people worry that parents will abort children if testing shows the child will have some sort of birth defect.

As you can see, the implications of DNA are far-reaching. In the wrong hands, a lot of damage is possible if someone has access to another’s DNA. The possibility of testing errors can also cause many problems. In spite of the potential pitfalls, the benefits often outweigh the cons.

More and more people are beginning to realize just how valuable it can be to have a DNA test done. The test can help law officers to either exonerate a suspect or find one that is guilty. The test can help a person learn if a child belongs to them, it can help people know if they’re related and much more.

DNA testing isn’t a typical test you take at your doctor’s office. Usually, you’ll either take a home test, visit a testing facility or provide a sample to law officers. If it involves an unborn child, then your doctor will be able to help you. Your doctor will either perform the test onsite or send you somewhere for the test. You have nothing to fear because providing a sample is easy, and it takes less than a minute.
