DNA testing is one of those terms that most of us learned about from television serials and movies. Remember those crime shows where the cops trace the most cunning antagonists in super hi-tech labs that are built at the most coveted locations. The dedicated teams of genealogists and scientists use limited evidences from body parts such as a broken nail or a hair strand to decipher the most difficult crime mysteries in the most intriguing manner and that too within a couple of hours. Other than that there have been family dramas revolving around complex relationships that trigger emotional roller coasters among family members. Just when the relationships get begin to get extremely turbulent, a magical ‘medical’ report, called the DNA report, issued by some science genius cracks the whole paternal or maternal lineage and fills in the family tree and suddenly everyone’s mind find their peace.

DNA, or Deoxyribonucleic Acid, is one of the most intriguing scientific discoveries made in the field of human genetics. In very simple lay man terms, DNA is a hereditary chain of code that is found in cells in human body. This code dictates a lot of key life elements about a human being including the physical and chemical characteristics of his body such as height, color of hair, eyes, blood relationships, growth and even risk level for some diseases. A DNA is in fact a unique identity that is distinctive for every human being on the planet. No two humans can have an exact same DNA. That said, the code is genetically passed on from parents to their children and may be shared among siblings, which helps establishing relationships between people from the same lineage.

Although the history of DNA’s discovery dates back to the early nineteenth century when an isolated discovery of nucleic acid was made, however, its importance as a genetical code of life was not proven until the 1950s. Later the aid of advanced technology and sophisticated statistical and scientific software and tools helped in the development of the discipline of genetical engineering that came as a major scientific breakthrough. Ever since then, DNA has been one of the favorite subject for filmmakers, playwrights and novelists for the fascinating and deep impacts that it has on human life. Unfortunately, while they became a source of awareness at one hand, somewhere these fictitious plots resulted in creating myths about DNA among masses. Here are top 3 common myths about it that are not true.

  1. A DNA Test Can Reveal Your Complete Family Tree

One of the most common myths about DNA that most people believe, thanks to the movies, is that a test can reveal their complete family tree. This is not true. It is a scientifically proven fact that DNA is a complex code that is passed over generations across genetical lineage and have the capability to connect genetically related subjects. That being said, the scope is limited to the fact that while it can prove that Person A and Person B are related in some way or they belong to the same ancestral lineage, it cannot prove exactly how the two people are related and what is the exact relationship between them. This means that while you can figure out if you are related to a person or not, you cannot establish how you are related to him and where the particular relative stands on your family tree does.

Moreover, it must be noted that the results can only connect your DNA code with the results that are already in the database. This means that your DNA can only be matched with people who have actually taken a test and their results are available for comparison. Not everyone takes a test which means that a prospective relative cannot be revealed because the record of his DNA is not available in the database since he might not have taken a test.

  1. You Can Get DNA Results Within Minutes

Those magical science labs in your favorite crime shows lied to you about the speed of test results. DNA is a complicated test with an in-depth procedure and it is not possible to give the results in few minutes or even in couple of hours. That said, thanks to the advancements in computer software, they do not take ages and you can get the result in a couple of days.

  1. DNA Tests Are Expensive and Not Everyone Can Take A Test

Another very common myth about is that these are super expensive tests and only people at positions of power, such as law enforcement authorities can decide if someone should or should not take a  test. It is true that in the initial years, when the tests were not that common, DNA was an incredibly expensive test. However, over a period of time with DNA testing laboratory services such as Lextox readily available for public, anyone can take a test and they are not very pricey. That labs may charge additional payments if the tests are being taken in special contexts such as legal or medical purposes.
