5 Most Common Reasons Why People Opt For DNA Testing

DNA testing has been used since 1986 when it was utilized during a criminal investigation. Now, doctors use it to determine if a person has a certain disease, to diagnose people with illnesses that require a DNA test or to find out your lineage. Furthermore, DNA testing is more common than you might think. Read on to learn about the most common reasons why you should have a DNA test.

What is a DNA test?


The common DNA test is when a doctor takes a buccal (cheek) swab from their DNA kit and quickly swipes some saliva from the inside of your mouth. However, there are other ways of DNA testing aside from a simple cotton swab.

Other than saliva, doctors can test DNA from these samples:

  • Hair
  • Blood
  • Skin
  • Amniotic fluid (Fluid from the fetus during pregnancy)

Doctors can get DNA samples from almost anywhere in your body. But you may be asking yourself “why would I need DNA testing?”

1. You Could Carry a Disease


In today’s world, inheriting a genetic disease of any kind is now considered high-risk. For example, a man is 10 times more likely of contracting prostate cancer or a woman has a 60 percent chance of developing breast cancer if they carry the genes for it. The only way people inherit these genes is through their parents. However, there are times that these genes will stay dormant within the host meaning that they won’t be affected at all, but it’s worth pointing out that it can skip a generation.

2. Problems Beneath The Surface


Congenital diseases aren’t always evident. Conditions that are metabolic or autoimmune won’t make themselves known until you’ve reached a certain age or an event that would trigger it. That being said, it’s very dangerous if you’re not aware that there may be an issue because you won’t be able to prepare to treat it in advanced.

3. Keeping Your Kids Healthy

Since you’re now armed with the knowledge, you can now take precautions in keeping your children healthy. It’s important to know that genetics aren’t the last answer. What you have to do is ask yourself “what’s in my DNA?”. For all you know, your family can have the gene for Huntington’s disease. By taking a DNA test, you’ll be able to start treatment and soften the impact it will have.

4. DNA Tests Are Simple

Getting a DNA test is extremely convenient and just simple overall. Furthermore, they are completely painless. Getting a buccal swab just feels like a toothbrush without the bristles. They are quick, easy and just as accurate as getting a blood test.

If you want or need to get a DNA test, all it takes is a quick phone call to your doctor’s office. Every single doctor’s office and hospital have DNA testing, making them available at all times.

5. Paternity Issues


Another most common reason why people usually opt for a DNA test is when they are not too sure about the paternity of a child. This test can prove, that too very effectively, who the real father/mother of a child under question.
