Different Ways to Collect DNA Samples

 

DNA is a fascinating topic that might seem like it doesn’t get enough credit all of the time. When you consider that DNA testing was actually put to real use in 1985, genetic research appears to be relatively young. There is still a lot to learn about DNA, but you can still take advantage of genetic research in the meantime. In fact, genetic testing is a great way to learn about your parentage, sibling relationships, health conditions, and even general ancestry. In order to do this, you will need to collect DNA samples and submit them for analysis and comparison. There are a few different ways to collect DNA samples, including cheek cells, blood, hair, and fluids – see more at Gtldna.com.

 

Cheek Cells

 

Collecting a genetic sample from the cheek is a simple process that most people can do at home. It helps to have not eaten for a few hours before swabbing, and to drink some water in order to clean your mouth of food particles. You then just take a sterile cotton swab and scrape it on the inside of your cheek. Once completed, you need to seal it in an approved, sterile container.

 

Blood

 

Collecting a blood sample is a little trickier than a cheek swab, and is not usually recommended to be done at home. For blood samples, you may need to visit a licensed phlebotomist at an approved laboratory. The technician will clean the area where the needle will be inserted and put a tourniquet on your arm. They will then insert a needle into your arm and vein and draw some blood. When finished, the tourniquet will come off, the needle pulled out, and you will get a bandage. The sample will then be sent off for analysis.

 

Hair

 

Another easy way to collect a sample for genetic testing is to just grab some hair. The hair can come from a hairbrush, but you want to make sure that it is definitely a hair from the person that you are looking to have tested. Some types of genetic testing may allow you to submit a hair sample for genetic analysis, which makes it simple for you to collect the sample and send it in on your own.

 

Fluids

 

DNA can be gleaned from the fluids that a person makes as well. If your testing allows for it, you may be able to submit samples such as a person’s sweat or saliva. Again, these samples are simple enough to collect that you may be able to do so from home without going into a laboratory.

 

DNA testing has come a long way over the years, especially since the mid-1980s. Although it is likely to continue to develop by leaps and bounds, you can take advantage of what science has learned about genetic testing today. All you need to do is collect a DNA sample for your desired test. The methods listed above are the most common ways to collect samples for analysis. The method of collection may be determined by the type of testing you are looking to have done and the sample amount that is needed. Remember to leave collection of samples like blood to licensed professionals.
