Which Type of DNA Test Should I Use?

There are so many different ways to get your DNA tested, that I thought I would write this short article to explain them. The three most popular are direct testing via blood, saliva or hair samples, and DNA testing from a swab or sample taken from the inside of a cheek. Here is a brief description of each, in order to help you make an informed choice when choosing which method to use for your DNA testing.

DNA Testing Using Blood, Saliva Or Hair Samples – This is probably the most popular way to get your DNA tested. This process is relatively simple, but is not without its risks, as the samples used have to be collected by an experienced professional, which increases the risk of contamination. It is best if the DNA sample is taken directly from the vena cava, which is a small artery at the bottom of your large intestine.

If you take this route for your DNA testing, you will be able to get the results much faster than if you have an unsterilized blood sample. However, you should still read the instructions carefully and follow them to the letter.

DNA Testing From a Swab or Sample Taken From the Inside of a Cheek – This is often called DNA profiling, or mtDNA testing. You can get this done with saliva or hair samples, as long as they are collected from the inside of a cheek. It is important to note, however, that you should never use any liquid or other type of drug to collect your sample. If it is collected from an open wound then the DNA will be diluted, and therefore it cannot be compared to a sample that was taken from an inside of a cheek.

Another thing to note about getting mtDNA testing done from a swab or sample from an inside of a cheek is that it is actually possible to have two completely different DNA profiles when compared with one another. When DNA samples from both sides are compared, they will be compared with another similar sample that is found in another part of the body. Therefore, a single DNA profile will not tell you everything about that person.

DNA Testing From a Swab or Sample Taken From the Outside of a Cheek – This method of DNA testing will give you a single copy of the DNA from one area of the body. This single copy may not always match with another sample from a different area. For example, if the sample came from your cheek, but another sample was obtained from the inside of a cheek, you will get a different result from the outside of the cheek, then a different result from the inside of the cheek.

The only way to be sure that the result you get from a swab or other outside of the cheek DNA sample is completely accurate is if you are doing the test from a particular donor. Unfortunately, this can not be done through blood, saliva or hair samples. You can only test someone’s DNA from a bone, a tooth, or a part of their fingernail. As you can imagine, this makes the tests somewhat time consuming and expensive.

DNA Testing From a Sample From an Embedded in a Tissue – The most expensive, and time consuming way to get your DNA tested are to do an expensive DNA test from a part of the patient body. Although it may not be as accurate as other methods, this method will allow you to obtain the most complete results for your results. It is not possible to know if the DNA will match another sample from the same area, but the information is available.
