You may have heard the term DNA testing a lot of times. This is very commonly heard in news and movies where the identity of the person has to be validated for a very important reason. Actually, this is done through comparison of DNA fragments. And for those who still don’t know, DNA is the “genetic loci” or the blueprint of a person that links a child to the parent. The child received half of both his parent’s DNA in a less random process.


To check for the person’s DNA, you need to use the collection swab from the DNA test kit, making sure not to touch the tip of the cotton. The person needs to open his mouth very wide so the swab can be inserted. The cotton has to be rubbed firmly back and forth as well as up and down inside one’s cheek. The process needs to be done for a span of 30 seconds. Once the swab is removed from the mouth, it has to be placed directly into the sample envelope which has to be labeled this properly.

If you opt for the buccal swab process, you need to understand that this collects cell from the insides of your mouth or cheek. And it will require the use of a cotton swab. However, note that there are many ways of doing DNA testing. The reason why buccal swabs are used instead of blood samples is that it is the easiest way to perform the test. Pricking of needles for blood testing is invasive and painful. Buccal swabs are also easier to ship.


Other samples that can be used for DNA test includes hair, blood, amniotic fluid, skin or other forms of tissues. Meanwhile, with the autosomal DNA test, you get to know the person’s en tire genome. It covers 700,000 locations that come with genetic markers which help in identifying the individual. This type of DNA test also checks for paternal and maternal lines of a person. Hence, the discovery will be on both sides of one’s family tree.


Meanwhile, an ancestry DNA test will assess your entire genome. This comprises of 23 chromosome pairs. These are the genetic data coming from both of your parents which are handed down throughout generations.


One reason why some people ignore the idea of going through DNA testing is the fear of its exorbitant cost. Actually, it is more affordable than you thought. If you want to have the best result, go for swab testing which can be availed at only $79. In fact, this is what lawyers, government, physicians and private individuals use for DNA testing.


Samples for DNA test can be obtained through buccal swab, pulling 10-20 hair strands, saliva collection and many other samples. Just take note of the precautions in collecting these samples to ensure a high-quality result.
