A DNA test is a sort of test wherein a sample of your DNA from your blood, hair, saliva, skin or other parts of your body are analyzed. DNA tests are usually done when a person wants to know his or her family roots, biological parents or child, and even if they need to prove that a crime was committed by a certain person. Skilled scientists compare samples to see if they come from the same person or they are related. Nowadays, people do not have to go to laboratories to have their DNA tested. Companies have produced kits that would allow people to take samples of their DNA in their own homes. A regular kit contains swabs to collect DNA, envelopes for the samples that can be sealed to avoid tampering, and detailed instructions. So, how does a DNA test kit work? Unlike pregnancy test kits, blood sugar test kits and others, a DNA test kit does not give you the result in a few seconds, not even in a few hours. A process can take up to days to get accurate results – not including the shipping time. The length of time would depend on what kind of test should be done. Forensic tests usually take longer than paternity tests.
First, a person usually needs to swab the inside of his or her mouth using a Q-tip that is included in the kit. In some case, a strand of hair or other things that contains a person’s DNA can be collected. The sample is then placed inside an envelope and sealed well before sending. Second, send the sample to the lab. Kits would basically have return envelopes that people can use to send the samples back to the facility for free. Once the sample is received in the lab, it would undergo a series of tests. A forensic scientist would need to isolate the DNA from the cells and are copied through PCR or polymerase chain reaction’. After that, the DNA would be split in certain locations for them to analyze the code and create a DNA fingerprint. The fingerprints are the ones that they use to compare with another DNA and see if there is a match.
If the test is only to determine ancestry, the test will just find out where your ancestors are from based on the structure of the DNA. After the scientists are sure that they have 99% to 100% accuracy about the DNA sample submitted, they then send the results to the person. The sending process would also depend on how the person prefers to receive it. Usually, companies do not recommend sending results by phone. A customer could choose whether results should be sent through mail, email, or even on a certain internet website. Although using DNA test kits give perfect accuracy, some courts and cases do not accept results that do not come from certain labs or services which are mandated by the court. Whether you just want to know about where your ancestors are from, or who your biological parents are, it is important to know which company the kits are coming from.
