DNA tests help you to trace your family lineage and identify the origins of your ancestors. You can also create links with other relatives online you may never imagine being close to you. There are mainly three types of DNA tests, and they can be used for various purposes.
The primary purposes of these major DNA tests include identification of your ancestry and testing your paternal and maternal lines. Other tests deal with health issues and try to establish certain conditions that may be hereditary. The three criteria include the following:
Common Features Of DNA Tests
Interestingly, these major DNA tests share many similarities. For instance, they rely on databases obtained from previous DNA tests. They also use almost similar testing methods and kits. There are different things you should know about DNA testing kits before you undertake the actual analysis. As such, you should know the following 13 things about DNA testing kits.
1. Individual DNA Testing is Simple
You only need to spit a sample of saliva in a test tube then seal it and send to the laboratory for testing. You will get your results in a period of about six to eight weeks, and you can access them online.
The level of accuracy of the testing method depends on the company that you choose for the DNA test. However, the three major companies claim that their testing methods are about 99.9 % accurate and this is plausible. You are guaranteed accurate results.
3. Search For Genetic Variations
The companies that conduct DNA testing are mainly concerned with identifying genetic variants. The building blocks of DNA are called nucleotides consisting of four letters (A, T, C, and G). The information is your genome, and it helps to identify a sequence of genes from the database.
4. Information Can be Limited
The companies use data from various populations with your genes to determine ancestry. In some cases, the data may be limited, but they use the closest links. Some groups have no adequate representation.
5. DNA Gives You Distant History
Mitochondrial Eve who lived in Africa about 200, 000 years ago is the root of all human beings today. From there you can trace your family branches and get to know the origins of your ancestors. For the maternal line, this test is useful.
6. You Can Identify Relatives You do not Know You Have
You can uncover family secrets and identify certain relatives you do not know you have. Adopted people usually grow up thinking that their foster parents are their real ones, but they can discover their true relatives through DNA testing.
7. DNA Help Reveal Your Health Information
Some health conditions are hereditary, and you can get to understand this information through a DNA test. For examples, some diseases pass from one generation to the other. Physicians may require this information to treat certain conditions that are problematic.
8. You get to Know Certain Risks
DNA testing helps you understand certain risks of cancers that pass through other people with similar genes like you. The information helps you to take preventive measures.
9. Other DNA Tests Are For Prescription Only
Your doctor can prescribe a DNA test to examine unique cases like low fertility as well as psychiatric issues. People can make informed decisions about their pregnancy from such tests.
10. Data Sequencing is The Best
Sequencing of data through the use of gene variants helps the companies to identify genes with similarities. Therefore, more data does not mean the accuracy of the results, but it is essential to determine a sequence with similarities of genes.
11. Your Results Can Help in Research
Some companies can ask clients to participate in different studies. The studies are for genetic purposes, and they can help doctors to identify new information that is useful in the medical field. For example, doctors may be interested in studying genes related to specific traits.
12. DNA Test Can be a Source of Income
You can earn money from participating in different researches. The researchers may be interested in studying the link between genes and specific conditions, and the participants get payment in such inquiries. However, the participants should consent to participate in the study so that their information is not used against their wishes.
13. You DNA can Help Solve Security Issues
In case of rape or burglary, the perpetrator can leave DNA that can be used to trace him. The experts can use the DNA to determine the offender through the creation of links with his relatives. However, this scenario can pose ethical questions, but if the need arises, it is helpful.
