DNA testing, also known as genetic testing, is an important tool to gauge a person’s risk for contracting a certain disease. Affordable DNA testing is not much tedious for the person getting tested. At a clinic or a hospital, a sample of the individual’s blood or saliva is collected and lab tests are conducted to indicate the presence of a disease. Affordable DNA testing is essentially a roadmap for predicting the occurrence of medical conditions from Alzheimer’s disease to cancer.

Pros of affordable DNA testing

• Insight – One of the primary reasons people opt for DNA testing is its ability to gauge the presence of a certain disease. A set of doctors specialize in reading the DNA sequence and check for interruptions or disruptions from the DNA test results. This insight is important for doctors as it can tell them about a future problem before it has developed or has shown any initial symptoms. The necessary precautions and treatment can help the individual evade a condition that could be fatal.
• Lesser uncertainty – If you have a fear of developing a certain condition as soon as you encounter minimal symptoms, an affordable DNA testing procedure can save you from the stress of the same. Some conditions can be passed on genetically, testing the DNA sample of your children can help in gauging if the condition is present or not. Doctors and test specialists have said that most DNA tests are taken to determine the possibility of family members being at risk for a certain condition.
• Necessary action – Diagnosing a condition even before its initial symptoms have developed is an advantage that comes with affordable DNA testing. There are certain genes that can be associated with fatal conditions, these genes react to medication and treatment differently leading to new medical conditions, which can be avoided using a DNA test. A DNA test would enable the doctor to take necessary and preventive measures to avoid the development of any new possible medical conditions.
• Possible protection from discrimination – Results of DNA testing will appear in the individual’s medical record. This safeguards them from a variety of discriminations at a workplace or insurance offices. There are multiple anti-discrimination laws such as the Genetic Information Nondiscrimination Act of 2008 that can protect the recipient. This law prohibits employers to promote, hire, or even fire their employee based on that data. Similarly, health insurance companies are prohibited from using the results as pre-existing conditions.

Cons of affordable DNA testing

• Eligibility – Genetic testing is a complex process and is not available to everyone. Yes, you can get DNA testing kits, but the results on them will not be as accurate as the lab and hospital tests. You can only be eligible for a test if any of your family members have encountered a genetic disorder and have been genetically tested themselves. The reason for this is the direction of the test. The human body has seven to ten dysfunctional or altered genes. A history of medical conditions among family members will dictate the attention of the test.
• Not a full-body review – If you believe genetic testing is synonymous with a full-body review, you are wrong. DNA testing is targeted and does not work as a full-body examination. It is important for the doctor to know the purpose of the DNA test. They cannot test for every possible condition on the planet. This will not only cost a lot of money and time, but it could also lead to imperfect test results. For example, a patient whose parents have a history of heart conditions will be tested for BRCA 1 or 2 to gauge the risk of breast cancer.
• Limited information – Even if genetic testing can make us aware of different conditions, the severity of these conditions cannot be determined from these tests. Furthermore, a negative result might not always be concrete, as a single test cannot determine all the genetic changes and abnormalities associated with that disorder. This will only lead to additional tests that can cost a lot more than the initial DNA tests. It is also noted that the treatment strategies for early diagnosis of these conditions are limited.
• Physical risks – Genetic testing follows a relatively sound and simple process, but it might have a few physical risks as well. The risks are fewer, as DNA testing only requires you to submit a sample of your blood or saliva. However, some of the more complex tests can be a lot riskier. Prenatal testing can be particularly risky, as it involves the process of acquiring amniotic fluid from the fetus. The risks of this process could also include a miscarriage.
