Why Use DNA Tests to Learn About Your Health?

DNA tests are useful in learning about your health, which can help identify the necessary steps or changes in the medical care you or your family receives.

DNA testing is identifying variations or mutations in your genes.1 For instance, it can help diagnose if you have a predisposition regarding certain diseases or if you are at risk of developing specific kinds of cancer.

DNA testing lets you learn whether you have a genetic condition that runs in your family before you even have symptoms. Early detection can help in better management of your health.

DNA testing can also help identify a treatment plan.

The Best DNA Tests for Learning About Your Health and Genetic Risks 11

What Can Your DNA Tell You About Your Health?

Using DNA tests to learn about your health can provide valuable insights into your genetic makeup and its potential impact on various aspects of your well-being. Here are some reasons to use DNA tests for health:

  • Know your genetic health risks – DNA tests can reveal your genetic predisposition to certain health conditions. This information empowers you to take proactive steps to manage and reduce risks.
  • Choose better nutrition for your health – Some DNA tests can detail how your body processes nutrients, which helps you make personalized dietary choices to optimize your nutrition.
  • Create personalized fitness routines – DNA tests can shed light on how your body responds to different types of exercise, helping you customize your fitness routine for maximum effectiveness.
  • Helps with disease prevention – Identifying genetic markers linked to specific diseases allows for early awareness and preventive measures. You can make lifestyle changes and regular check-ups to catch potential health issues early.2
  • Choose more effective medications – Certain DNA tests explain how your body might react to certain medications. Genetic variations can affect how drugs work for you when considering treatment plans.
  • Family awareness – DNA testing contributes to a better understanding of your family's health history. This information is valuable for your health and informing other family members about potential genetic risks.

What to Consider When Choosing a DNA Testing Kit

Choosing a DNA testing kit is critical in learning more about your health. Several factors should be considered to know you are making the proper choice:

  • Purpose or test type – Main reasons for taking the test such as health insights, ancestry, paternity, or a combination
  • Reputation – Credibility of the DNA testing company for reliable results
  • Privacy policy – How the testing company handles and secures your genetic data
  • Database size – Bigger DNA database increases the likelihood of finding relatives and receiving more accurate ancestry and health-related results
  • Turnaround time – How long it takes to process and receive your results from a few weeks to a few months
  • Price – Price of the DNA testing kit, including additional fees for accessing certain features or obtaining more detailed reports
  • Customer support – A responsive and helpful customer support team can address any concerns or questions you may have during the testing process

How Accurate Are DNA Tests When It Comes to Health?

DNA tests are really helpful in understanding your health more. However, no test offers an absolute comprehensive health risk assessment. The actual percentage for accuracy of DNA tests for health is unknown.3

While your genes impact your health, other factors, like nutrition, exercise, environment, and family medical history, are also important.

Consult with your doctor if you are concerned about inherited health issues. Your doctor can provide guidance and personalized strategies for screening, treatment, and lifestyle modifications based on your family history and existing health conditions.

What Are the Most Common Health Conditions DNA Tests Detect?

DNA tests can include screening for certain inherited health conditions, including:

  • Cancer risk – DNA tests may identify mutations in genes such as BRCA1 and BRCA2, which are genetic mutations that increase the risk of ovarian or breast cancer among women4
  • Type 2 diabetes – Genetic factors can contribute to the risk of developing type 2 diabetes, which a DNA test can provide insight into (especially regarding metabolic conditions)5
  • Cardiovascular diseases – Some DNA tests analyze genetic markers linked with an increased risk of cardiovascular diseases such as coronary artery disease, atrial fibrillation, and high blood pressure6
  • Alzheimer’s risk – Some DNA tests can help assess genetic markers related to Alzheimer's disease and other forms of dementia but cannot give a definitive diagnosis7
  • Obesity – There are DNA tests that can help identify your risk for obesity, which allows you to create personalized and more effective nutrition and exercise regimens

Are There Disorders DNA Tests Can’t Detect?

DNA tests can only detect disorders that can be passed on or inherited.

DNA tests can only tell if you have a specific gene variant or mutation. They cannot identify with absolute certainty if you will contract that disease.

Therefore, a DNA test can tell what disease you may be at risk of, but it cannot tell for certain what will happen.

A positive test result does not always mean you will get the disease. A negative result does not mean you have no risk of getting the disease. Health risks can change due to lifestyle choices, environment, and aging.

DNA tests can tell your predisposition but cannot identify how you might show the symptoms of the disease, how severe it can be, or how it will progress.

What Should I Do After a DNA Test?

Whatever the result of your DNA test for health, you should always consult a healthcare professional for guidance. Talking to a genetic counselor is also recommended, as they can interpret the results better.

The Best DNA Tests for Learning About Your Health and Genetic Risks 12

Discussing your results with a professional can help you better understand your potential health risks and the implications of such findings.

Share relevant health information with your family members, as genetic predispositions can also affect them.

What Do I Do If My DNA Test Tells Me I’m At Risk?

If your DNA test tells you there’s an increased risk for specific conditions, work with your doctor for a proactive plan. This may include lifestyle changes, enhanced screenings, regular tests, and other preventive measures.

Can I Still Develop Genetic Disorders Even If My DNA Test Says I’m Not At Risk?


A negative DNA test result may mean you have no genetic predisposition to getting the disease. However, health risks can change due to lifestyle choices, environment, and aging.

Am I A Carrier for Genetic Conditions?

Learning whether you are a carrier for genetic conditions typically involves undergoing carrier screening through DNA testing.

Get a DNA test if you are concerned about being a carrier and have a family history of specific genetic conditions.

Carrier screening can identify whether you carry genetic mutations associated with certain conditions, even if you do not show symptoms.

Consult your doctor and genetic counselor for guidance on the appropriate testing based on your circumstances. Once the results are out, they can also guide you in understanding risks and health management.
