What Health Information Can a DNA Test Tell Me?
Your DNA contains important clues about your genetic predisposition to certain health conditions. For example, your genes may offer information about whether you’re predisposed toward developing certain types of hereditary cancers or other hereditary diseases. Your genes can also tell you whether you’re at higher risk of diseases that have been linked to DNA, like diabetes and Alzheimer’s.
DNA tests can also provide more holistic health information. You can determine what weight your body is naturally predisposed towards being, for example, or what vitamins you may need in more abundance than the average person. DNA tests may also be able to identify foods you may be sensitive to or whether you’re at elevated risk of high cholesterol.
Make sure to take DNA test results with a grain of salt, however; they are based on correlation and probability. They do not predict every health problem you will have to face, guarantee you will get a certain condition, or ensure that a certain diet will help you lose weight.
How Can a DNA Test Help My Health?
The more you know about your health, the more proactive you can be about staying healthy.
When you know, for example, that your genes predispose you towards high cholesterol or other heart health issues, you can change your habits to eat a more heart-healthy diet or get more exercise. Along the same lines, if a DNA test shows that you are likely to have food sensitivities, you can start to avoid foods that may have been making you feel bad without you even realizing it.
A DNA test can also help you seek preventative treatment if it reveals you are at high risk of developing a hereditary disease. For example, individuals who have genes associated with some cancers can get screened earlier or more frequently for those cancers.
What’s Important to Check When Choosing a DNA Test for Health Problems?
There are many DNA testing companies that offer genetic tests specifically for health, and many of them test the same set of genes. So, when comparing DNA test services, there are a few key factors to consider.
- Cost - Pricing varies widely between DNA testing companies, particularly when it comes to health-related tests. When comparing costs, be sure to consider how many genes are being tested with each service and whether there are any add-on charges for shipping or analysis. In addition, consider the resources you will have available to you to help interpret your results. Budget-friendly tests might include just your DNA results, while more expensive tests could include a consultation with a genetic counselor.
- Accuracy - Most DNA tests are highly accurate when it comes to actually sequencing your DNA. However, testing companies can vary in how accurate they are at predicting specific conditions or predispositions based on your genetic makeup. That’s because some conditions are more complex than others and involve more genes. The more complex a condition, the less accurate any predictions that a company makes are likely to be.
- Privacy - An important factor to consider when choosing DNA test services is what happens to your saliva sample and DNA sequencing data after you get your report. Some companies place an emphasis on user privacy and promise not to share any data without your permission. Other companies don’t have the same focus on privacy and may share your DNA data with researchers or even with insurance companies.
- Speed - The sooner you get your genetic test results, the sooner you can start working to improve your health. So, speed matters when choosing the best DNA test for health, too. Many companies are able to deliver results in a matter of days, but some providers can take several weeks to process your DNA sample.
Are DNA Tests Accurate?
The process of sequencing your DNA from a saliva or other bodily sample is highly accurate. While there is a small chance of error with any DNA test, you can trust most reputable DNA testing providers to accurately report what your gene sequence is.
That said, the process of using DNA data to discern health information can be a bit fuzzier. Some conditions are cut and dry—if you have a specific gene variant, then you either have or are likely to develop a specific condition. Most conditions, however, are less clear. You might have a few genes that indicate elevated risk for a condition, but other genes that indicate decreased risk for that same condition.
For those conditions, health reporting can vary between different test providers depending on how they interpret the data. The best DNA health test providers will explain when an interpretation is more or less certain.

Fascinating Discoveries You Can Make
Medical DNA tests are becoming increasingly more popular as the science behind them becomes more understood. Now that people are realizing all that they can learn from a simple cheek swab, consumers are embracing this new early detection method that offers a fountain of useful, sometimes even life-saving, information.
So, what can you learn from a medical DNA test anyway? Here are a few of the most important discoveries being made with these at-home kits:
Disposition to Genetic Diseases -
Probably the biggest reason for taking a medical DNA test is to determine whether or not you are a carrier of certain diseases or medical conditions. The list of diseases that are being tested for today is impressive and includes:
Sickle Cell Anemia
Age-related macular degeneration
Hereditary hearing loss
Heart disease and cancer are the 2 biggest fatal health risks in the country. With DNA testing, you can find out if you or your kids are at a higher risk for contracting these diseases. Other diseases like Cystic Fibrosis or Sickle Cell Anemia are also genetically transferred, and these kits can tell you if you are carrying these volatile genes as well.
Bringing this down to practical life, many people are using these results to make important decisions about their future. For example, couples who discover that one of them is a carrier of these genes are opting to use IVF to conceive, preventing these genetic diseases from being passed on to their children.
Other Genetic Health Risks or Traits
In addition to life-altering diseases and prevention, DNA tests can help you see other genetic health traits you may have inherited. Things like lactose intolerance, sensitivity to certain types of food, high cholesterol, and propensity toward obesity can also be uncovered using a simple at-home kit. Using this information can help you make small changes that will make a huge difference in your life, energy levels, and overall health.
Your Blood’s “Age” - One of the most interesting uses for medical DNA tests, today you can actually see how old your blood is. Well, not literally how old it is, that’s obvious. But these tests show you how well your blood is aging by measuring telomere degradation.
Nutrition & Weight loss - Finally, medical DNA tests are becoming increasingly more popular for nutrition and weight loss guidance. These tests can give you invaluable insight into the way your body works based on your genes, what type of exercise programs will work for you, and how you should be eating to optimize your nutrition for health and weight loss. This is a real breakthrough in the weight loss industry because it is finally giving dieters a personalized approach to fitness and healthy eating that can yield positive results.
How These Tests Gather the Health Info
DNA health tests work by first gathering a sample from the customer, typically either through a saliva sample or a cheek swab. Lab technicians then begin combing through the sample to find clues about your health, what is known as “genotyping.”
One way the tests gather information is by looking at your Single Nucleotide Polymorphisms (SNP), which are variations in your DNA that can be compared to other people's DNA and possibly indicate the presence of a gene associated with a particular disease or physical condition.
Different variants in DNA can indicate all types of potential health conditions, which you may have inherited from your parents. It’s also worth noting that there is a wide variety of diseases which may not be predictable by looking at DNA variants.
Supplements and Recommendations
In addition to predictions of your personal health issues, many companies can also recommend fitness regimens that work for your genetic makeup, or which are more likely to provide optimal results for someone with your genes.
By pinpointing physical traits which are indicated by your DNA, these tests can also recommend a diet that could work better for you. Your genes can indicate a number of things from how your body handles lactose to how it metabolizes alcohol or caffeine, giving you an idea of foods you may be better off avoiding.
Once the lab has created a profile of your health and the issues you may or may not face, it can create a customized recommendation for supplements. With Vitagene for instance, if your test shows that you have problems with blood pressure or that you’re at risk of obesity, it can provide you with monthly supplements to help counter these issues. These tests can also show which supplements your body may have trouble metabolizing or which are unnecessary - so you could potentially stop shelling out cash for pills you don’t need.
With some companies, in addition to dietary assessments and supplements, you can also receive a consultation from a nutritionist who will go over your test results and tell you how it translates to your daily life.
How Reliable and Accurate is the Health Info?
DNA testing companies use a wealth of scientific know-how and precision techniques to analyze your samples.
That said, many nutritionists and scientists dispute the extent to which these tests can create a quick-fix solution, arguing that when it comes to eating and exercising, the importance of balanced meals and regular exercise are basically universal, regardless of the results of a DNA test. In other words, test or no test, you’ll always be better off if you don’t smoke, eat a balanced diet, get ample sleep, and exercise regularly.
Some medical professionals also warn that tests can cause users to worry about potential health risks, without having first seen a doctor who could potentially allay those fears.
Take it With a Grain of Salt
There is a wealth of rigorous scientific know-how that goes into DNA health testing, but the field is still relatively new, and accuracy will continue to grow in the near future. These tests can give important indications about your genetic background and health concerns, but they should not be a one-stop solution. You still need to regularly visit your doctor, and speak to a trained health professional before making any serious life changes.
