Genetic testing involves analyzing an individual’s DNA to identify specific genetic mutations, polymorphisms, or chromosomal changes. This information can be used for various purposes, including diagnosing medical conditions, assessing disease risk factors, informing treatment plans, and optimizing your lifestyle and wellness.
There are two main types of genetic testing:
Both types of genetic testing contribute to the growing field of personalized medicine, helping individuals make more informed decisions about their health and lifestyle.
DTC stands for “Direct-to-Consumer,” and in the context of genetic testing, it refers to genetic tests marketed directly to consumers via television, print advertisements, or the Internet. As compared to traditional genetic testing, which is usually conducted in a medical setting and often requires a healthcare provider’s referral. DTC genetic testing kits can be purchased online or in stores. Customers can collect their DNA samples, usually via a saliva or buccal swab, and then send these samples back to a lab for analysis.

Clinical genetic testing involves the laboratory analysis of DNA to identify genetic mutations or variations associated with disease or medical conditions. Unlike DTC genetic tests, clinical genetic tests are typically ordered by a healthcare provider and are used for diagnosing, treating, or assessing the risk of medical conditions. These tests are part of a broader medical evaluation. They are often accompanied by pre-and post-test counseling to help patients understand the implications of the test results for their health.
Genetic testing has revolutionized medicine and our understanding of human health. Examining an individual’s DNA makes it possible to identify diseases and conditions with a genetic component. Here are some types of diseases and conditions that can currently be detected through various forms of genetic testing:
Genetic testing can detect inherited disorders like cystic fibrosis, Tay-Sachs disease, and sickle cell anemia. This process is known as carrier screening. These tests can benefit potential parents who want to know if they are carriers for certain conditions that could be passed on to their children.
Genetic mutations that increase the risk of developing certain cancers, such as BRCA1 and BRCA2 mutations for breast cancer, can also be identified. This can help cancer specialists make decisions regarding preemptive measures, like increased monitoring or preventative surgeries.
Certain genes are linked to an increased risk of heart disease and other cardiovascular issues. Genetic tests can flag these genes, allowing for early intervention and management strategies.
Genetic testing can identify risk factors for neurological disorders such as Alzheimer’s disease, Huntington’s disease, and Parkinson’s disease. However, the presence of these genes doesn’t mean that the person will develop the condition, only that the risk is higher.
Conditions like phenylketonuria (PKU) and galactosemia, which affect how the body processes certain nutrients, can be diagnosed shortly after birth using genetic testing. According to a systematic review published in July this year, 52% of patients diagnosed with metabolic disorders also had a family member with the same condition.
Prenatal genetic tests can screen for conditions like Down syndrome and other chromosomal abnormalities. After birth, newborn screening can identify various conditions, including metabolic disorders and congenital hearing loss, allowing prompt treatment. Diagnostic tests like chorionic villus sampling (CVS) and amniocentesis can establish with over 99.9% certainty whether a fetus has a chromosomal variation.
While not definitive, genetic testing can sometimes assess the risk for autoimmune conditions, helping doctors to piece together a more comprehensive picture of your health risks. For example, celiac disease is a condition where the immune system reacts to a substance called gluten that is found in wheat. This affects the digestive system of gluten sensitive individuals if they consume foods like bread and pasta. The likelihood of developing this disease is closely linked to certain genetic markers, specifically HLA DQ2 and DQ8, which are found in more than 98% of individuals with the condition.
Though not a disease, genetic testing can also provide insights into how your body can respond to certain medications, allowing for more personalized treatment plans. A 2020 review highlighted that genetic factors account for about 95% of the variations in response to drug treatment.
It is important to note that while genetic testing can provide valuable insights into your health, your genetics often is just one piece of the puzzle. Lifestyle, environmental factors, and other variables can also significantly impact your risk of developing many conditions. Always consult with a healthcare provider for a comprehensive diagnosis and treatment plan.
Whole genome sequencing is a comprehensive method for analyzing your entire genetic makeup. The technique involves determining the complete DNA sequence at a single time., by sequencing both the chromosomal DNA and the DNA contained in the mitochondria.Â
By reading the entire sequence of an individual’s DNA, whole genome sequencing can provide detailed information about many aspects of being a human, including inherited traits, susceptibility to certain diseases, and even ancestral history. This data can benefit diagnostic purposes, personalized medicine, and academic research.
We will cover whole genome sequencing in more depth in a future article.
The duration of the genetic testing process can vary depending on the type of test and where it’s being conducted.
DNA testing can cost anywhere from $30 to $350, depending on the report’s details. Most DNA testing companies offer varying plans that cater to people’s budgets. Like other subscriptions, the more you pay, the more access and premiums you receive.Â
LifeDNA offers a DNA test plan for as low as $199, which offers access to 6 personalized wellness reports with over 164 unique traits.
In the United States, the coverage of genetic testing by insurance varies widely and is generally influenced by the type of test and its medical necessity. Tests ordered by healthcare providers for specific medical conditions or to guide treatment decisions are more likely to be covered by insurance. These could include tests for cancer risk, prenatal tests, and tests to diagnose specific genetic conditions.
However, insurance typically does not cover elective tests, such as those for ancestry or general wellness offered through direct-to-consumer (DTC) platforms.
If you’re considering undergoing genetic testing, you must check with your insurance provider to understand what is and isn’t covered. Some insurance providers may require pre-authorization or a letter of medical necessity from a healthcare provider to cover the cost of the test. Here is an enlightening article for further reading on genetic discrimination and how health insurance for genetic testing works.
*Understanding your genetics can offer valuable insights into your well-being, but it is not deterministic. Your traits can be influenced by the complex interplay involving nature, lifestyle, family history, and others.
