Your results will indicate whether genetic variants associated with specific inherited conditions have been identified. Some results may show an increased genetic risk, while others may show no medically significant findings in the genes analyzed.
 

Because genetics are only one part of your overall health picture, Marker by Labcorp includes educational resources, a personalized results video, and access to licensed genetic counselors to help you understand what your results mean and what actions you may want to discuss with your healthcare provider.

Yes. Marker by Labcorp includes access to licensed genetic counselors who can help explain your results and answer questions about inherited health risks.
 

Genetic counselors can help you understand what your results may mean for you and, in some cases, your family members. Genetic counselors can also help you prepare for conversations with your healthcare provider and better understand potential next steps.

Hereditary diseases are conditions that can be passed from one generation to the next through genes inherited from biological parents. These conditions are often associated with genetic variants that may increase disease risk.
 

While inheriting a genetic variant does not always mean you will develop a specific condition, identifying these variants through genetic testing can help provide important information about your health risks and support earlier monitoring or prevention strategies.

Personalized, or precision, medicine uses information about your genetics, health history, and lifestyle to help guide healthcare decisions. Genetic testing can uncover inherited risk factors that may not be apparent based on symptoms or family history alone.
 

When combined with other health information, genetic insights may help healthcare providers develop more personalized screening, monitoring, and prevention plans tailored to your unique health profile.

Genetic testing can help you better understand your inherited health risks, make informed healthcare decisions, and take a more proactive role in managing your health. It may also provide valuable information that can be shared with family members who may have similar genetic risks.
 

At the same time, genetic testing has limitations. Results may raise unexpected questions or concerns, and testing cannot predict every health outcome. Because genetics is only one factor that influences disease risk, Marker by Labcorp includes access to licensed genetic counselors who can help you understand your results and what they may mean for you.

Autosomal dominant disorders are inherited conditions that can occur when a person inherits one altered copy of a gene from either biological parent. Someone with an autosomal dominant variant may have an increased risk of developing the associated condition and may also be able to pass the variant to their children.
 

Examples include certain hereditary cancer syndromes and inherited cardiovascular conditions. Identifying these variants through genetic testing may help support earlier screening, monitoring, and risk-management discussions with a healthcare provider.

Genetic testing cannot prevent disease by itself, but it can help identify inherited health risks before symptoms develop. Knowing certain genetic risks may help you and your healthcare provider make more informed decisions about screening schedules, monitoring plans, and preventive care options.
 

Earlier awareness can support proactive healthcare planning and help you take a more informed approach to your long-term health.

When comparing genetic testing services, consider factors such as laboratory quality, the number and type of genes analyzed, access to professional support, privacy protections, and how results are delivered.
 

Some tests focus on ancestry or wellness insights, while others, such as Marker by Labcorp, evaluate genes associated with medically actionable health conditions. You may also want a service that includes genetic counseling support and results you can share with your healthcare provider to support follow-up care.

Results are typically available within 10 to 21 days after your sample arrives at the laboratory. As soon as your results are available, you'll receive an email notification with a personalized video and consult notes. Your full test results will be available in your Labcorp Patient account via your MyLabcorp™ app or at MyLabcorp.com.

A hereditary genetic risk panel may be right for adults who want to learn more about their inherited health risks and take a more proactive approach to their health. It may be especially helpful for individuals with limited knowledge of their family health history or those interested in additional information to support long-term healthcare planning.
 

This test is not appropriate for patients who have had a bone marrow or stem cell transplant, have had a blood transfusion in the last two weeks, have had a liver transplant or are currently being treated for cancer. People with a strong family history of related conditions or known genetic disorders should consult their healthcare provider or a genetic counselor to determine the most appropriate testing.
 

Genetic testing can uncover risks that may not otherwise be known and help support more informed conversations with your healthcare provider about screening, monitoring, and prevention options.
