Get answers for your symptoms

30 million Americans have rare genetic conditions. Patients often have symptoms linked to autism, fibromyalgia, and chronic fatigue syndrome. If you have unexplained symptoms, genetic testing can help you find out why and access better treatment within 8 weeks.

Genetic conditions are not always obvious

Symptoms like developmental delays, chronic pain, fatigue and issues with crawling, standing, or walking are common across many conditions. This is why rare genetic conditions can take years for doctors to diagnose.

The Probably Genetic test covers all ~25,000 genes in your DNA to give you the best chance of finding out what is causing your or your child's symptoms. Learn more about how our tests work.

Genetic testing can help improve treatment

There are numerous approaches for treating and managing the symptoms associated with genetic conditions. Identifying the cause of these symptoms may lead to changes in clinical care.

For example, a study from researchers at Johns Hopkins showed that clinical management can change in up to 55% of patients with neurodevelopmental conditions that receive a positive genetic test result.

Our test is clinical-grade and physician-ordered!

With so many genetic testing companies offering different products, how do you know which one to trust?

Our test is physician-ordered and includes genetic counseling

Your test request and medical history are reviewed by both a genetic counselor and a licensed physician to ensure that the test is right for you. If based on your information the test is deemed appropriate, a physician will order a test on your behalf. Once the results are ready, all of our tests include the option to speak with a genetic counselor to best understand what the results mean for you and your family.

Our test is clinical-grade and your information is protected

Your DNA is sequenced in a laboratory that is both CLIA-certified and CAP-accredited, ensuring the highest quality results.
