NORD is often contacted by people seeking help for an undiagnosed medical condition. Below are answers to frequently asked questions from patients, families, and caregivers.
Connect with a provider who specializes in the type of care you need in our NORD Rare Disease Centers of Excellence network.
Learn MoreThe National Institutes of Health Undiagnosed Diseases Network is the leading clinical research study for helping undiagnosed individuals. The project has discovered new rare disease.
Learn MoreSome people with an undiagnosed medical condition may have a rare disease. Others may have an unusual presentation of a common disease. Difficulty accessing appropriate medical specialists and testing can delay an accurate diagnosis. Sometimes, people remain undiagnosed even after extensive evaluation and testing, because their symptoms can’t be explained by known medical conditions.
Ask your doctor for a referral to an appropriate specialist. Academic medical centers, such as the NORD Rare Disease Centers of Excellence, bring together experts from various medical specialties to offer comprehensive evaluations and diagnostic strategies, as well as opportunities to participate in research.
We recommend you choose the NORD Rare Disease Center of Excellence closest to where you live that is within your insurance network. NORD cannot schedule or refer patients, but your health care provider can refer you.
If a diagnosis isn’t made after being seen at an academic medical center, talk to your doctor about a referral to a specialized research program for people with undiagnosed medical conditions. A growing number of specialized clinics or programs focus on undiagnosed diseases, including programs affiliated with the National Institutes of Health Undiagnosed Diseases Network (UDN).
Patients in other countries may contact the Undiagnosed Diseases Network International.
Many rare and undiagnosed conditions are caused by gene changes called variants. Genetic testing can sometimes provide a diagnosis, so it’s important to ask your doctor if genetic testing could provide information about the cause of your medical condition. Information about genetic testing is available in NORD’s Resource Library.
Some genetic tests are covered by private insurance and Medicaid. Your doctor or a genetic counselor can help you find out what genetic tests are covered by your insurance and advocate for coverage if they decide that testing is important for your medical care.
NORD offers financial assistance to help pay for diagnostic testing for qualified individuals referred by the Undiagnosed Diseases Network (UDN). Additionally, the NORD Support Helpline may be able to help you find other resources providing financial assistance for genetic testing.
People with undiagnosed medical conditions may benefit from participating in research studies. NORD strongly recommends discussing options to participate in research with your doctor. Research can help identify new diseases, expand our understanding of known diseases, and potentially improve diagnosis and care.

Lastly, if you suspect you may have a specific rare disorder and are seeking a specialist qualified to diagnose it, consider reaching out to nonprofit organizations that serve patients with that disorder. Many maintain networks of qualified specialists that they can refer you to. Search by disorder in NORD’s Organizational Database to find an appropriate organization and their contact information.
