Diagnosis unknown refers to when a person has signs and/or symptoms of a medical or mental health issue, but doctors cannot identify or diagnose the person’s condition or disorder. Without a diagnosis, or the correct diagnosis, it is difficult to get the correct treatment. People may search for years for a diagnosis especially if they have a rare medical or genetic condition. If the condition is rare, sometimes doctors will not know enough about it to diagnose it correctly. Diagnosing can be difficult if there is not a specific test or set of certain symptoms for the condition. Diagnosis can also be hard if the signs and symptoms a person has are general and could be found in number of different conditions. Sometimes a person’s symptoms may not be the typical or usual symptoms for a certain condition but they still have that condition. Sometimes a person may have a condition which has not been identified before. If you are classified as diagnosis unknown by your doctor, it is best to first get a second opinion. Medical advances are happening all the time and with new techniques, such as whole genome sequencing, more people are able to receive a diagnosis. If you or a family member is consistently given an unknown diagnosis, reach out to a support group which specializes in supporting people searching for a diagnosis. Support groups will not only help you in your effort to get a diagnosis but can also be a great emotional support.
