CSRF includes these names with the goal of providing patients with as many options possible in their pursuit of an accurate diagnosis when hypercortisolism of any type is suspected. CSRF-confirmed specialists are actively involved in research, are usually connected to academic medical centers, and have typically seen hundreds or thousands of patients. To the best of our knowledge, patient-recommended doctors have successfully tested, diagnosed, and directed them to the proper treatment(s) and can thus be reasonably expected to understand internationally-accepted testing and diagnostic guidelines. If you have a different experience, we would like to hear about it. CSRF does not endorse any particular doctor.
