A diagnosis or differential diagnosis is determined and discussed with the family once all the information is gathered. Additional laboratory or other medical tests may be suggested to confirm or rule out a diagnosis. Following the clinic visit, the family may receive a counseling letter, written by the genetic counselor, outlining the information discussed during the visit. A medical report is sent to the referring health care provider and others at the family's request. Fact sheets, brochures and other publications that address common questions and provide further information on some specific conditions and disorders. Referrals to support groups, as available, are made.
