People whose test results are normal will not be seen further at NIH. Those with high cortisol levels will have repeat urine and saliva tests every 2 to 8 weeks for up to 24 months, and a 1-mg DST every 3 months during routine clinic visits at GWUWMP. People whose increased cortisol is found to be due to another condition besides Cushing s syndrome will be referred for evaluation and possible treatment. Those diagnosed with Cushing s syndrome will have standard tests to identify the tumor causing the disorder, followed by standard medical and surgical treatment.
