Simply tell your doctor you have read of the urine 5-HIAA as a measure of carcinoid tumor function and octreosdan want it done. If the carcinoid was greater than 1. Bananas and other serotonin containing food need only be avoided when collecting urine for 5HIAA testing. If negative, do an OctreoScan to search for tumor foci not seen by the other imaging techniques.
