Question

danny is a 37 y/o male who returns to the clinic for review of lab results. when he came in a week ago he complained of a \sour\ taste when he belched, and severe pain in his stomach. a serum fasting gastrin level was drawn and sent to the lab. the results were 300 pg/ml. his diagnosis on this basis is: ulcerative colitis crohns disease zollinger - ellison syndrome colon cancer

Explanation:

Zollinger - Ellison Syndrome is associated with high serum fasting gastrin levels. Symptoms like a "sour" taste on belching and severe stomach pain can also be indicative. Normal fasting gastrin levels are usually lower, and a level of 300 pg/ml is elevated. Ulcerative colitis, Crohn's disease, and colon cancer are not typically associated with such high gastrin - related symptoms and elevated gastrin levels.

Answer:

C. Zollinger - Ellison Syndrome
