Laboratory diagnosis of gastrinoma 2. a prospective study of gastrin challenge tests

Laboratory diagnosis of gastrinoma 2. a prospective study of gastrin challenge tests

Mayo Clinic Proceedings 57(4): 219-226

A prospective study of the value of secretin, Ca and meal gastrin challenge tests for the diagnosis of gastrinoma indicated that the secretin test may be valuable. The Ca test was equally valuable but is time-consuming and may cause side effects. New criteria for interpretation of these tests were based on peak responses to the challenge. Patients with hypochlorhydria and hypergastrinemia could be identified without the use of gastric analysis. This prospective study reflects the current pattern of clinical practice at a referral institution where patients with gastrinoma, an unusual condition, are seen with regularity. The criteria proposed for interpretation of these tests are simple and could be applied to individual patients in whom a gastrinoma is suspected.
