Overview

There is no specific diagnostic laboratory test for dyspepsia but in the patient with the history of dyspepsia, the laboratory test is used to rule out peptic ulcer bleeding and to document the status of eradication therapy (in terms of treatment failure or success), and to test refractory ulcers.

Laboratory Findings

Initial Laboratory Studies

Patient with a family history of peptic ulcer or there is history of refractory ulcer to treatment :

  • A fasting serum gastrin level can be done to screen for Zollinger-Ellison syndrome
  • If the diagnosis of Zollinger-Ellison syndrome cannot be made on the basis of the serum gastrin level, then next step is to do the secretin stimulation test

Following test can be done to document the residual infection after eradication therapy:[7][8][9][10][11]

  • Urea breath test (carbon 13) tests: This is used to document eradication therapy and should be performed four to six weeks after completion of eradication therapy
  • Stool monoclonal antigen tests-This detect active infection and can be used as a test of cure
