Overview
There is no specific diagnostic laboratory test for peptic ulcer disease but in the patient with the history of peptic ulcer disease, the laboratory test is used to rule out bleeding and to document the status of eradication therapy and to test refractory ulcers.
Initial Laboratory Studies
- There are no diagnostic laboratory findings associated with peptic ulcer disease
- If there is the history of peptic ulcer disease then following laboratory test are done:[1][2][3][4][5][6]
- Complete blood count
- Liver function tests
- Serum lipase and amylase
- Iron studies
- Some patients with Peptic ulcer disease may have reduced serum ferritin, which is usually suggestive of bleeding which requires further endoscopy to rule out bleeding
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 measure 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
- Urea breath test require the ingestion of urea labeled with the nonradioactive isotope carbon 13 or carbon 14
- Proton pump inhibitors (PPIs) should be stopped for two weeks before the test
- Stool monoclonal antigen tests-This detect active infection and can be used as a test of cure
- PPIs should be stopped for two weeks before testing
- This can be done by following methods:
- Enzyme immunoassay
- Immunochromatography
- Antibody tests
