Diagnosis of acute gastritis

How is acute gastritis diagnosed?

In cases of food poisoning or viral conditions, acute gastritis can be quickly diagnosed by means of acquiring a thorough history of the patient’s condition.

In other cases, when acute gastritis has other causes, the doctor may order the following tests:

  • Complete blood count (CBC)
  • Blood, breath, or saliva test (to check for H. pylori)
  • A fecal test (to check for blood in the stool)
  • Fibrogastroscopy
  • X-Ray of the stomach (after ingesting contrast dye)
