A 45-year-old patient presents with epigastric pain, nausea, and bloating. The physician suspects gastritis. Which diagnostic test would be most appropriate to confirm the presence of Helicobacter pylori infection as a cause of gastritis?

Complete blood count (CBC)

Serum amylase test

Fecal occult blood test

Urea breath test

Answer and Explanation

The Correct Answer is D

A.   A complete blood count (CBC) can be helpful in identifying anemia or infection but does not confirm Helicobacter pylori infection.
B.   Serum amylase test helps in diagnosing pancreatitis, not gastritis. It is not appropriate for confirming
H.   pylori infection.
C.   A fecal occult blood test detects hidden blood in the stool, which may be present in conditions like
gastric ulcers, but it doesn’t specifically diagnose H. pylori infection.
D.   The urea breath test is a non-invasive and highly effective diagnostic tool for detecting Helicobacter pylori infection. It helps identify the presence of the bacteria by detecting the breakdown of urea in the stomach, which is metabolized by H. pylori.
