Abstract. Helicobacter pylori is now recognized as possibly playing an etiologic role on the development of chronic gastritis, peptic ulcers and adenocarcinoma of the distal stomach. CLO test and polymerase chain reaction (PCR) assay are rapid, biopsy-dependent diagnostic tests for H. pylori identification.

What are the symptoms of H. pylori bacteria?

When signs or symptoms do occur with H. pylori infection, they are typically related to gastritis or a peptic ulcer and may include:

  • An ache or burning pain in your stomach (abdomen)
  • Stomach pain that may be worse when your stomach is empty.
  • Nausea.
  • Loss of appetite.
  • Frequent burping.
  • Bloating.
  • Unintentional weight loss.

When do you read a CLO test?

A specimen contaminated with blood may stain the gel around the edge of the tissue. This is NOT a positive test. Negative test: If the color of the gel is yellow at 24 hours, the test is negative. If unable to read at 24 hours, the test will remain valid for 72 hours after insertion of the biopsy into the gel medium.

What is mild antral gastritis?
