About ABCD risk classification for gastric cancer

Gastric Cancer Risk Assessment Test (ABCD classification) is a method for determining the health status of the stomach of an individual by means of a combination of a pepsinogen test (as a gastric mucosal atrophy marker) and a Helicobacter pylori antibody test for screening H. pylori infections (considered to be the main cause of gastric ulcers, duodenal ulcers, and gastric cancers).

The number of unnecessary endoscopy can be reduced by prioritizing patients based on the risk group of gastric cancer.

The reduction of endoscopy examination to healthy people can contribute to decrease healthcare costs.

Pepsinogen (PG) test

It is a blood test designed to objectively evaluate the health status (degree of mucosal atrophy) of the stomach by measuring the serum concentration of a substance called “pepsinogen”. Many gastric cancer cases are shown to develop subsequent to gastric mucosal atrophy, the extent of which can be estimated using the pepsinogen test, and the test results can be utilized to screen individuals for increased risk of gastric cancer.

H. pylori antibody test

It is a screening test of H. pylori infections of gastric mucosa. When infected with H. pylori, the body produces antibodies against H. pylori (H. pylori antibodies) which are released into the blood. This antibody test is a method for measuring these H. pylori antibodies in the blood of the individual.
