A time-saving-modified Giemsa stain is a better diagnostic method of Helicobacter pylori infection compared with the rapid urease test.

The modified Giemsa stain is more simplified and time-saving than traditional Giemsa stain, which is comparable to the traditional one and is confirmed to be better than CLO test using 233 H. pylori-infected patients with gastric disease. In clinical examination, this modified Giemsa stain can be applied to routine examination and provides quick and accurate diagnosis and prognosis to H. pylori-infected patients with gastric diseases.
