The comparison of PCR with three other methode in detecting helicobacter pylori of gastric mucosa[J]. Journal of Chongqing Medical University, 1998,(1).DOI:
PCR(polymerase chain reaction) method for detecting helicobacter pylori(Hp) of gastric mucosa was established and compared with method of rapid urease test
smear and bacterial culture.164 specimens of gastric biopsy mucosa from 100 patients with duodenal ulcer were examined for Hp.The positive rates of Hp were 63%、62%、59% and55% by PCR. rapid urease test. smear and bacterial culture respectively. There ware no differences among four methods. The sensibility and specificity of PCR wer 95.7% and 97.2% respectively.
