Sensitivity and specificity of the two sets of PCR primers TH1 and TH2 designed for detecting Helicobacter pylori

ABSTRACT

Two sets of PCR primers, named TH1 and TH2, were designed to detect Helicobacter pylori. While TH2 primer can detect the bacteria in 97% of cases, TH1 primer can detect only the bacteria in 42% of cases. The specificity of both primers was 100%. Therefore, TH2 primer was proved more sensitivity than TH1 primer and had promise in use to detect Helicobacter pylori
