The detection on the infection with the H. pylori by using molecular test (PCR ) by using the different genes and different sampling in the Al-Ramadi city

Abstract

The study aims at finding the infection of Helicobacter pylori by using the molecular test (polymerase chain reaction ) to finding the genes that most efficient in the diagnosis and the easiest sample in usage . the study collect samples from outpatients who customarily visit the medical sight unit > the collections of the sample include biopsies tissue , stool , and saliva from each patient , as well as , samples were collected from the control group (people who are not infection ) . After fiat the molecular test for biopsy tissue is most efficient when sensitivity of 86% and specificity of 100% for the different genes usage , and the molecular test for stool samples are the sensitivity and specificity 70 % and 100 % respectively , while the molecular test for saliva sampling are not found the positive result
