False Negative Fecal Occult Blood Test: Prozone Effect
Dear editor, the fecal occult blood test is the presently widely used screening laboratory test for colorectal cancer. At present, the test is usually based on an immunological diagnostic principle (1, 2). A false positive fecal occult blood is common and widely mentioned in literature. Nevertheless, the false negative is little mentioned in the paper. Here, the authors discuss the issue of the...
متن کاملCorrelation of 16s rRNA with serum levels of the cytokines, TNF-α and IL-1β, in subjects with a positive Helicobacter pylori Stool Antigen test (HPSA)
Introduction: Helicobacter pylori (H. pylori), is a bacterium responsible for upper gastrointestinal tract diseases. The 16s rRNA is a common H. pylori gene which are usually preferred for diagnosis purpose. The aim of this study was to determine the prevalence and abundance of 16s rRNA in fecal samples and also evaluate correlation between the level of 16s rRNA and activities of the cytokine...
متن کاملClinical impact of the immunochemical fecal occult blood test for colorectal cancer screening in Brazil
BACKGROUND Colorectal cancer (CRC) screening programs based on the fecal occult blood test (FOBT) reduce CRC mortality. We carried out an observational prospective study to determine the accuracy of immunochemical FOBTs for the detection of CRC in individuals at average risk for the disease. METHODS This population-based study was performed between April 2015 and January 2016 in two gastroent...
متن کاملImmunochemical Fecal Occult Blood Test for Detection of Advanced Colonic Adenomas and Colorectal Cancer: Comparison with Colonoscopy Results
Background. Fecal immunochemical tests (FITs) have been used for colorectal cancer (CRC) screening in several countries. There is lack of information concerning diagnostic performances of this method in Brazil. Methods. Patients scheduled for elective colonoscopy provided one stool sample one week before colonoscopy. The accuracy of a qualitative FIT for detection of CRC and advanced adenomas w...
متن کاملFecal DNA for noninvasive diagnosis of colorectal cancer in immunochemical fecal occult blood test-positive individuals.
BACKGROUND We aimed to define the potential of the fecal DNA assay as an alternative or in addition to the currently used immunochemical fecal occult blood test (iFOBT) for the early diagnosis of colorectal cancer. METHODS A total of 560 individuals aged 50 to 69 years with a positive iFOBT were recruited from an Italian FOBT regional screening program. Twenty-six were diagnosed with adenocar...
