The purpose of this study was to evaluate the performance characteristics of three fecal occult blood tests (FOBTs): the chemical o-toluidine test, the immunochemical OC-Hemodia test, and the immunochromatographic Quick Chaser Occult Blood (QCOB) test, which detect human hemoglobin and transferrin simultaneously in cases of upper gastrointestinal (GI) bleeding. Included were 48 FOBT specimens i...

Dear Editor, Colorectal cancer (CRC) is the most common cancer in Singapore. Between 2008 and 2012, it accounts for 17.5% of cancer in males and 13.6% in females.1 Fecal occult blood test (FOBT) is a useful screening tool in decreasing CRC mortality.2 A study conducted in Hong Kong, found that physician’s recommendation had led to increased FOBT uptake among patients [odds ratio (OR) of 23.5%]....

The annual guaiac or immunochemical fecal occult blood test (FOBT) is one of the five colorectal cancer (CRC) screening regimens recommended by the American Cancer Society (Smith, Cokkinides, & Eyre, 2005). Stool-based deoxyribonucleic acid (DNA) testing for CRC is considered a promising technology (Smith, Cokkinides, & Eyre, 2003). Numerous features of three noninvasive stool tests for CRC are...

There is a great need to detect gastrointestinal tract cancer at an early stage. It is well known that most carcinoma tissues of the gastrointestinal tract contain carcinoembryonic antigen (CEA). Stools are a rich source of cells derived from the gastrointestinal tract. We analyzed total fecal CEA in 60 gastrointestinal tract cancer patients, 20 benign gastrointestinal tract disorder patients, ...

BACKGROUND Timely follow-up of fecal occult blood screening with colonoscopy is essential for achieving colorectal cancer mortality reduction. This study evaluates the effectiveness of two ongoing interventions designed to improve colonoscopy uptake after a positive fecal occult blood test (FOBT) result within Ontario's population-wide ColonCancerCheck program. The first was a revision of maile...

The aims of the present study was to determine whether or not abomasal damages occurs in calves with abdominal distention using by plasma pepsinogen levels and positivity fecal occult blood test (FOBT). In study, 30 (distention group) 15 clinically healthy (control group), aged between 1-90 days, were used. Collected samples all used levels, bovine specific ELISA. Fresh stool also taken from re...

The early detection of colorectal cancer is vital for disease management and patient survival. Fecal hemoglobin detection is a widely-adopted method for screening and early diagnosis. Fecal Immunochemical Test (FIT) is favored over the older generation chemical based Fecal Occult Blood Test (FOBT) as it does not require dietary or drug restrictions, and is specific to human blood from the lower...

Results: In the HIV-infected cohort, 72% (216/298) were screened for colorectal cancer. Colonoscopy was utilized in 45% (98/216) of patients and fecal occult blood test (FOBT) in 44% (95/298). There was no difference between the prevalence of polyps between the HIV-infected and uninfected groups (18% vs. 22%, p=0.42). There was a trend that HIV-infected patients were more likely to have advance...

Colorectal cancer (CRC) has become the third most common cancer in the world. Screening has been shown to be an effective way to identify early CRC and precancerous lesions, and to reduce its morbidity and mortality. Several types of noninvasive tests have been developed for CRC screening, including the fecal occult blood test (FOBT), the fecal immunochemical test (FIT), the fecal-based DNA tes...
