Measurement of small amounts of blood in body products such as a urine or stool sample.
1The immunochemical technique is recommended for fecal occult blood detection in marathoners.
2Each subject completed a questionnaire and a fecal occult blood test.
3The rather asymptomatic patient was addressed to investigate a positive fecal occult blood test.
4The contribution of synchronous adenomas to occult blood loss for screening requires further investigation.
5Summary: Preliminary data on fecal DNA tests show better performance characteristics than fecal occult blood tests.
6The clinical and endoscopic scores, CRP levels, and fecal occult blood results were also significantly improved.
7These five CSF samples were shown to be free of occult blood using a sensitive hemoglobin extraction technique.
8Fecal occult blood testing is a popular screening test because of its simplicity, noninvasiveness, and demonstrated mortality benefit.
9Background: Colorectal adenomas are often detected on mass screening, although detection rates with fecal occult blood tests are low.
10There is no guideline defining the optimal time from a positive screening fecal occult blood test to follow-up colonoscopy.
11A colonoscopy can cost upwards of two thousand dollars, compared to several dollars for a home-based fecal occult blood test.
12In this study, a longer interval to colonoscopy after fecal occult blood test was associated with an increased risk of neoplasia.
13The survey focused on the participants' knowledge concerning the faecal occult blood test (FOBT) and their previous testing history.
14Aim: To determine the effect of anticoagulants and antiplatelet medications on the positive-predictive-value of fecal occult blood test (FOBT).
15For example, flexible sigmoidoscopy should be repeated every five years, or every 10 years if it's combined with fecal occult blood testing.
16With the immunochemical technique, the results evidenced the presence of fecal occult blood in 8 subjects in the first postrace stool specimens.
