BACKGROUND: Various methods exist for the assessment of @entity190 in a @entity1 with suspected @entity360 . METHODS: The present study examined the effectiveness and financial implications of a qualitative guaiac-based method (Haemoccult) of @entity1503 and a quantitative measure of haeme-derived @entity7889 (Hemoquant) in 184 @entity1 who underwent assessment of faecal @entity190 by both methods over a three year period during assessment of @entity68 deficiency @entity417 . MAIN FINDINGS: At least one Haemoccult test was positive in 72.2% of @entity1 while Hemoquant was suggestive of significant @entity190 (> 2mg haemoglobin/g faeces) in 29.9%. @entity1 underwent a total of 324 further endoscopic or radiological investigations of which 76.5% demonstrated no abnormality. A diagnosis was reached in 60 @entity1 (32.6%). A significant potential source of @entity360 was found in 48 @entity1 (26.1%). Hemoquant achieved a sensitivity of 62.5% and a specificity of 81.6% while with Haemoccult it was 85.4% and 32.4%, respectively. Hemoquant was normal in 18 @entity1 with significant gastrointestinal conditions including peptic ulcers and @entity1586 . While Haemoccult only missed 7 lesions, two of these were @entity694 . The quantitative nature of the Hemoquant test gave little clue as to diagnosis. CONCLUSION: Neither of the tests examined was ideal but Hemoquant had an overall better performance and further investigation of @entity1 with evidence of @entity190 from this test should be mandatory.
