Abstract
  • 1.1. A simple and reasonably precise chemical method employing the benzidine base-H2O2 reaction for measuring 24-hour fecal hemoglobin excretion has been described.
  • 2.2. Forty-nine men were found to shed 1.9 ± 1.3 ml. (1 standard deviation) of whole blood per day in the feces and 22 women 1.2 ± 1.0 ml. per day. Men showed a significantly greater excretion of blood in the feces than women (P < 0.02).
  • 3.3. The quantitative benzidine test resulted in a 12 to 41 per cent higher apparent fecal blood loss as measured by the quantitative benzidine test.
  • 4.4. Oral ferrous sulfate caused a significant increase (about 1 ml.) in apparent fecal blood loss as measured by the quantitative benzidine test.
  • 5.5. All the data in this study was obtained on subjects on ad libitum diets. It would appear feasible to employ this test as a screening procedure without imposing dietary restrictions.
