The blood and iron losses in 12 patients with infection were measured with Cr-tagged autogeneous red blood cells. The daily blood loss ranged from 13.6 to 45 ml with a mean of 26.4 ml. The daily iron loss ranged from 3.56 to 9.94 mg with a mean daily loss of 6.06 mg. There was a definite correlation between the intensity of hookworm infection, the daily blood loss, and the severity of the anemia; there occurred a corresponding increase in the daily blood loss and the severity of anemia as the total worm load increased.

The mean blood loss per day per was 0.26 ml with a standard deviation of ±0.045 ml. The calculated mean daily blood loss per 1000 eggs per gram of feces was 4.47 ml with a standard deviation of ± 1.6 ml. The Cr red cell half-life was markedly shortened in those patients with hemoglobin values under 6.5 g per 100 ml and did not return to normal after deworming and cessation of intestinal bleeding.
