Figure 1. Venous hemoglobin values in first-time blood donors and NHANES.

Figure 1

Distribution of venous hemoglobin values for RISE first-time/reactivated donors, RISE repeat donors and the 2005-2008 NHANES subjects. Results for (A) Males and (B) Females are standardized to adjust for differing demographics and smoking habits. Probability density reflects the proportion of each group with a certain value of hemoglobin. The sum of all values (area under the curve) equals 100%.
