Anemia prevalence in a population is determined by the percentage of individual cases below a recommended reference value of the hemoglobin concentration, which may be adjusted for altitude and smoking status. The primary method for assessing anemia is through measuring hemoglobin and comparing the value to set thresholds based on age, sex, and physiological status (pregnancy, lactation, etc.). However, other indices of nutrient status are relevant, and are needed to provide a comprehensive picture.

Automated devices used to measure hemoglobin in venous blood are considered an appropriate reference standard for hemoglobin measurement. However, portable devices, such as the HemoCue device (HemoCue®, Angelholm, Sweden), may be more suitable for field use if the blood sample is of good quality. Among other factors, the mode of blood collection (venous or capillary, single-drop, or pooled capillary blood) affects hemoglobin measurements in different contexts.

Discrepancies in the determination of hemoglobin concentrations could have a substantial effect on the estimation of anemia prevalence, especially in population surveys.
