The World Health Organization (WHO) defines anemia according age, gender, and altitude based on statistical distribution considerations and by cut‐off points.

Since Hb contains almost 70% of iron in the organism, WHO recommends its measurement to determining prevalence of anemia as screening for iron deficiency (ID) despite that they recognize that anemia is not a specific indication of ID...
