Answer

The World Health Organization (WHO) criterion for anemia in adults is a hemoglobin (Hb) value of less than 12.5 g/dL. Children aged 6 months to 6 years are considered anemic at Hb levels less than 11 g/dL, and children aged 6-14 years are considered anemic when Hb levels are less than 12 g/dL. The disadvantage of such arbitrary criteria is that a few healthy individuals fall below the reference range, and some people with an underlying disorder fall within the reference range for Hb concentration.
