Among the 306 infants 12 months of age and lesser than 13 months, 72 (23.5%) had anaemia which was defined as haemoglobin <11.1 g/dL (normal reference range is 11.1–14.1 g/dL), 28 (9.2%) had iron deficiency (ID) which was defined as serum ferritin (SF) below normal reference range (6–24 ug/L) in absence of high C reactive protein (CRP), and 24 (7.8%) had iron deficiency anaemia (IDA) which was defined by a combination of three elements: haemoglobin <11.1 g/dL (normal reference range is 11.1–14.1 g/dL), low SF (<6 mcg/L) and absence of high CRP (reference level is normally less than 5 mg/L).
