The following is a summary of “Prevalence of Iron Deficiency Anemia and Reference Range of Complete Blood Count, Reticulocyte Parameters in Infants Aged 9–11 Month,” published in November 2022 issue of General Medicine by HP, et al.

A significant worldwide health issue is iron deficiency anemia (IDA). Therefore, it was crucial to establish reference ranges for the complete blood count (CBC), reticulocyte hemoglobin content (Ret-He), immature reticulocyte fraction (IRF), and reticulocyte production index (RPI) to aid in the diagnosis of a disease. For a study, researchers sought to establish a reference range for CBC and reticulocyte parameters in babies aged 9 to 11 months, they intended to determine the prevalence of IDA, the risk factors that affect it, and its prevalence as well as risk factors.

The study was conducted prospectively at 10 Community Health Centers from August 2020 to August 2021.

Over 100 healthy infants between the ages of 9 and 11 months were enrolled in the research (47% males and 53% girls). It was 32% common to have IDA. The mother’s education and employment, maternal parity, family income, and baby’s nutritional condition did not affect the occurrence of IDA (P > 0.05). Hemoglobin (Hb) reference ranges were 11.06 to 14.34 g/dL, 11.10 to 14.31 g/dL, 11.13 to 13.90 g/dL, and 10.57 to 13.65 g/dL, respectively, for P2.5-P97.5, P3-P97, P5-P95, and mean ±2SD. The reference ranges for reticulocyte parameter values were also established in the study.

The study’s reference range for the CBC, Ret-He, IRF, and RPI can be used for healthy babies between the ages of 9 and 11 months as a benchmark.
