C Based off gold-standard hematology analyzer, hemoglobin per age and sex WHO cutoffs
Children < 5y Anemia Cutoffs (g/dL): Mild (10.0–10.9), Moderate (7.0–9.9), Severe (<7.0)
Children 5-11y Anemia Cutoffs (g/dL): Mild (11.0–11.4), Moderate (8.0–10.9), Severe (<8.0); Children 12-14y & Women (non-pregnant) ≥ 15y Anemia Cutoffs (g/dL): Mild (11.0–11.9), Mod (8.0–10.9), Severe (<8.0); Men ≥ 15y Anemia Cutoffs (g/dL): Mild (11.0–12.9), Mod (8.0–10.9), Severe (<8.0)
