What is the percentage of hypochromic RBCs (% HRC)?

By William Aird

Measures proportion of RBCs that have a cellular hemoglobin weight of < 17 pg (analogous to the mean corpuscular hemoglobin, not mean corpuscular concentration - in other words, the term hypochromic is misleading). The parameter is available in some automated hematology analyzers. May be helpful for the assessment of iron availability (absolute or functional deficiency) for erythropoiesis.
