long bone
the rpi is used to assess whether the bone marrow is producing an appropriate response to an anemic state. reticulocyte production should increase in response to any loss of red blood cells. it should increase within 2–3 days of a major acute hemorrhage, for instance, and reach its peak in 6–10 days. if reticulocyte production is not raised in response to anemia, then the anemia may be due to an acute cause with insufficient time to compensate, or there is a defect with red blood cell production in the bone marrow. marrow defects include nutritional deficiencies (i.e. iron, folate, or b12) or insufficient erythropoietin, the stimulus for red blood cell production. reticulocytopenia, or "aplastic crisis", is the medical term for an abnormal decrease of reticulocytes in the body

runner’s macrocytosis is a phenomenon of increased red blood cell size as a compensatory mechanism for increased red blood cell turnover. the impact forces from running can lead to red blood cell hemolysis and accelerate red blood cell production. this can shift the ratio of red blood cells towards younger, larger cells. this shift may be reflected in higher than normal mean corpuscular volume (mcv) values, an indicator of red blood cell size.









































this is not a pathological condition but may indicate a propensity toward iron deficiency anemia due to high red blood cell turnover.
