Reticulocytopenia, also known as an "aplastic crisis" or "marrow failure", is the medical term for an abnormal decrease of reticulocytes in the body. Reticulocytes are immature red blood cells. Reticulocytopenia may be a result of viral parvovirus B19 infection, which invades and destroys red blood cell precursors and halts the red cell production. If infection occurs in individuals with sickle cell anemia[1] or spherocytosis, that will lead to incorporation of two anemia-induced mechanisms: decreased red cell production and hemolysis. The result is a severe anemia (aplastic crisis) which may require blood transfusion.

- 相対的増加:網状赤血球の比率のみ増加。エリスロポエチンによる骨髄への刺激が増加しても骨髄組織が十分に増加しなければ期待する網赤血球増加がみられない(OLM.86)。骨髄組織の要因として、骨髄組織が一部、異常病巣(悪性腫瘍、線維化など)に置換され、残った骨髄組織で代償している場合や、全身的要因として、薬剤、栄養障害、全身疾患により部分的に骨髄機能が抑制されている場合がある(OLM.86)。

- EPOの刺激に対して反応して赤血球の産生は亢進し、網状赤血球が相対的に増加するが、絶対数としては少ない。
