Reticulocytosis is a condition where there is an increase in reticulocytes, immature red blood cell. It is commonly seen in anemia. They are seen on blood films when the bone marrow is highly active in an attempt to replace red blood cell loss such as in haemolytic anaemia, haemorrhage.

- 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)。
