Reticulocyte Count
Reticulocytes are immature red blood cells newly released from bone marrow, measured as a percentage of total red cells. High counts indicate active marrow response to blood loss or hemolysis;low counts suggest marrow failure, iron deficiency, or B12/folate deficiency. The reticulocyte index helps classify the cause of anemia.

What is Reticulocyte Count?
Reticulocytes are immature red blood cells newly released from bone marrow, measured as a percentage of total red cells. High counts indicate active marrow response to blood loss or hemolysis;low counts suggest marrow failure, iron deficiency, or B12/folate deficiency. The reticulocyte index helps classify the cause of anemia.
Why It Matters
Indicates bone marrow red blood cell production rate. Elevated after blood loss or hemolysis;low in bone marrow failure or nutritional deficiencies. Helps classify type of anemia.
