Corrected reticulocyte test plays so many roles in our daily life, such as evaluating bone marrow’s ability of producing red blood cells (RBCs), distinguishing various causes of anemia, etc. It can gives an indication of the existence of a disease that may have not been diagnosed yet.
Reticulocytes are newly produced, relatively immature red blood cells (RBCs). reticulocytes in the blood reflect a recent bone marrow function or activity.
The normal ranges for healthy adults should be between 0.5% and 1.5% in the blood; The normal ranges for newborns should be between 3% and 6% in the blood.
However, the results must be interpreted with other test results like RBC count, hemoglobin, hematocrit, or full CBC. Common test results may be as follows:
High reticulocyte count with low RBCs, low hemoglobin and low hematocrit may indicate conditions like hemolytic disease of newborn, hemolytic anemia, bleeding, etc.
Low reticulocyte count with low RBCs, low hemoglobin and low hematocrit may indicate conditions like iron deficiency anemia, aplastic anemia, severe kidney disease, endocrine disease, pernicious anemia, alcoholism, etc.
