Analyte [material]
Reticulocyte count
Reference range, target level, or decision threshold

0.5%-1.5%, ie, 5‰-15‰ of erythrocytes
Interpretation of results
↑ Hemolytic and acute posthemorrhagic anemias, supplementation after treatment (iron, folic acid, vitamin B12, erythropoiesis-stimulating agents, after hematopoietic stem cell transplant), after splenectomy
↓ Severe anemia due to decreased erythropoiesis in bone marrow, particularly aplastic anemias and aplastic crises in hemolytic anemias
