What is the size range of a retic?

Reticulocytes are immature red blood cells released from the bone marrow, and their size is essentially the same as mature erythrocytes. The typical diameter is about 7 to 10 micrometers. This range fits the normal variability seen in circulating retics and corresponds to the standard size of RBCs. So the best choice is 7–10 μm. Options smaller than that would be unusually small for an RBC, and options larger (11–13 μm or 14–16 μm) would suggest macrocytes rather than normal reticulocytes. Early reticulocytes can be slightly larger due to residual cellular material, but not to the extent of those higher ranges.
