RBCs are normocytic when the mean corpuscular volume (MCV) is between 80 and 100 femtolitres (fL), which is within the normal and expected range.
To aid with determining the underlying cause of the normocytic anemia, a lab test is done on reticulocyte count.
A low reticulocyte count would signify there is a problem at the level of the bone marrow, which produce the stem cells.
In blood loss, morphologic findings are generally unremarkable, except after 12 to 24 hrs where polychromasia appears.
[4] Patients with disordered RBC production, e.g. myelodysplastic syndrome, may have a dual population of elliptocytes, teardrop cells, or other poikilocytes as well as a nucleated RBCs.
