©2013 UpToDate ® Print Email Blood smear too thin Suboptimally prepared peripheral blood smear which is too thin. This low power view shows red cells which appear flattened and "brick like" in appearance. Courtesy of Jackie Mitus, MD. Normal peripheral blood smear High power view of a normal peripheral blood smear. Several platelets (black arrows) and a normal lymphocyte (blue arrow) can also be seen. The red cells are of relatively uniform size and shape. The diameter of the normal red cell should approximate that of the nucleus of the small lymphocyte; central pallor (red arrow) should equal one-third of its diameter.
