Appearance
Diameter
Size of Zone of pallor
of RBC
RBCs appear salmon pink and measure 7 to 8 mm in diameter with a zone of pallor that occupies one third of their center
Giulio Bizzozero describe the platelets as
petite plaques
Loss of oxygen-carrying capacity and is often reflected in a reduced RBC count or decreased RBC hemoglobin concentration
Anemia
increased RBC count reflecting increased circulating RBC mass, a condition that leads to hyperviscosity
Polycythemia
Matches the osmolality of blood; consequently, the suspended RBCs retained their intrinsic mor- phology, neither swelling nor shrinking.
normal saline (1:200 dilution)
Drabkin reagent
weak solution of potassium cyanide and potassium ferricyanide for hemoglobin measurement
the ratio of the volume of packed RBCs to the volume of whole blood
