Pronormoblast identification on a smear
Pronormoblast : Basophilic cytoplasm with large, indistinct nucleoli characterize the most immature cell in the erythroid series.
Segmented Neutrophil and Large Lymphocyte on a smear
Segmented Neutrophil on the left
Large Lymphocyte on the right
monocyte and reactive lymphocyte
monocyte :
3-4x larger than a mature RBC
Lower nuclear to cytoplasmic ratio because of increased cytoplasm
Kidney shaped Indented Nucleus with mature chromatin (clumped)
Nucleoli are ...
Differentiating Monocytes from Large Lymphocytes
Top left frame: Monocyte with an irregular outline, gray cytoplasm containing a few azurophilic granules and vacuoles, and a nucleus with an open or lacy chromatin distribution.
Lower ...
Peripheral Blood Smear Examination
An examination at low power (10X ocular, 10x objective) is first performed to evaluate the quality of the smear, ascertain the approximate number of white blood cells and platelets, ...
Spur cell RBC known as Acanthocyte
Spur cell RBC (Acanthocyte)
May be smaller or the size of a normal RBC
Irregular narrow-base sharp projections of red cell membrane (looking like cowboy boot spurs)

Microcytic Red Blood Cell
Microcytic RBC: MCV <80* :
Slightly smaller than a normal mature RBC which correlates to the MCV of <80 fL
pallor is usually present (as opposed to a microspherocyte)
Can be ...
Macrocytic Red Blood Cell
Macrocytic RBC: MCV >100*
Slightly larger than a normal mature RBC which correlates to the MCV of >100 fL
Round to oval in shape (lacks a nucleus similar to the normal RBC)
Cytoplasm ...
