Study Notes

Eosinophils and Monocytes

Eosinophils increase in response to allergic disorders, skin inflammation, and parasitic infections.
Monocyte levels rise during all types of infections and inflammatory disorders.

Slide Preparation Techniques

For blood smears, hold the slide at a 45-degree angle.
Move the slide rapidly while applying consistent pressure to create an even smear.
Allow the slide to dry before applying methanol for fixation, leaving it for 3 to 5 minutes.
Faster movement results in longer and thinner slides, while slower movement leads to shorter and thicker slides.

Neutrophils

Represent 60-40% of the majority of granular (polymorphonuclear) cells.
Slightly larger than red blood cells with a medium size.
Contain granules rich in histamine (a potent vasodilator) and heparin (an anticoagulant).

Basophils

Comprise a minimal percentage (1-0%) of white blood cells.
Associated with allergic reactions and inflammatory responses.

Eosinophils and Neutrophils Characteristics

Eosinophils and neutrophils are similar in size, falling between small and medium dimensions.
Eosinophils have abundant granules that stain with basic dyes, appearing blue-black, which can obscure the nucleus due to granule density.
