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.
