Study Notes

Staining a Blood Smear

Staining a blood smear is done to enhance the visibility of blood cells and their morphology under a microscope.

Blood Smear Preparation

Methanol is used to fix the blood cells on the slide, allowing for better adhesion and preservation of the cells.
Creating a monolayer on the blood smear slide ensures that the blood cells are evenly distributed and not overlapping, making it easier to examine them.

Blood Smear Characteristics

A 'feathered edge' on a blood smear slide indicates a well-made smear, with the cells spreading outwards from the center of the slide.

Hematological Disorders Investigation

Blood smears are routinely employed in hematological disorders investigation to provide a rapid and inexpensive way to evaluate blood cell morphology and detect abnormalities.

Malaria Diagnosis

The preferred and most reliable diagnostic method for malaria is the examination of a thick blood smear.

White Blood Cell Differential

A 'manual white blood cell differential' is a labor-intensive process where a microscopist manually identifies and counts different types of white blood cells.
The proportions of different types of white blood cells can be used to determine the presence of infection, inflammation, or other diseases.

Red Blood Cell Examination

Examining the shape, size, and coloration of red blood cells can help diagnose anemia and other red blood cell disorders.

Specialized Stains

Specialized stains in hematopathology are used to detect specific blood cell abnormalities, such as myeloperoxidase for acute myeloid leukemia.

Complete Blood Count Analyzers

Modern complete blood count analyzers can provide automated white blood cell differentials, reducing the need for manual counting.

Anemia Diagnosis

In sickle cell anemia, the morphology of red blood cells is characterized by a sickle shape.

Parasitic Infections Diagnosis

The preferred diagnostic method for certain parasitic infections such as babesiosis is the examination of a thin blood smear.

Thick Blood Smear

A thick blood smear allows the microscopist to screen a larger volume of blood and is more sensitive than the thin film for detecting low levels of infection.
