What is blood smear?
A blood smear is a sample of blood that is spread thinly on a glass slide, stained, and examined under a microscope. It is used to evaluate the number, morphology, and size of different types of blood cells such as red blood cells, white blood cells, and platelets. This test helps in diagnosing various blood disorders and infections.
Is there any difference if the prepared smear is too thick or too thin?
Thin smears of blood are needed to investigate hematological problems or disorders of the blood. It is also used to identify the parasite within the blood. Thick films enables the microscopist to screen the blood of a larger volume. They are more sensitive than the thin film.
Why do you have to use NSS instead of water in preparing fecal smear?
NSS (normal saline solution) is used instead of water in preparing a fecal smear to prevent lysis (rupturing) of red blood cells in the sample. Using water can cause hemolysis, which may interfere with the accurate interpretation of the fecal sample. Normal saline is isotonic and helps maintain the integrity of the red blood cells in the smear.
What causes smudge cells?
Smudge cells are caused by the mechanical disruption of fragile cells, such as lymphocytes, during the slide preparation process for blood smear examination. This can occur due to rough handling, poor staining techniques, or improper smear creation. Smudge cells are often seen in samples with high white blood cell counts and do not represent pathological changes in the cells themselves.
Why are white blood cells in a stained blood smear usually counted at low power under a microscope?
Due to the limited field of vision of microscopes, it is comparatively easier to count the number of white blood cells in a stained blood smear under low power than under high magnification. Although the individual cells would be smaller and thus more difficult to count, there would be more in view at any given time.

What are similarities between the human blood smear and the frog blood smear under microscope?
Numerous differences can be seen between frog blood and human blood. Perhaps the most obvious is the oval shape of the frog erythrocytes rather than the biconcave discs of human blood. Moreover, the frog erythrocytes have a nucleus (here stained blue) whilst human erythrocytes do not. There is less difference in size between the erythrocytes and leucocytes than in human blood. There are no platelets in frog blood.
Shape of a human blood smear?
A human blood smear typically has a thin, elongated shape on a glass slide. The thin layer of blood is spread evenly across the slide to allow for visual examination under a microscope. This shape allows for a clear view of the different types of blood cells present in the sample.
