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 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.
How can you identify erythrocytes by using microscope?
Erythrocytes, or red blood cells, can be identified under a microscope by their characteristic biconcave disk shape, lack of a nucleus, and pink/red coloration due to hemoglobin. They are typically smaller in size compared to other blood cells and appear uniform in shape when properly stained and viewed under high magnification.
How are karyotypes prepared and what is the process involved in creating them?
Karyotypes are prepared by taking a sample of cells, usually from blood or amniotic fluid, and growing them in a lab. The cells are then stained to make the chromosomes visible under a microscope. The chromosomes are arranged in pairs according to size, shape, and banding patterns to create a visual representation of an individual's genetic makeup.
What microscope would be used to look at a blood sample?
A light microscope would typically be used to look at a blood sample. This type of microscope has sufficient magnification and resolution to visualize blood cells such as red blood cells, white blood cells, and platelets.
White blood cells are actually white?
White blood cells are not actually white; they appear white under a microscope due to the way they are stained for observation. The name "white blood cells" comes from the fact that they are cells that do not contain hemoglobin, unlike red blood cells which carry oxygen and give blood its red color.
Process in which leukocytes are stained and counted?
The process you are referring to is known as a blood differential test or a white blood cell differential count. During this test, a blood sample is stained with special dyes to help differentiate between various types of white blood cells. These stained cells are then counted under a microscope to determine the relative percentages of each type of white blood cell present in the sample.
How can you observe a white blood cell in a light microscope?
White blood cells can be observed in a light microscope by preparing a blood smear, staining the cells with a dye like Wright's stain or Giemsa, and then viewing them under high magnification. The cells will appear as small, irregularly shaped cells with a dark-stained nucleus and a lighter-stained cytoplasm.
