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 film or peripheral blood smear is a microscope slide made from a drop of blood, that allows the cells to be examined microscopically
How should a smear specimen be fixed and why?
Heat fixed; because it kills the bacteria,firmly affix the smear to the microscope slide, and allow the sample to more readily take up the stain.
Why is it often necessary to use a cover slip when using the microscope?
Coverslip is not placed on a microscope but on the stained specimen on slide . This protects objective lens of microscope from getting stain from a wet mount . It also protects permanent slide .
Why is it necessary to excessively rinse the smear with water in experiment identifying bacteria using gram stain?
smear should be rinsed with distill water so that all the small particles attach to the smear will washed away such as some time the crystals of dye are attached to the smear which give the illusion of microbial cell some time, distill water is used because it is free from other microbial cell and ions which can harm the smear.
Do you have information about frog blood smear?
a frog blood smear reveals that its red blood cells are ovoid in nature as compared to the human RBCs that are spherical in nature. i think that's the main difference that u will find with a frog blood smear
What is peripheral smear?
A microscopic observation of a stained, peripheral blood smear (can maybe be used in evaluating blood disorders). http://www.brooksidepress.org/Products/OperationalMedicine/DATA/operationalmed/Lab/PeripheralSmear.htm

How long should the length of a blood smear be on a microscope slide?
About 1 drop should be enough

Heat fixed; because it kills the bacteria,firmly affix the smear to the microscope slide, and allow the sample to more readily take up the stain.
What lab tests can be performed to detect the plague virus?
gram or wright stained smear, immunofluorescent stain and fatty acid, gaschromatography, cultures
What is a pencil cell?
A cell from the peripheral blood smear that has a pencil shape, i.e. long and pointy, under the microscope.

Coverslip is not placed on a microscope but on the stained specimen on slide . This protects objective lens of microscope from getting stain from a wet mount . It also protects permanent slide .
What is the essence of making a thin smear?
The essence of making a thin smear is to spread a sample of cells, bacteria, or other substances onto a slide in a very thin layer. This allows for microscopic examination of the sample, so that individual cells and components can be observed. Making a thin smear involves taking a small sample of the material, suspending it in a liquid, and using a microscope slide to spread the sample evenly across the slide. The sample must be spread thinly enough so that individual cells are visible. When the slide is stained, the thin smear allows individual cells to be identified and counted. Making a thin smear is a fundamental part of many laboratory procedures, such as microscopic examination of blood or body fluids, or bacterial culturing.
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.
What is the medical term meaning stained blood smear is examined to determine the shape of individual red blood cells?
The medical term meaning stained blood smear is examined to determine the shape of individual red blood cells is called a peripheral blood smear. This test is commonly used to assess the morphology and appearance of red blood cells, which can provide valuable information about various blood disorders.
