Comparison of total count of white blood cells by peripheral smear and automated machine

Topic: Comparison of total count of white blood cells by peripheral smear and automated machine.

Aim and objectives: To compare total count of white blood cells by peripheral smear and automated machine.

Background: White blood cells (WBCs), also called leukocytes, are an important part of the immune system. These cells help fight infections by attacking bacteria, viruses, and germs that invade the body. White blood cells originate in the bone marrow, but circulate throughout the bloodstream. A Coulter counter is an apparatus for counting and sizing particles suspended in electrolytes. It is used for cells, bacteria, prokaryotic cells and virus particles.

Reason: To check whether the total count of white blood cells obtained by both methods are equal.
