HEMOCYTOMETER Meaning and
Definition
-
A hemocytometer is a specialized laboratory instrument used to count and measure the concentration of cells or particles in a liquid sample, particularly blood. It consists of a thick, transparent glass slide, typically with a grid pattern etched on its surface, and a coverslip. The grid is composed of shallow counting chambers, which are engraved with precision to calculate the number of cells in a given volume of liquid.
To use a hemocytometer, a small volume of the liquid sample is placed on the surface of the glass slide and then covered with the coverslip. The grid pattern allows for the cells or particles to settle uniformly within the chambers, forming a known volume for counting. The sample is then observed under a microscope, and the grid is used as a reference to count the cells present in a specified number of squares. By calculating the average number of cells per square and multiplying it by the appropriate dilution factor, the concentration of cells in the original sample can be determined.
Hemocytometers are widely used in clinical and research settings for various purposes, including blood cell counts, cell viability assessments, and cell culture monitoring. They provide a simple and accurate method for quantifying cell populations, aiding in medical diagnoses, experimental analyses, and quality control processes.

Etymology of HEMOCYTOMETER
The word hemocytometer is derived from combining the Greek word haima meaning blood and the Latin word cytus meaning cell, and the Greek suffix -metron meaning measure. Thus, the etymology of hemocytometer can be described as blood cell measure or device for counting blood cells.
