The number of blood cells in a sample can be accurately assessed using a hemacytometer. This American example dates from the 1900s. It consists of a hemacytometer, a Levy counting chamber (essentially a microscope slide divided into squares) and two cell pipettes. A blood sample is diluted and placed on the slide. Cells in each square are then counted by examining the sample through a microscope.

An increase or decrease in blood cells in the blood is analysed to estimate levels of malnutrition or the presence of disease within the body. A low level of red blood cells is called anaemia. A high level of red blood cells is called polycythaemia. This hemacytometer was made in Philadelphia by Arthur Thomas and Company.
