Analysis of healthy blood. Computer screen showing the result of an analysis of blood with no signs of infection. This result was obtained from a Coulter counter, which counts and measures the sizes of red, white and platelet blood cells in any given sample. The table to the right of centre displays the number and ratios of the various types of blood cells and other components in the blood. The uppermost line of this table shows the normal number of white blood cells indicating that the body is not currently fighting infection. To see a blood test result indicating infection see image M530/384.
