differential white blood cell count

For example, in laboratory medicine, the sum of the components of the differential white blood cell count must be equal to 100 (since they are all percentages).

Because it distinguishes easily between blood cells, it became widely used for performing differential white blood cell counts, which are routinely ordered when infections are suspected.

The original Alvarado score describes a possible total of 10 points, but those medical facilities that are unable to perform a differential white blood cell count, are using a Modified Alvarado Score with a total of 9 points which could be not as accurate as the original score.
