Abstract
Method for determining the presence of a malady in a patient by measuring the degree of reaction of individual types of white blood cells (basophils, eosinophils, neutrophils, monocytes and lymphocytes) in the patient's blood. The degree of reaction of each type of white blood cells is determined by comparing the volumetric size distributions of the types of white blood cells before and after exposure to suspected reactants. Positive results of a change in the volumetric size distribution of the individual types of white blood cells in response to exposure to a specific reactant indicates the presence of a specific malady, such as an allergic reaction to the suspected reactant.
