Abstract

The invention relates to a method and a metachromatic composition for counting leucocytes, more particularly basophils. The metachromatic composition used in the method comprises a water/alcohol solution of a toluidine blue acidified so as to exhibit a pH of approximately 3 to 5. Application: diagnosis of allergies. <IMAGE>
