  • Patent number: 4812402
    Abstract: A method is described for the in vitro determination of hypersensitivity to an allergen. The method consists of adding the allergen to a sample containing basophilic leucocytes from the blood of a patient, and then measuring the amount of degranulation of the leucocytes. The allergen is added slowly and continuously, such that the threshold concentration needed to cause degranulation of sensitized leucocytes is reached sometime during the addition step and is present for a long enough period of time to allow degranulation to occur.
