Abstract
The invention relates to an allergy test chamber comprising at least one inlet for supplying allergen-free air, especially fresh air, into the chamber. Said chamber is characterised in that the at least one inlet () for allergen-free air is provided with an air flow distribution device (), and in that the allergy test chamber () also comprises at least one inlet () for allergen test particles, such as plant pollen or mite faeces, and at least one outlet () for removing air loaded with allergen test particles from the chamber by means of suction. Said outlet () is arranged at a distance from the inlets () for allergen-free air and allergen test particles. Said air movement principle i.e. introducing air into the chamber, mixing it with a defined quantity of allergens, and removing by suction the allergen-loaded air to another area of the chamber, enables uniformity of the distribution of the allergen particles in the test chamber to be significantly improved, compared with known allergy test chambers wherein allergen-loaded air is circulated in the test chamber.
