The invention comprises a cartridge 10, being a housing (12, see figure 1) defining a recess and holding an absorbent element on which is held an allergen for testing on the skin. An applicator 40 stores multiple cartridges 10a to 10e, and comprises a substantially tubular housing 41. The cartridges 10 are pushed towards an open end 41b of the housing 41 by a cartridge advancement means 52, but are prevented from being ejected by a cartridge retaining means 62. The cartridge retaining means 62 can be disengaged by a user in order to eject a cartridge once it has been used, by pivoting retaining member 48. A following cartridge 10b is simultaneously prevented from moving by secondary cartridge retaining means 64. Releasing lever 48 then allows the following cartridge to move to the front of the applicator 40, by the cartridge advancement means 52. A method for application of an allergen onto the skin of a person by use of an applicator 40 and cartridge 10 is also provided. The allergen may be hair dye, particularly PPD, PADA, PDTA or 3-nitrohydroxyethylaminophenol. |
