The testing apparatus includes a capsule 108 tray and a hand held allergen applicator 104 that facilitates convenient storage and easy application of such allergens simultaneously. The hand held applicator 104 includes a plurality of prongs to administer the respective plurality allergen under the skin of the patient. The allergy testing apparatus provides for efficient pre-wetting of the prongs with respective allergens to save the time that would otherwise be required to apply the respective allergens to each of the plurality of prongs immediately before performing an allergy test. In addition, the apparatus provides for efficient use of the allergen testing materials thereby reducing material costs while limiting the amount of residual, unused allergen.
