The Medblue Skin Prick Test Applicator is a sterile, single use disposable, multiple test head applicator used to administer skin test substances to the surface of the skin.

The Medblue Skin Prick Test Applicator is used for the conventional percutaneous application of substance directly onto the surface of the skin of diagnostic allergen extracts for performing skin tests for hypersensitivity reactions in individuals suspected of having allergies.

The Medblue Skin Prick Test Applicator is offered in several configurations with 1, 8, 10 or 12 test heads made of medical grade acrylic (ps158N) material arranged in a symmetrical design. Model AS 113 features a metal tip made of 301 stainless steel. All other models have acrylic tips.

Each of the test heads have a "leg". At the tip of each leg is an array of protruding test points (tines). Each leg has 1, 6, or 9 tines. The tines utilize capillary action to hold the allergenic material for percutaneous delivery when the applicator is applied to the skin. Each leg has a stopper to prevent going deeper than the epidermis thickness.

The test heads are designed to fit into the matching asymmetrical well design of a dipwell tray. The applicator loads the allergen from each well in the tray onto each test head.

When properly applied to the skin, the applicator will leave visible indentations in the patient's skin corresponding to the test heads of each applicator. The applicator is not intended to pierce the skin.
