    Area of Science:

    • Allergy and Immunology
    • Dermatology
    • Medical Device Technology

    Background:

    • Skin prick testing is a common diagnostic method for allergies.
    • Conventional prick test methods may require significant user experience and specific equipment.
    • Standardized and reproducible results are crucial for accurate allergy diagnosis.

    Purpose of the Study:

    • To introduce and evaluate a new 1.0 mm lancet designed for skin prick testing.
    • To assess the suitability, size, and reproducibility of weal reactions generated by the new lancet.
    • To compare the performance of the new lancet with conventional prick test methods.

    Main Methods:

    • A new lancet with a 1.0 mm point length was utilized for skin prick testing.
    • Histamine chloride (1 mg/ml) and Phleum pratense extract (1 histamine equivalent prick - HEP) were used as test allergens.
