What this Trial Is About

Researchers are evaluating a digital device called Nexkin DSPT designed to read skin prick tests (SPTs) used for diagnosing allergies. SPTs are commonly used, simple, safe, and quick tests that help identify sensitization to allergens in conditions like bronchial asthma, rhinoconjunctivitis, food or drug allergies, and anaphylaxis. This study aims to validate the clinical usefulness of Nexkin DSPT by comparing its sensitivity and specificity with the standard manual method for measuring wheals from these tests. The study involves using the Nexkin DSPT device, which optically measures the size of wheals from skin prick tests performed on patients. These tests involve applying allergen panels to the skin and measuring the reaction. Both manual and digital measurements of positive (histamine) and negative (NaCl) controls are taken to assess the device's accuracy. The digital method aims to reduce variability, subjectivity, and manual effort, providing quantitative results and faster processing compared to the traditional manual method. Participants will undergo skin prick testing with allergen panels, and measurements of wheal sizes will be recorded by healthcare professionals using both manual and digital methods at enrollment. The outcomes include the size of wheals for positive and negative controls measured by both techniques. The study monitors for adherence to antihistamine restrictions prior to testing and excludes certain patient groups to ensure accurate results. This evaluation seeks to improve allergy diagnosis by potentially offering more consistent and efficient test readings.
