SPT: A skin prick test is a simple and commonly used method to identify what substances may be causing allergies in a child. It helps doctors detect reactions to common allergens such as dust mites, pollen, pet dander, or certain foods. The test is usually done on the forearm or back and takes only a short time to complete. During the procedure, tiny drops of different allergen extracts are placed on the skin, and a small, gentle prick is made so the substance enters the surface layer. It is not an injection and causes minimal discomfort, similar to a light scratch. After about 15–20 minutes, the doctor observes the skin for any reaction, such as a small raised bump or redness, which indicates sensitivity to that particular allergen. Parents often worry about safety, but the test is generally safe and well tolerated in children when done under medical supervision. It does not cause long-term side effects. Identifying the exact triggers through this test helps in planning better treatment, avoiding specific allergens, and improving the child’s overall quality of life. Apr 3, 2026
