What Are Allergies, Really?

An allergy Diagnostic is your body’s way of mistaking something harmless—like pollen, pet dander, or a peanut—for a dangerous invader. Your immune system overreacts, releasing chemicals like histamine that cause sneezing, itching, swelling, or more serious symptoms like anaphylaxis. Allergies can be seasonal, food-related, skin-triggered, or even hidden in everyday materials.

But knowing you’re allergic isn’t always enough. To treat allergies effectively, it’s essential to know exactly what’s causing the reaction—and that’s where diagnostics play a life-changing role.
