Physical Challenge Tests: Diagnosing Inducible Hives
Published: Sep 01, 2024
Learn how physical challenge tests help diagnose inducible hives and why they are crucial in identifying specific triggers.
The Purpose of Physical Challenge Tests
Physical challenge tests are used to diagnose inducible hives by exposing the skin to specific triggers like heat, cold, or pressure. These tests help confirm the cause of hives and ensure that the right management plan is in place. They are typically performed under medical supervision to manage any allergic reactions.
How Tests Are Conducted
During a physical challenge test, the skin is exposed to a trigger for a set amount of time. For instance, a cold test might involve placing an ice cube on the skin. If hives appear after the stimulus is removed, it confirms the trigger. These tests are organized to ensure patient safety and accurate diagnosis.
When to Consider Testing
Testing is advised when the cause of hives is unclear or when treatments aren't working. It helps pinpoint the exact triggers and guides specialists in creating an effective treatment plan.
