Tests for Urticaria (Hives): When Testing Is Needed
Not every patient needs a full set of tests. The range of tests should be decided by how long the condition has lasted and what it looks like.
During an acute flare
Most cases of acute urticaria (hives) can be assessed from the medical history and a physical examination. Many tests are often not needed. If there are clear signs of infection or a history of medicine use, the doctor will arrange the relevant tests for that specific issue.
When it keeps coming back (chronic)
- Basic blood tests: to look for signs of infection or other clues
- Tests chosen based on symptoms: such as thyroid-related markers, autoantibodies, and others
- Allergen-related tests: whether these are needed is decided together with the medical history
- Other tests: decided by the doctor based on what is found on examination
How to work with your doctor
Giving honest details about how often flares happen, how long they last, photos of the rash, and any medicines you take is more helpful than asking to "test for everything". Hand the results to your doctor for an overall interpretation. It is not advised to judge for yourself based on a single result, or to avoid foods long term on your own.
