What tests or procedures can be done to detect hives?

To detect hives, a healthcare provider typically performs a physical examination and reviews the patient's medical history. In some cases, they may conduct allergy tests, such as skin prick tests or blood tests, to identify potential triggers. If the cause remains unclear, a dermatologist may recommend a skin biopsy to rule out other conditions. Generally, diagnosis is primarily based on the appearance of the hives and associated symptoms.
