Diagnosis of Urticaria
Your medical history and a thorough examination by your physician are usually sufficient to diagnose Urticaria and no tests are usually required for this. However, to detect the cause of your Urticaria, your physician may ask you to get certain tests done such as:
Allergy tests: To check if the Urticaria is related to specific allergic triggers
Blood tests: Tests to rule out thyroid disease, other auto-immune diseases, etc.
You can help your physician in effective diagnosis and treatment by keeping a diary to track activities, drugs, foods, etc. that trigger your Urticaria.
