Urticaria Diagnosis in Adults and Children
The urticaria diagnosis will be made by the physician by asking questions about the patient’s illness history and performing a thorough physical examination. This is so that in the future patients can avoid it. Doctors will ask about when and how the symptoms of urticaria occur and if something new happens such as changes in the environment or eating foods that have never been eaten before.
Blood and skin tests or allergies may need to be done to find out if you are allergic to anything. But more than half of cases of acute urticaria are unknown.
In chronic urticaria, allergy testing is rarely performed because it is rarely caused by an allergic reaction. Some tests performed to determine the cause of chronic urticaria are:
- Calculation of antibody levels in the blood.
- A complete blood test, to check normal levels of normal red blood cells.
- Liver function tests, to detect liver disorders.
- Taking stool samples to see if there is any infection in the intestine.
- Thyroid function test.
- Blood-End Rate Test (LED) to recognize problems with the immune system.
