Histamine Releasing Urticaria Test (CURT)

This test can help to diagnose a subgroup of chronic urticaria related to circulating histamine releasing auto antibodies.

Identifying this subgroup of patients has practical implications for their treatment.

Other tests for Chronic Urticaria:(Full blood count, liver and thyroid function, autoimmune antibodies, total specific IgE and some others)
Occasionally screening for allergens (food and airborne) are used if doctor suspects it to be of allergic nature.
