Chronic spontaneous urticaria is a common skin disorder that is characterised by recurrent itchy, usually raised rash (wheals) and pruritus, with or without angioedema, which can persist for ≥ 6 weeks.
Doctor will do a number of blood test that will help to find out what is causing your symptoms
-urticaria can be related to more severe autoimmune condition.
-urticaria can have allergic nature and simple avoidance can help a lot.
-urticaria can be related to physical factors (temperature, pressure...)
-urticaria can be induced by exercise.
-sometimes it is not possible to find what causes the symptoms, but than doctor can advice how to achieve better control.
What blood tests are recommended?
New HR-Urticaria test -Histamine release (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: (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.
