What examination should urticaria do? What is ESR examination?

First, the patients suspected of urticaria caused by rheumatism can be examined for ESR, antinuclear antibody, etc. serum complement determination and skin biopsy are helpful for the diagnosis of urticaria caused by complement activation. If inhalation or ingestion allergy is suspected, allergen test should be performed. If positive, desensitization treatment can be performed.

Second: for cold urticaria, syphilis serum test, determination of cryoglobulin, cryofibrinogen, cryolysin, ice test and antinuclear antibody should be examined. If thyroid disease is suspected, anti microsomal thyroid antibody should be examined.

Third: sunlight urticaria should be checked fecal, urinary porphyrin, should pay attention to the difference with SLE. If the patient is suspected to be related to infection, or has a history of hepatomegaly or hepatitis at the time of physical examination, routine blood examination, hepatitis B antigen, antibody examination, stool eggs, fungi, X-ray examination of the lesion site may be performed.

matters needing attention

Autoantibodies can be detected in autoimmune chronic urticaria. Autoserum skin test was used: routine blood sampling was put into sterile test tube, coagulated for 30 minutes, centrifuged, 100 μ l serum was taken to patients for intradermal test, and normal saline was used as control. If the diameter of local wheal was more than 9 mm after 1 hour, it was positive. Other methods such as histamine release test, Western blot and enzyme-linked immunosorbent assay can be used.
