Overview
Laboratory Findings
- Autologous serum skin test (ASST) and basophil activation test (BAT) are two tests that are capable of detecting any autoantibodies against IgE for FcεRI.[1][2]
- Although ASST is not a specific test, positive results can determine active disease, mast cells and basophils activation and possible reduction in basophils.
- Interestingly positive autologous serum skin test (ASST) could be related to better prognosis.
- Moreover positive autologous serum skin test (ASST) seems to be related to slower response to omalizumab.
- C-reactive protein (CRP) is also related to disease activity and response to treatment in urticaria.[3] It's elevated level is associated with positive autologous serum skin test (ASST) and elevated levels of erythrocyte sedimentation rate (ESR), leukocytes, neutrophils and IL-6.[4]
- Elevated level of IL-6 is related to disease activity in urticaria.[4]
