Comparison of Difference Histamine Concentration (1, 5 and 10 mg/ml) for Positive Control of Skin Prick Test
In Brief
A clinical study evaluating SPT for Immediate Hypersensitivity. Completed, enrolled 180 participants across 1 site.
Detailed Summary
Skin prick test (SPT) was used for diagnostic test for type 1 hypersensitivity. The efficacy and safety of SPT were proved. The positive control of SPT is histamine. In Thailand, the most common concentration of histamine for SPT is 10 mg/ml. However, in some practice they use other concentration (1, 2.5 mg/ml). This study will find the proper concentration of histamine for positive control use in SPT.
