实验性的:Allergen extracts
Skin prick test of 4 concentrations of D. pteronyssinus allergen extract, together with a positive and negative control, using 10 mg/ml histamine dihydrochloride solution and a glycerinated phenol saline solution, respectively, will be tested in every patient in duplicate on the volar surface of one forearm. Assessment of the wheal size after 15 minutes. Skin prick test of 4 concentrations of D. farinae allergen extract, together with a positive and negative control, using 10 mg/ml histamine dihydrochloride solution and a glycerinated phenol saline solution, respectively, will be tested in every patient in duplicate on the volar surface of the other forearm. Assessment of the wheal size after 15 minutes. |
