Methods Allergen skin test solution was provided by Shanghai Medical University, with saline as a negative control, histamine hydrochloride as a positive control. To forearm flexor side, infants and young children can also use the back of the skin prick test. Results were positive for Shanghai mites, house dust, cotton batting, cockroaches, pillow, mold and pollen, all negative 20 cases. Conclusions From one aspect, the various sensitizing factors that cause asthma attacks in this area are described. Skin prick prick test is less painful, easier to operate and more reproducible, but there are still false positives and false negatives. Acupuncture point control is not easy to affect the results, so the results must be combined with clinical analysis
