Skin tests are important aids in the management of patients with inhalant allergy. Their usefulness will be increased if these basic principles are kept in mind: (1) Scratch test should be sufficiently deep, (2) Antigen extracts used for intradermal tests should be fresh enough to insure their activity, (3) Two control tests should be used each time tests are done, (4) Hydroxyzine and promethazine may diminish skin reactivity; therefore, negative skin tests should not be relied upon until repeated in the absence of such medication, and (5) Skin tests for food allergy are quite unreliable, whether positive or negative. Food allergy is best studied by means of elimination trial diets.
皮肤试验是管理吸入性过敏患者的重要辅助手段。如果牢记以下基本原则，其效用将会提高：（1）划痕试验应足够深；（2）用于皮内试验的抗原提取物应足够新鲜以确保其活性；（3）每次进行试验时应使用两种对照试验；（4）羟嗪和异丙嗪可能会降低皮肤反应性；因此，在未使用此类药物的情况下重复试验之前，不应依赖阴性皮肤试验结果；（5）食物过敏的皮肤试验无论阳性还是阴性都相当不可靠。食物过敏最好通过排除性试验饮食来研究。
