One hundred twenty-five patients with chronic urticaria were evaluated with 11 commonly recommended laboratory and radiologic procedures. Abnormal studies were obtained in 26 (20.8%) of these patients, but the majority of these abnormalities were evident from the initial history and physical examination. These results indicate that, with the possible exception of sinus roentgenograms, these laboratory studies are not likely to be helpful in the evaluation of chronic urticaria unless there are suggestive findings in the history and physical examination. The yield and equivalent charge of diagnosis for each procedure used was also analyzed.
对125例慢性荨麻疹患者进行了11种常用的实验室和放射学检查。其中26例（20.8%）检查结果异常，但这些异常大多在最初的病史和体格检查中就已明显。这些结果表明，除鼻窦X线片外，除非病史和体格检查中有提示性发现，这些实验室检查对慢性荨麻疹的评估可能并无帮助。还分析了所采用的每种检查方法的诊断阳性率及相应费用。
