The efficiency of preoperative laboratory screening of normal, healthy patients was investigated. Preoperative test results of 1311 consecutive patients were collected. Data on haemoglobin, serum potassium, serum creatinine and serum ALAT were routinely obtained. 736 patients were classified by history and physical examination as normal healthy persons not having any systemic disorder. In this group of patients no clinically relevant abnormal laboratory results were found under the age of 60 years. In the group of 60 years and older a significant number had elevated serum creatinine values.
对正常健康患者术前实验室筛查的效率进行了研究。收集了1311例连续患者的术前检查结果。常规获取血红蛋白、血清钾、血清肌酐和血清丙氨酸转氨酶的数据。736例患者通过病史和体格检查被分类为没有任何全身性疾病的正常健康人。在这组患者中，60岁以下未发现临床上相关的异常实验室结果。在60岁及以上的患者组中，相当一部分人的血清肌酐值升高。
