β_2-m的放射免疫分析在观察许多疾病的疗效、预后估计及诊断方面均有一定意义。例如上、下尿路感染的确定,肾脏功能的判断都优于常规检测项目;肾功衰竭病人及尿毒症病人做血透和腹膜透折前后观察血β_2-m的变化,可作为透析疗效观察的一项指标,还有肾移植的成败预测。此外,亦可用来协助造血系统疾病的分期、分型及疗效观察,肝脏疾病炎症活动程度的监视,恶性肿瘤的诊断和预后估计等。
The radioimmunoassay of β_2-m has some significance in the observation of efficacy, prognosis and diagnosis of many diseases. For example, the upper and lower urinary tract infections are determined, and renal function is better than the conventional test items; renal failure patients and uremic patients do before and after hemodialysis and peritoneal permeation of β_2-m changes in blood can be used as dialysis efficacy An indicator of the success or failure of a kidney transplant. In addition, it can be used to assist in staging, classification and efficacy of hematopoietic system diseases, monitoring the degree of inflammatory activity in liver diseases, diagnosis and prognosis of malignant tumors.
