血清及尿的β2─微球蛋白（β2─MG）测定最先运用于肾功能检查，被认为是一种比血清肌酐更敏感的内生物质。以后血β2─MG的测定在呼吸、消化道疾病和肿瘤中亦有报告。为了解病毒性肝炎患者血中β2─MG的变化，我们对76例肝炎患者进行血β2─MG测定，并与30例正常人对照，初步
The serum and urinary β2-microglobulin (β2-MG) assay was first used in renal function tests and is considered to be an endogenous substance that is more sensitive than serum creatinine. Blood β2 ─ MG after the determination of respiration, gastrointestinal diseases and tumors are also reported. To understand the changes of β2-MG in the blood of patients with viral hepatitis, we measured blood β2-MG in 76 patients with hepatitis and compared with 30 normal controls
