Ｂｅｔａ２微球蛋白（β２ＭＧ）是体内细胞合成的一种低分子量蛋白质，合成速度恒定，可从肾小球过滤，被肾小管再吸收并分解。血β２ＭＧ升高可反映肾小球过滤功能受损或β２ＭＧ合成增加。测定血清β２ＭＧ含量是目前判断肾脏功能较灵敏、特异的方法，同时对了解恶
Beta2 microglobulin (β2 MG) is a low-molecular-weight protein synthesized by cells in vivo with a constant rate of synthesis that can be filtered from the glomerulus and reabsorbed by renal tubules and broken down. Increased blood β2 MG may reflect impaired glomerular filtration function or β2 MG synthesis increased. Measurement of serum β2 MG content is currently judged more sensitive and specific renal function, at the same time to understand the evil
