肾脏的主要功能之一是对血液的超滤作用形成原尿,经肾小管重吸收后形成终尿排出体外。正常尿液中可含有少量的蛋白成分,如白蛋白、糖蛋白和β2 微球蛋白等。在肾脏疾病中,不仅有尿蛋白量的改变而且可能存在尿蛋白成分的异常。因此,完全有可能将尿中出现的一些特殊蛋白成分 One of the main functions of the kidney is the formation of the original urine by the ultrafiltration of the blood, which is then excreted through the tubular reabsorption to form urine. Normal urine can contain a small amount of protein components, such as albumin, glycoprotein and β2 microglobulin. In kidney disease, there is not only a change in the amount of urinary protein but also abnormal urine protein components. Therefore, it is entirely possible that there will be some special protein components in the urine
