Urine β2 microglobulin

Urine & beta; 2-microglobulin test introduction: & beta; 2-microglobulin is produced in lymphocytes and has a small amount in urine. Because of its small molecular weight, it can pass freely through the glomerular filtration membrane. The & beta; 2 microglobulin filtered by the glomerulus is almost completely reabsorbed when passing through the renal tubules. If the excretion of urine & beta; 2-microglobulin is increased, it indicates that renal tubular reabsorption disorder is called renal tubular proteinuria To distinguish glomerular proteinuria from albumin. Urine & beta; 2 microglobulin is of great significance in the detection of nephropathy in clinical urine tests.
