Urine a1 microglobulin is high

High A1 microglobulin in urine may be caused by kidney diseases such as glomerulonephritis, renal failure, nephrotic syndrome, etc. Under normal circumstances, glomerular filtration function does not expel large molecular proteins from the body in order to maintain protein balance in the body. If the kidneys show damage, it will cause abnormal glomerular filtration function. Large molecular proteins enter the urine, which will cause high A1 microglobulin. The patient should further do 24-hour brain white quantity and renal function test, clarify the cause, and do targeted treatment.
