Urinary albumin excretion rate is calculated by collecting all urine for 24 hours to determine the amount of protein in the urine and calculate the total amount of protein in 24 hours, also known as 24-hour urinary protein quantification. It accurately reflects the amount of protein lost during the day, which is normally very low because only a very small amount of protein is excreted in the urine each day in a normal body. If a patient goes to the hospital and finds that the urinary albumin excretion rate is significantly higher, it is mainly considered to be caused by kidney diseases, including glomerular diseases, diabetic nephropathy, renal tubular diseases, especially diabetic nephropathy caused by diabetic patients is very common. If you find an increased rate of urinary albumin excretion, you should seek medical attention in a timely manner to identify the cause and then treat it with reasonable medication under the guidance of a doctor.
