Urine albumin generally has the clinical significance of reflecting the degree of glomerular damage, and is the most important detection index for early kidney disease. Therefore, urine albumin is commonly used clinically to monitor the occurrence of kidney diseases, such as hypertensive kidney damage, diabetic nephropathy, urinary tract infections and so on. Urine protein is one of the important tests of routine urinalysis, which is important for the diagnosis of kidney diseases. However, the laboratory generally adopts qualitative testing and uses it as a screening test with low sensitivity. A very small amount of albumin is present in urine under physiologic conditions. When a large amount of urinary albumin is present, the possibility of hypertensive kidney damage, diabetic nephropathy, urinary tract infection and other diseases should be considered. 1. Hypertensive renal damage: Urinary albumin is higher in hypertensive patients than in normal people, and is usually positively correlated with elevated blood pressure. Urinary albumin can be used as an important risk factor and sensitive indicator for predicting hypertensive kidney damage and other diseases. 2. Diabetic nephropathy: the earliest clinical sign of diabetic nephropathy is a persistent increase in urinary albumin excretion rate, and microalbuminuria. 3. Urinary tract infection: urinary tract infection will also increase the albumin content in the patient’s urine to a certain extent, so urinary albumin can also be used as an indicator of renal function damage after systemic or local inflammatory reaction. If the urine albumin is abnormal, it is recommended to consult a doctor in time, follow the doctor’s instructions for further examination, and standardize the diagnosis and treatment under the guidance of the doctor.
