How much urine albumin is normal?

Urine microprotein test 24 hours less than 40mg is normal. If it exceeds this range, it indicates that there is pathological proteinuria, which needs to be comprehensively judged according to the test results, renal function of the patient, urinary system B ultrasound, etc. It is also necessary to further check the patient's complement series, and autoimmune series, etc., to rule out whether there are related immune nephritis changes. Kidney damage can show increased protein content in urine, such as glomerular damage can lead to increased protein leakage, showing a large amount of proteinuria. Renal tubular disease can show increased protein leakage, but 24 hours quantitative less than 2 g. If there is some postrenal obstruction, or drug-induced kidney damage, or a high-protein diet, which can lead to varying degrees of proteinuria, urine protein quantitative testing and related renal function testing are required to determine whether further treatment is required, or continue observation.
