Clinical does not have how to detect urine protein the most accurate statement, mainly through the urine protein test to determine. Usually, the urine protein test is suitable for detection mainly for early detection of kidney and other systemic diseases, but also can be used to assess the efficacy of nephrotic syndrome, chronic glomerulonephritis, and is applicable to all healthy people and patients with increased foaming in urine, lumbago, high blood pressure, edema, and so on. Whereas the presence of micro-protein in the urine of a normal person, the test result should be negative, indicated as (-). If the amount of protein in the urine is higher than 0.15g/24 hours, it is called proteinuria, and will mostly be positive in routine urinalysis. However, since positive urine protein may be caused by physiological factors such as mental tension, strenuous exercise, cold, pregnancy, etc., it may also be caused by conditions such as acute and chronic nephritis, pyelonephritis, renal tuberculosis, systemic lupus erythematosus, and diabetic nephropathy. It is recommended that patients with abnormal urinary protein should first exclude physiological factors, and if it is caused by pathological factors, they should consult a doctor in time for targeted treatment.
