Pro is the medical abbreviation for urine protein, we will do a routine urine examination during the normal medical checkup, which includes the urine protein pro test. A normal person’s urine protein is negative, but if there is a positive Pro, which means that the urine contains urine protein, it is time to go to the hospital to the nephrology specialist for further clarification of the cause. For the formation of urine protein, there are generally two categories: physiological and pathological. Physiological, often seen in patients after strenuous exercise or infection fever, urine protein is transient, often after the disease is controlled urine protein can subside on its own. Pathological urine protein, such as glomerulonephritis, secondary urine protein, such as diabetic nephropathy, multiple myeloma and other factors that cause urine protein, we must actively identify the cause, symptomatic treatment, and if necessary, a kidney puncture biopsy.
