To determine proteinuria, the
protein creatinine ratio calculator takes a spot urine sample. The urine protein creatinine ratio is used to identify people with nephrotic proteinuria and to assess those at risk of kidney disease. Only two variables are necessary to compute the rate of urine protein excretion. You only need to know the urine protein and urine creatinine to calculate UPCR, not the urine volume or output.
