Urine protein to creatinine ratio
From Ganfyd
A surrogate measure of urinary protein loss and a more convenient alternative to 24-hour urine collection.
The ratio of protein (in milligram) to creatinine (in mmol) in the urine approximates to the amount of protein.[1][2] The approximate conversion ratio is that about x10, i.e. 50mg/mmol is equivalent to about 500mg/day of proteinuria. Values of 3g to 3.5g are regarded as nephrotic syndrome amounts.
