Answer
Hi Bree,



One important test to estimate the extent of kidney damage has been the 24-hour urinary protein estimation. However, this "gold-standard" test gives false results if urine is not collected properly.



To obviate this issue, a spot urine protein/creatinine ratio has been devised. It does not have problems due to urine collection, but at the same time, gives a value equivalent to the 24 hour test.



I am not sure I can comment on the numbers that you have provided. This test is reported as numbers, not percentages.



Sincerely,



Dr. Shah
