Case 6, Answer 2b

Excellent. A UPCR will provide a quantitative assessment of the protein loss identified in Roxy's urinalysis. A 2+ proteinuria in conjunction with benign sediment always warrants a second look. If the urine is concentrated or inflammatory cells are present, proteinuria may not be renal in origin, but you would want to recheck at least one more sample to see if the proteinuria was persistent. Roxy has dilute urine AND hypoalbuminemia, so a UPCR is a good next step.
