A urine protein test is often used to screen for, help evaluate, and monitor kidney function and to help detect and diagnose early kidney damage and/or disease.
To screen for excess protein in the urine, to help evaluate and monitor kidney function, and to detect kidney damage.
In a random urine specimen, a protein/creatinine or protein/osmolality ratio can be used to roughly approximate 24-hour excretion rates. The normal protein-to-osmolality ratio is less than 0.42.(1) For patients less than 18 years of age no reference range has been established.
