Test Name:

PROTEIN/CREATININE RATIO, RANDOM URINE

General Information

Lab Order Codes:

UPCR

Synonyms:

Protein Creatinine Ratio, Random Urine

CPT Codes:

84155 – Protein; total, except refractometry
82570 – Creatinine; other source

Test Includes:

Test Indications:

The kidney glomeruli behave as ultrafilters for plasma proteins. Urine total protein can be used to test the effects of treatment in diabetes, nephrotic syndrome and in disease processes where proteinuria is possible. Quantifying proteinuria accurately and precisely is vital in monitoring disease activity in patients
