Protein (urine):- Protein:creatinine ratio (PCR) or 24 hour urine protein

Clinical Chemistry

---

Description

Urine protein can be measured in a number of formats: To detect and identify proteinuria in non-pregnant patients, use albumin:creatinine ratio ( ACR ) in preference, as it has greater sensitivity than PCR for low levels of proteinuria. For quantification and monitoring of high levels of proteinuria ( ACR 70 mg/mmol or more ), PCR can be used as an alternative. ACR is the recommended method for people with diabetes ( NICE CG182, 2014 ). PCR can be used as an alternative to 24 hour urine protein in monitoring renal patients.
