Protein Creatinine Ratio – Urine

The Protein Creatinine Ratio (PCR) test is a laboratory examination used to quantify the ratio of protein to creatinine in urine samples. It serves as a more accurate method for assessing urinary protein excretion compared to measuring protein concentration alone, as it corrects for variations in urine concentration due to hydration status. The PCR test is commonly used to detect and monitor proteinuria, a condition characterized by the presence of excess protein in the urine. Proteinuria can be an early indicator of kidney dysfunction or damage and is associated with various medical conditions, including chronic kidney disease, diabetes mellitus, hypertension, glomerulonephritis, and urinary tract infections. The PCR test helps healthcare providers evaluate kidney function, diagnose kidney diseases, assess disease severity, monitor disease progression, and guide treatment decisions.
