The urine protein creatinine ratio (urine PCR) has a normal value of less than 150 mg/g.
Urine PCR refers to the ratio of total urine protein to urine creatinine. The concentration of protein in a urine specimen is influenced by the body’s hydration (i.e., the urine specimen may be diluted or concentrated), whereas creatinine excretion is usually constant throughout the day, and therefore urinary creatinine is commonly used to correct for the concentration of urine, expressed as urinary protein concentration/urinary creatinine (urinary PCR).
The normal value of urinary PCR is less than 150 mg/g. Elevated urinary PCR suggests the presence of protein in the urine, which is divided into two types: physiologic and pathologic. Physiological strenuous exercise, fever, etc.; pathologic, including various glomerulonephritis, urinary tract infections.
Patients with abnormal urinary PCR should go to the hospital in time to see a doctor, clarify the cause under the guidance of a professional physician, and follow the doctor’s instructions for standardized treatment.
