1. What is Protein Creatinine Ratio?

The Protein Creatinine Ratio (PCR) is a diagnostic test that measures the amount of protein in urine relative to the amount of creatinine. It's used to detect and monitor kidney damage, particularly proteinuria which indicates impaired kidney function.

2. How Does the Calculator Work?

The calculator uses the PCR equation:

\[ PCR = \frac{Protein\ (mg/L)}{Creatinine\ (mmol/L)} \]

Where:

\( Protein \) — Protein concentration in milligrams per liter (mg/L)
\( Creatinine \) — Creatinine concentration in millimoles per liter (mmol/L)

Explanation: The ratio normalizes protein excretion to creatinine excretion, providing a more accurate assessment of proteinuria than random urine protein measurements alone.

3. Importance of PCR Calculation

Details: PCR is crucial for detecting and monitoring kidney diseases, diabetes-related kidney damage, hypertension-related kidney issues, and other conditions that cause protein leakage into urine.

4. Using the Calculator

Tips: Enter protein concentration in mg/L and creatinine concentration in mmol/L. Both values must be positive numbers. First morning urine samples provide the most accurate results.

5. Frequently Asked Questions (FAQ)

Q1: What is a normal PCR value?
A: Normal PCR is typically less than 15 mg/mmol. Values between 15-50 mg/mmol indicate microalbuminuria, and values above 50 mg/mmol indicate macroalbuminuria.

Q2: Why use PCR instead of simple protein measurement?
A: PCR accounts for variations in urine concentration, providing a more consistent measurement than protein concentration alone.

Q3: When should PCR be measured?
A: PCR should be measured when screening for kidney disease in high-risk patients (diabetes, hypertension) or when monitoring known kidney conditions.

Q4: Are there limitations to PCR testing?
A: PCR may be less accurate in people with very high or very low muscle mass, as creatinine excretion correlates with muscle mass.

Q5: How often should PCR be tested?
A: For diabetic patients, annual screening is recommended. For those with established kidney disease, testing frequency depends on the specific condition and treatment plan.
