Urine Creatinine

Concentration of creatinine in the same urine sample.

Output Unit

Select your preferred output unit for the UPCR result.

Add Patient Information (optional)

The urine protein to creatinine ratio (UPCR) is a key test used to evaluate kidney function by measuring the amount of protein present in the urine compared to creatinine. This ratio helps in detecting early kidney disease, assessing proteinuria, and monitoring patients with conditions like diabetes and hypertension. Our Urine Protein to Creatinine Ratio Calculator is Developed to provide accurate results instantly, allowing users to analyze their kidney health with ease.

What is Urine Protein to Creatinine Ratio?

The protein to creatinine ratio (PCR) in urine helps in estimating the 24-hour urine protein excretion without requiring a full-day urine collection. Instead, a spot urine sample is used, making it a convenient and reliable method for assessing kidney function.

Formula for Urine Protein to Creatinine Ratio

The standard formula for calculating UPCR is:

UPCR = Urine Protein (mg/dL) ÷ Urine Creatinine (mg/dL)

Once the UPCR is obtained, it can be converted into different units such as mg/g, mg/mmol, or g/day, depending on the required measurement.

For 24-hour urine protein estimation:

24-hour Urine Protein (g/day) = UPCR × Daily Urine Creatinine (g/day)

Urine Protein to Creatinine Ratio Normal Range

Category	UPCR (mg/g)	UPCR (mg/mmol)	Clinical Interpretation
Normal	< 200 mg/g	< 20 mg/mmol	No significant proteinuria
Mild Proteinuria	200 - 500 mg/g	20 - 50 mg/mmol	Early signs of kidney disease
Moderate Proteinuria	500 - 3500 mg/g	50 - 350 mg/mmol	Possible kidney damage
Severe Proteinuria (Nephrotic Range)	> 3500 mg/g	> 350 mg/mmol	Indicates severe kidney disease

How to Use the Urine Protein to Creatinine Ratio Calculator?

Enter the urine protein concentration (mg/dL or other available units).
Enter the urine creatinine concentration (mg/dL or other available units).
Select the unit of measurement for results (mg/g, mg/mmol, g/day).
Click Calculate to get an accurate UPCR value.
Review the results to interpret kidney function and possible proteinuria levels.

Urine Protein to Creatinine Ratio Interpretation

UPCR < 0.2 g/g (Normal Range): Indicates no significant protein loss in urine.
UPCR between 0.2 and 3.5 g/g: Suggests potential kidney damage or early-stage chronic kidney disease (CKD).
UPCR > 3.5 g/g: Indicates nephrotic-range proteinuria, which requires immediate medical evaluation.

Final Verdict

The urine protein to creatinine ratio is a vital diagnostic tool for detecting early kidney disease and assessing protein loss in urine. By using our Urine Protein to Creatinine Ratio Calculator, users can quickly determine their UPCR and take necessary steps for kidney health monitoring. If you notice abnormal results, consult a healthcare provider for further evaluation.

Frequently Asked Questions (FAQs)

What is a normal protein to creatinine ratio in urine?

A normal UPCR is less than 200 mg/g (20 mg/mmol).

How do you calculate urine protein creatinine ratio?

The UPCR is calculated by dividing urine protein (mg/dL) by urine creatinine (mg/dL).

What level of protein in urine is alarming?

A UPCR above 3.5 g/g (3500 mg/g) is considered nephrotic-range proteinuria and indicates severe kidney disease.

What is the cut-off for urine protein creatinine ratio?

The general cut-off for concern is greater than 0.2 g/g (200 mg/g), suggesting mild proteinuria.
