Protein Creatinine Ratio Calculator

Proteinuria is diagnosed using a drop urine specimen and the protein creatinine ratio calculator. The urine protein creatinine ratio (UPCR) aids in the identification of people with proteinuria in the nephrotic category as well as the monitoring of people who are in danger of kidney damage.

Details on proteinuria and how to compute the protein creatinine ratio can be found in the section below.

The Basic Formula for calculating protein creatinine ratio:

PCR = Protein / Creatinine

PCR means Ratio Protein and Creatinine
Protein means Level of Protein
Creatinine means Level of Creatinine

Urine protein creatinine ratio

Proteinuria is a renowned cause of heart infection and respiratory illness, as well as a determinant of organ dysfunction. Nevertheless, the standard test, a 24-hour urine protein estimation, is identified to be undependable.

A few experts have investigated using a protein creatinine ratio assessment in urine specimens taken over a brief period, or even random (spot) urine samples, because creatinine and protein excretion is pretty consistent all through the day (given that the glomerular filtration frequency is constant).

Protein Creatinine Ratio Calculator: How to calculate protein creatinine ratio

On the protein creatinine ratio calculator, just two parameters are required to calculate the frequency of urine protein excretion. For the computation of UPCR, you only have to establish the urine volume and yield.

Urine protein (measured in milligrams per deciliter) and urine creatinine (measured in milligrams per deciliter).

The protein creatinine ratio is calculated using the given formulas:

Urinary Protein Excretion (G/Day) = Urine Protein / Urine Creatinine

The standard value for urine protein is 15 mg, but the normative value for spot urine creatinine has yet to be determined.

Its worth is determined by a variety of elements, including food, body composition, lean body mass, activity, and so on.

Protein Creatinine Ratio Calculator: Analysis Of The Protein Creatinine Ratio

The below explanation of the protein creatinine ratio should be used, as per Ginsberg et al.

Protein Creatinine RatioInterpretation
Less than 0.2It’s at a normal range
Between 0.2 and 3.5More research is required.
Greater than 3.5It’s at the nephrotic range

Proteinuria can be classified into 3 groups depending on the protein creatinine ratio, as per Kidney Disease Improving Global Outcomes recommendation:

Protein Creatinine RatioClassification
less than 1.5 grams per dayRegular to mildly increased
Between 1.5 and 5 grams per dayRaised slightly
more than 5 grams per dayHardly raised

Protein Creatinine Ratio Calculator: Nephrotic Range Proteinuria

Proteins that ought to stay in the circulation, not the urine, are filtered by the kidneys. Excessive protein in the pee is known as proteinuria.

Protein excretion increases are commonly employed in the early detection of a variety of illnesses, such as preeclampsia, diabetic nephropathy, and nephrotoxicity attributable to drugs.

Nephrotic illness, which is defined by a variety of symptoms caused by renal disease, is linked to chronic proteinuria. Protein in the urine, low blood albumin levels, high blood lipids, and considerable edema are some of the symptoms.

Blood clots, ailments, protein deficiency, and high blood pressure are all possible consequences of nephrotic disease. Treatments for this condition are determined by the actual cause.

Real-Time Demonstration Using A Protein Creatinine Ratio Calculator

Let us just look at an example urine protein creatinine ratio for someone who has these findings

Urine protein concentration is 2 milligrams per deciliter, while

Urine creatinine concentration is 120 milligrams per deciliter.

  1. To determine the protein creatinine ratio, we’ll use the formula below:

Urinary protein excretion (grams per day) = Urine protein / Urine creatinine

  • The equation appears like this following replacing the parameters with the results:

Urinary protein excretion (grams per day) = 2 / 120

  • We can get the following result after solving this simple calculation:

Urinary protein excretion (grams per day) = 0.0167

  • The above protein creatinine ratio is in the standard limit and did not show proteinuria in the nephrotic spectrum.

Limitations on the Protein Creatinine Ratio Calculator

  • Urinary Protein Excretion Estimation (also known as spot urine protein divided by creatinine ratio or protein divided by creatinine ratio) estimates twenty-four-hour protein excretion by calculating the protein/creatinine ratio from an arbitrary urine specimen.
  • The protein/creatinine ratio from a given urine specimen should indicate protein excretion, wiping out the time difference, depending on the physiologic premise that urinary creatinine excretion is consistent if the glomerular filtration rate is fixed.
  • Multiple investigations have confirmed the association with 24-hour protein excretion.
  • Urine samples voided overnight and upon waking to have the lowest correlation.
  • Only in the presence of stable renal function may it be employed.
  • Even in the absence of a reduced glomerular filtration rate, hypertension, or other pathological observations on urinalysis, recurrent proteinuria signals renal illness if albumin is the main element.

Why do you need Protein Creatinine Ratio Calculator

  • Urine sampling for 24 hours is time-consuming, stressful for sick people, and prone to mistakes. By utilizing a single urine test, the Urinary Protein Excretion Estimation eliminates these issues without compromising performance.
  • Proteinuria is a significant predictor for cardiac diseases and kidney illness, as well as an indicator of end-organ damage. In the early diagnosis and verification of kidney disease, identifying an increase in protein excretion has both diagnostic and prognostic relevance.
  • Proteinuria can also be used to measure the efficacy of treatment and the disease’s development.

When should the Protein Creatinine Ratio Calculator be used?

  • Patients that are diagnosed of having a renal illness (to rule out).
  • Patients who have a history of kidney impairment (to assess progression).
  • Patients with low-grade proteinuria but otherwise healthy kidneys (to monitor).

Protein Creatinine Ratio: A Quick Overview

The protein creatinine ratio is an assessment that measures kidney performance and is done as part of a urinalysis with a dipstick urine protein check.

The glomerular filtrate proteins reside in the bloodstream, but when their performance is disrupted, nephrotic syndrome develops, and proteins flow via the urine. Proteinuria that persists shows a renal permeability rise that is excessive. Kidney failure is the most common consequence of long-term proteinuria.

Proteinuria is linked to several illnesses, including kidney illness, polycystic kidney dysfunction, amyloidosis, urinary tract disease, congestive heart failure, glomerulonephritis, and systemic lupus erythematosus diabetes. Pre-eclampsia is linked to higher urine protein levels in expectant mothers.

As a result, even if neglected, people with chronic low-grade proteinuria completely irrelevant to impaired kidney function or a systemic disease are unlikely to have long-term problems.

To minimize or eradicate proteinuria, many nephrologists prescribe an antihypertensive medication, such as an angiotensin-converting enzyme (ACE) inhibitor. Patients with low-grade proteinuria should be checked once a year to ensure that their condition is not worsening and that their kidney performance is steady.


Adults having a urine output of more than 3.5 grams per day are said to have nephrotic syndrome.

Protein excretion of less than 2 g per day, whether as a result of therapy or spontaneously, is linked to a better long-term prognosis.

If you’re unsure about how to determine your protein creatinine ratio, see your doctor.


What is a healthy protein creatinine ratio?

In kids aged 6 months to two years, the typical protein creatinine ratio is less than 0.5, less than 0.25 in kids older than two years, and less than 0.2 in grownups.

Is a protein level of 30 milligrams in the urine considered excessive?

Albumin levels in the urine should be fewer than 30 mg/g. Even if your GFR is at 60, anything above 30 mg/g could indicate renal disease.

What does the protein creatinine ratio mean?

The patient has substantial proteinuria if the urine protein creatinine ratio is greater than or equivalent to 0.28. If the urine protein creatinine ratio is between 0.15 and 0.27, the conclusion is inconclusive, and a 24-hour urine collection is required for further analysis.
