The Protein & Creatinine Ratio, Spot Urine Test is a urine test used to measure the amount of protein present in urine compared with creatinine levels. It helps detect abnormal protein leakage from the kidneys and is commonly used for evaluating kidney health.
This test provides an accurate assessment of kidney function without requiring a 24-hour urine collection and helps identify conditions such as proteinuria, kidney damage, diabetic kidney disease, and hypertension-related kidney changes.
1.Protein/Creatinine Ratio
The calculated ratio indicates the amount of protein being lost through urine and helps assess kidney filtration function.
2.Urine Protein
Protein levels in urine help identify abnormal protein leakage caused by kidney damage or other conditions.
3.Urine Creatinine
Creatinine is a waste product produced by muscles and filtered by the kidneys. Measuring it helps adjust protein levels according to urine concentration.
Also known as: Urine Protein Creatinine Ratio (UPCR), Spot Urine Protein Creatinine Ratio, PCR Urine Test
The Protein & Creatinine Ratio, Spot Urine Test evaluates the relationship between protein and creatinine levels in a single urine sample.
Healthy kidneys filter waste products while preventing excessive loss of proteins into urine. When the kidney filtering system is damaged, proteins such as albumin may leak into urine, which can be an early sign of kidney disease.
By comparing urine protein with urine creatinine concentration, this test estimates daily protein loss and helps doctors assess kidney health more conveniently than a 24-hour urine protein test.
The Protein & Creatinine Ratio (PCR) test measures:
The test is useful for detecting:
A Protein & Creatinine Ratio, Spot Urine Test may be recommended for:
The test requires a urine sample collected in a sterile container.
Before sample collection:
| Parameter | Normal range |
|---|---|
| Urine Protein | Low or negative |
| Urine Creatinine | Depends on muscle mass, age, and hydration status |
| Protein/Creatinine Ratio | Generally less than 0.2 mg/mg in adults |
| General interpretation | |
| Normal Range | Minimal or no significant protein loss |
| Increased | May indicate proteinuria or kidney stress |
| High Levels | May suggest significant kidney damage requiring further evaluation |
| Note | Reference ranges may vary between laboratories. Results should be interpreted along with kidney function tests such as Serum Creatinine, eGFR, and urine analysis. |
Reference ranges can differ between labs. Your report shows the range used by the lab.
It is a urine test that measures the ratio of protein to creatinine in a urine sample to assess kidney health and detect protein leakage.
No, fasting is generally not required for the Protein & Creatinine Ratio Urine Test.
Small amounts of protein may occasionally appear in urine, but persistent protein leakage may indicate kidney problems or other health conditions.
A high ratio suggests increased protein loss through urine and may indicate kidney damage, inflammation, or other conditions affecting kidney filtration.

Benefits of the Protein & Creatinine Ratio Test:
The spot urine Protein/Creatinine Ratio provides a convenient estimate of protein loss and is commonly used as an alternative to 24-hour urine collection in many situations.
Yes. Diabetes can damage kidney filters over time, causing protein leakage into urine. Regular monitoring helps detect diabetic kidney changes early.
Testing frequency depends on your health condition. People with diabetes, hypertension, or kidney disease may require regular monitoring as advised by their doctor.
