🧪 What is Protein Creatinine Ratio (PCR) – Spot Urine Test?
The Protein Creatinine Ratio (PCR) in a spot urine sample measures the amount of protein excreted in urine relative to creatinine, providing an estimate of daily protein loss without the need for a 24-hour urine collection. It is a convenient and reliable marker of proteinuria.
❓ Why is the Test Done?
To:
- Detect and quantify proteinuria, an important sign of kidney damage
- Monitor patients with diabetes, hypertension, or glomerular diseases
- Assess the severity and progression of chronic kidney disease (CKD)
- Guide therapy and monitor response to treatment
📊 Normal Range
PCR Value | Interpretation |
|---|---|
< 0.15 mg protein/mg creatinine (or < 150 mg/g) | Normal protein excretion |
0.15 – 0.5 mg/mg creatinine (or 150–500 mg/g) | Mild proteinuria |
> 0.5 mg/mg creatinine (or > 500 mg/g) | Significant proteinuria, likely nephropathy |
Note: Units vary by lab (mg/mg or mg/g). Confirm with lab reference.
📈 Interpretation of Results
PCR Level | Clinical Significance |
|---|---|
Normal | No significant proteinuria |
Mildly elevated | Early kidney damage or transient proteinuria |
Markedly elevated | Persistent proteinuria, suggests glomerular disease |
🧠 Associated Conditions
Organ/System | Conditions |
|---|---|
Kidneys | Diabetic nephropathy, glomerulonephritis, hypertension-related kidney disease |
Cardiovascular | Proteinuria as a marker of endothelial dysfunction |
Systemic Diseases | Lupus nephritis, vasculitis |
🔄 Related / Follow-Up Tests
- 24-hour urine protein estimation – confirmatory in some cases
- Serum creatinine and eGFR – evaluate kidney function
- Urinalysis and microscopy – detect red cells, casts
- Blood pressure monitoring
- Autoimmune serology if systemic disease suspected
