A Biomarker for Early Detection of Renal Tubular Injury
This test measures the level of transferrin, a plasma protein, in urine. Elevated urinary transferrin indicates early kidney damage or glomerular dysfunction, often before albumin appears in urine. It’s used for monitoring kidney health, especially in high-risk patients like those with diabetes or hypertension.

How our test process works!
Overview:
-
Transferrin is a glycoprotein responsible for iron transport in the blood.
-
Normally, urine contains little to no transferrin. Its presence in urine can indicate glomerular damage or early kidney disease, especially before albumin appears.
Purpose / Indication:
-
Detect early kidney damage (especially in diabetic nephropathy).
-
Evaluate glomerular permeability.
-
Monitor kidney disease progression.
Risk Assesment:
-
Non-invasive; no significant risk.
-
Ensure proper urine collection to avoid contamination.
-
False positives possible with menstrual blood contamination, urinary tract infection, or vigorous exercise.
Normal Range:
-
Random urine: < 0.1 mg/dL
-
24-hour urine: < 0.1–0.3 mg/day (lab-specific reference may vary)
Interpretation:
-
Normal: Transferrin absent or very low.
-
Mild elevation: Early glomerular damage.
-
High levels: Significant kidney injury, glomerulonephritis, or proteinuria.
Sample Type:
-
Urine (usually a random or 24-hour collection).
