Protein (Urine)
- Sample Type
- Standard
- Fasting
- No
- Unit
- mg/dL
Measuring protein in the urine is a primary screen for kidney function. Normally, the glomerular basement membrane prevents large proteins like albumin from passing into the urine. The presence of protein (proteinuria) in a Complete Urine Examination is often the earliest sign of renal disease, including diabetic nephropathy, glomerulonephritis, or hypertensive kidney damage.

Why Context Matters
Transient proteinuria can occur due to fever, strenuous physical exercise, dehydration, or emotional stress (functional proteinuria), and does not always indicate permanent kidney damage.
Lab ranges are statistical averages, not biological laws. "Normal" for a 20-year-old male isn't normal for a 60-year-old female.
