Urine protein - 24 hour

The normal value is less than 150 milligrams per day, or less than 10 milligrams per deciliter of urine.

Note: Normal value ranges may vary slightly among different laboratories. Talk to your doctor about the meaning of your specific test results.

Increased levels of urinary protein may be due to:

• Glomerulonephritis
• Nephrotic syndrome
• Microalbuminuria or other early signs of diabetic nephropathy
• Renal tubular diseases including pyelonephritis, Fanconi syndrome, cystinosis, and Wilson's disease
• Multiple myeloma
• Waldenstrom's macroglobulinemia
• Some lymphomas

Healthy people may have higher than normal urine protein levels after strenuous exercise or with dehydration. Some foods may affect urine protein levels.
