Leakage of Protein in the Urine

Your kidneys filter waste products from your blood while keeping what your body needs — including proteins. However, some diseases and conditions allow proteins to pass through the filters of your kidneys, causing protein in urine.

Conditions that can cause a temporary rise in the levels of protein in urine, but don't necessarily indicate kidney damage, include:

• Dehydration
• Exposure to Extreme Cold
• Fever
• Strenuous Exercise

Tests to identify protein in urine are critical for diagnosing and screening for diseases of the kidneys or other conditions affecting kidney function. These tests are also used to monitor disease progression and treatment effect.
