protein in your urine causes
Your kidneys filter waste products from your blood while retaining what your body needs â 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: 1  Dehydration. 2  Emotional stress. 3  Exposure to extreme cold. 4  Fever. 5  Strenuous exercise.
Diseases and conditions that can cause persistently elevated levels of protein in urine, which might indicate kidney disease, include: Amyloidosis (buildup of abnormal proteins in your organs) Certain drugs, such as nonsteroidal anti-inflammatory drugs. Chronic kidney disease. Diabetes.
What is a Protein in Urine Test? A protein in urine test measures how much protein is in your urine. Proteins are substances that are essential for your body to function properly. Protein is normally found in the blood. If there is a problem with your kidneys, protein can leak into your urine. While a small amount is normal, a large amount of protein in urine may indicate kidney disease. Other names: urine protein, 24-hour urine protein; urine total protein; ratio; reagent strip urinalysis What is it used for? A protein in urine test is often part of a urinalysis, a test that measures different cells, chemicals, and substances in your urine.
