Protein in urine, or proteinuria, is a key health marker that can reveal kidney health and early signs of disease. This biomarker helps doctors detect and manage conditions such as diabetes, hypertension, and kidney disease.
Protein in urine occurs when excess protein is found in a urine sample. Normally, protein stays in the bloodstream, where it supports key functions like tissue repair, immune support, and fluid balance. Healthy kidneys filter waste but retain essential nutrients, such as protein.
When the kidneys are damaged, they may start leaking protein into the urine. This can be an early sign of kidney disease or other health conditions.
Doctors use protein in urine as a biomarker to monitor kidney health, track disease progression, and help diagnose conditions like high blood pressure, diabetes, and certain cancers.

A protein in urine test, often part of a routine urinalysis, can help detect early signs of kidney disease or other health issues. This test may be recommended in various situations, such as:
Testing for protein in urine is typically done through a simple urine sample. The most common method is the dipstick test, which uses a small strip treated with chemicals that change color in the presence of protein.
For more accurate results, doctors may request a 24-hour urine collection, where all urine is collected over a day to measure protein levels consistently.
Urine protein tests are often part of broader tests, such as urinalysis or kidney function panels. In cases where more detail is needed, doctors may order additional tests like a serum albumin test to check protein levels in the blood.
Preparation for the Test:
In healthy adults, protein levels in urine are typically 0-14 mg/dL. Levels above this range may indicate kidney problems or other health issues.
Note: The units of measurement and the normal ranges can differ depending on the laboratory and the specific methods used.

High levels of protein in urine can be a sign of various health conditions. Persistent proteinuria may indicate issues like:
If you have high protein levels in your urine, lifestyle changes and medical support can help manage it. Consider the following:
Low protein levels in urine are generally considered normal. However, low levels in the bloodstream alongside low levels in urine can sometimes indicate other health conditions.
To maintain healthy protein levels, consider these steps:
If you have abnormal protein levels in your urine, consulting a nephrologist (kidney specialist) is often recommended. A nephrologist can help determine the underlying cause of proteinuria, develop a treatment plan, and monitor kidney health over time.
For those with related health conditions like diabetes or hypertension, coordinated care between specialists can be beneficial for comprehensive management.
During pregnancy, some protein in the urine is common, but levels are typically below 300 mg/day. Higher levels can indicate conditions like preeclampsia, so regular monitoring is crucial.
Yes, intense physical activity can temporarily raise protein levels in urine, a condition known as exercise-induced proteinuria. Levels usually return to normal with rest.
Dehydration can cause a temporary increase in protein concentration in urine. Staying hydrated is essential for accurate test results and kidney health.
High intake of protein-rich foods can sometimes elevate protein levels in urine temporarily. Doctors often advise moderating protein intake before a urine protein test.
