Understanding Protein in Urine: How the Test Works
Learn about proteinuria, its causes, symptoms, and how urine protein tests help diagnose kidney issues. Find out how the tests are conducted, preparation tips, and why accurate diagnosis is crucial for health management.
Proteins circulate in everyone's blood and are vital for maintaining overall health. They support muscle growth, strengthen bones, and help regulate body fluids. When kidney function declines, proteins can leak into the urine, leading to a condition called proteinuria. Individuals with diabetes, hypertension, or a family history of kidney disease are more susceptible. Symptoms such as foamy urine or abdominal swelling should prompt a medical check-up, which includes a urine protein test. This test assesses the amount of protein in urine, either from a single sample or over 24 hours.
An at-home or clinic-based one-time urine sample can identify abnormal protein levels. If needed, a 24-hour collection provides more detailed analysis. Preparation involves informing your doctor about medications and staying well-hydrated, as dehydration can distort results. To ensure accuracy, it's recommended to have tests done at multiple labs.
