If a urine test reveals protein in your urine, ask your doctor whether you need further testing. Because protein in urine can be temporary, your doctor might recommend a repeat test first thing in the morning or a few days later.
Your doctor might order other tests, such as a 24-hour urine collection, to determine if there is a cause for concern.
If you have diabetes, your doctor may check for small amounts of protein in urine — also known as microalbuminuria (my-kroh-al-byoo-min-U-ree-uh) — once or twice each year. Newly developing or increasing amounts of protein in your urine may be the earliest sign of diabetic kidney damage.
