What are other reasons for a high microalbumin result?

A high albumin level in your urine (called microalbuminuria) may indicate early kidney disease. However, several factors can cause elevated proteins in your urine, such as blood in your urine (called hematuria), certain medications, fever, recent heavy exercise, urinary tract infection, and other kidney diseases. The microalbumin test can’t diagnose kidney disease or other conditions, so it’s important to follow up with a healthcare provider to talk about your results. Your healthcare provider can help you make a plan to best manage your health.
