Microalbuminuria (MAU): What It Detects, Normal Range

Overview

The Microalbuminuria (MAU), Spot Urine test measures small amounts of albumin, a protein that is normally retained in the bloodstream by healthy kidneys. When the kidneys begin to lose their filtering ability, small amounts of albumin can leak into the urine—a condition known as microalbuminuria. This test is one of the earliest indicators of kidney damage and is commonly recommended for individuals with diabetes, hypertension (high blood pressure), or other conditions that increase the risk of chronic kidney disease (CKD). Early detection allows timely intervention to help protect kidney function.

What It Measures

Why Take This Test?

• To detect early kidney damage before symptoms develop. To monitor kidney health in people with diabetes or high blood pressure. To assess the risk of chronic kidney disease (CKD). To evaluate protein leakage in the urine. To monitor the effectiveness of treatment for kidney disease. To support routine kidney health screening in high-risk individuals.

How to Prepare

Inform your healthcare provider about any medications or existing medical conditions. If you have symptoms of a urinary tract infection or are menstruating
