### What is a Microalbumin Urine Test? A microalbumin urine test checks for small amounts of a protein called albumin in your urine. Normally, your kidneys filter waste from your blood and keep the good stuff, like proteins, in your body. But if your kidneys are damaged, they may start to leak albumin into your urine. This test can detect kidney problems early on, even before you have any symptoms. ### Why is it Important for People with Diabetes? Diabetes is the leading cause of kidney failure. High blood sugar levels can damage the small blood vessels in your kidneys, making it harder for them to filter your blood. Over time, this can lead to kidney disease. A microalbumin urine test can help catch kidney problems early, allowing you to take steps to protect your kidneys and prevent more serious issues. ### How Does the Test Work? To check for albumin, you'll need to provide a urine sample. There are a few different ways to do this: - **Random Test:** A single urine sample is taken at any time. - **Timed Test:** Urine is collected over a specific period, like 4 hours or overnight. - **24-Hour Test:** All urine is collected over a 24-hour period. ### Understanding the Results - **Random Test:** - Normal: Less than 30 micrograms (mcg) per milligram (mg) of creatinine - Microalbuminuria: 30-300 mcg/mg - Clinical albuminuria: More than 300 mcg/mg - **Timed Test:** - Normal: Less than 20 mcg/minute - Microalbuminuria: 20-200 mcg/minute - Clinical albuminuria: More than 200 mcg/minute - **24-Hour Test:** - Normal: Less than 30 mg - Microalbuminuria: 30-300 mg - Clinical albuminuria: More than 300 mg If your results show a high level of albumin, your doctor will likely repeat the test a few times over the next 3 to 6 months. If two out of three tests are high, it usually means you have early kidney disease. Your doctor will help you understand what the results mean and what steps you can take to protect your kidneys.
