Doctor's Assessment Included
Every result includes a professional assessment from a BIG-registered doctor. For treatment decisions, discuss your results with your GP.
Microalbumin (Urine)
Microalbumin testing helps athletes understand kidney stress related to intense training. Exercise-induced proteinuria can temporarily elevate urine albumin levels, so understanding your baseline is important for distinguishing normal training responses from potential kidney concerns.
What It Measures
This test measures the amount of albumin present in your urine. Albumin is a protein normally found in the blood that plays a key role in maintaining fluid balance and transporting nutrients.
When the tiny blood vessels in the kidneys (glomeruli) are damaged, they begin to leak small amounts of albumin into the urine. This leakage, called microalbuminuria, is one of the earliest detectable signs of kidney impairment.
Why It Matters
Microalbumin testing is particularly important for individuals with diabetes or hypertension, as these conditions are leading causes of kidney damage. Detecting microalbuminuria early allows for timely intervention that may slow or prevent further kidney decline.
Without early detection, kidney damage can progress silently over years, potentially leading to chronic kidney disease. Regular monitoring provides the opportunity to adjust treatment and lifestyle factors before significant damage occurs.
When to Test
Testing is recommended annually for individuals with type 1 or type 2 diabetes, as well as those with high blood pressure. It may also be advised when there is a family history of kidney disease or other risk factors.
Your healthcare provider may recommend more frequent testing if previous results showed elevated levels, or if you are managing conditions that can affect kidney function.
Symptoms
Low Levels
High Levels
Swelling in the ankles, feet, or hands
High blood pressure that is difficult to control
Increased urination, particularly at night
Fatigue and general malaise
Recommendations
Male
Normal microalbumin indicates healthy kidney function. Maintain blood pressure and blood sugar control.
Elevated microalbumin is an early sign of kidney damage. Consider blood pressure management and diabetes control.
Female
Normal microalbumin indicates healthy kidney function. Maintain blood pressure and blood sugar control.
Elevated microalbumin is an early sign of kidney damage. Consider blood pressure management and diabetes control.
Lifestyle Tips
Maintain stable blood sugar levels if you have diabetes, as good glycaemic control is one of the most effective ways to protect kidney function. Keep blood pressure within a healthy range through dietary changes, regular exercise, and medication if prescribed.
Reduce sodium intake, stay well hydrated, and avoid excessive use of non-steroidal anti-inflammatory drugs (NSAIDs), which can affect kidney function. Regular follow-up with your healthcare provider is essential for ongoing monitoring.
