Kidney

Microalbumin (Urine)

Microalbumin testing is especially relevant for women during pregnancy, when increased kidney workload can reveal underlying vulnerabilities. Women with gestational diabetes or pre-eclampsia may benefit from regular monitoring to protect both maternal and foetal health.

Reference ranges may vary between laboratories. When you order a test, a BIG-registered doctor assesses your personal results in context. For treatment decisions, discuss your results with your GP.

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

Normal microalbumin levels generally indicate healthy kidney filtration function.

High Levels

Foamy or frothy urine
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

Female

If Low

Normal microalbumin indicates healthy kidney function. Maintain blood pressure and blood sugar control.

If High

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.

Frequently Asked Questions

What is the difference between microalbumin and proteinuria?
Microalbuminuria refers to the presence of small amounts of albumin in urine (30-300 mg/day) and is considered an early warning sign. Proteinuria involves larger amounts of protein and typically indicates more advanced kidney damage. Microalbumin testing is more sensitive for early detection.
Can microalbuminuria be reversed?
In many cases, microalbuminuria can be reduced or reversed with appropriate management, particularly through blood pressure control, blood sugar management, and medications such as ACE inhibitors. Early detection and intervention offer the best outcomes.
Do I need to fast before a microalbumin test?
No, fasting is generally not required for a microalbumin urine test. However, strenuous exercise, urinary tract infections, and fever can temporarily affect results. Follow any specific instructions provided by your healthcare provider.
