Kidney Function

What is Microalbumin? Your Complete Guide

Q: What is the normal range for Microalbumin?

The typical normal range for Microalbumin is 0–30 mg/L.

Q: What causes high Microalbumin?

Diabetic nephropathy (most common in India). Hypertension damaging kidney filters. Early glomerular disease.

Q: What causes low Microalbumin?

Normal finding — indicates healthy kidneys. Very dilute urine sample (not truly low).

Q: How can I check my Microalbumin levels?

You can check your Microalbumin levels with a routine blood test. Upload your lab report to ScanHealth for an instant, plain-language explanation.

Microalbumin measures tiny amounts of albumin protein leaking into your urine. Healthy kidneys keep albumin in the blood — even small leaks indicate early kidney damage, especially from diabetes or high blood pressure.

💡Simply Explained

Microalbumin is like a smoke detector for your kidneys. Just as a smoke detector warns you before a fire gets big, microalbumin catches kidney damage very early — when there's just a tiny leak, long before your kidneys actually start failing.

⬆️What High Microalbumin Means

Possible Causes

Diabetic nephropathy (most common in India)
Hypertension damaging kidney filters
Early glomerular disease
Lupus or other autoimmune kidney disease
Heart failure

Foods That Can Help

Control blood sugar aggressively (HbA1c <7%)
Start or adjust ACE inhibitor/ARB medication (kidney-protective)
Monitor blood pressure — target <130/80
Reduce salt intake significantly
Retest in 3 months to confirm

⬇️What Low Microalbumin Means

Possible Causes

Normal finding — indicates healthy kidneys
Very dilute urine sample (not truly low)

Foods That Can Help

No specific foods — this is a normal result
Maintain a kidney-friendly diet as prevention

🏃Lifestyle Actions

If Your Microalbumin Is High

Get HbA1c and blood pressure checked immediately
Start or optimize ACE inhibitor/ARB (doctor to prescribe)
Reduce salt: limit papad, pickle, namkeen, processed foods
Control blood sugar with diet, exercise, and medication
Retest every 3-6 months to track progression

If Your Microalbumin Is Low

No action needed — kidneys are healthy
Continue regular annual screening if diabetic or hypertensive

🩺When to See a Doctor

High Microalbumin

Microalbumin above 300 mg/L (macroalbuminuria) indicates significant kidney damage — see a nephrologist within 1-2 weeks. Values of 30-300 with uncontrolled diabetes or hypertension need attention within 2-4 weeks.

Low Microalbumin

Normal microalbumin requires no urgent action. Continue annual screening if you have diabetes or hypertension.

🎯Did You Know?

Your kidneys filter about 180 liters of blood every day — that's enough to fill a bathtub twice! Despite all that filtering, healthy kidneys are so precise that they let less than 30 milligrams of albumin slip through.
