Normal urine microalbumin is an albumin-to-creatinine ratio (ACR) below 30 mg/g (<3 mg/mmol). An ACR of 30–300 mg/g (3–30 mg/mmol) indicates microalbuminuria; >300 mg/g indicates overt proteinuria. By 24-hour collection, normal albumin excretion is under 30 mg/day. Results can vary by lab and clinical context, so discuss abnormal values with your clinician.

Albumin in the urine (albuminuria) can be an early sign of kidney damage. Small, transient amounts may occur with exercise, fever, or dehydration, but persistent or higher levels are serious—linked to chronic kidney disease and greater cardiovascular risk. Repeat testing (albumin-to-creatinine ratio) and medical evaluation are needed. Treatment focuses on controlling blood pressure, blood sugar and using medications to protect kidneys.

A high urine microalbumin creatinine ratio indicates abnormal albumin loss in the urine, an early sign of kidney damage (microalbuminuria). It raises the risk of progressive chronic kidney disease and cardiovascular disease, especially with diabetes or hypertension. Next steps include repeat testing, kidney function checks, tighter blood-pressure and glucose control, lifestyle changes, and often medications such as ACE inhibitors or ARBs to slow progression.

Normally urine contains very little albumin—less than about 30 mg over 24 hours. A normal urine albumin-to-creatinine ratio (ACR) is under 30 mg/g (under 3 mg/mmol). Persistent albumin excretion of 30–300 mg/day indicates microalbuminuria; over 300 mg/day indicates overt proteinuria and should prompt further kidney evaluation. Small transient increases can occur after exercise or infection.

Improve blood‑pressure and blood‑glucose control (ACE inhibitor or ARB when indicated), reduce dietary salt, lose excess weight, exercise regularly, and stop smoking. Treat high cholesterol and avoid nephrotoxins (NSAIDs, dehydration). Moderate protein and alcohol intake. Get routine urine albumin‑to‑creatinine checks and follow your clinician’s plan to adjust medications and lifestyle to lower microalbuminuria.

Elevated serum albumin (hyperalbuminemia) is uncommon and most often reflects hemoconcentration from dehydration. Less common causes include high dietary protein, corticosteroid use, severe vomiting/diarrhea, or lab artifact. It usually signals fluid deficit or an underlying illness rather than primary disease. Treatment targets rehydration and addressing the root cause; persistent or unexplained elevation merits medical review and repeat testing.
