Urine Microalbumin & ACR (Albumin-to-Creatinine Ratio)

Urine Microalbumin is a test that measures the amount of albumin, a type of protein, in the urine. Under normal circumstances, the kidneys filter waste products and retain essential proteins like albumin in the bloodstream. However, when the kidneys are damaged, small amounts of albumin can leak into the urine, a condition known as microalbuminuria.

ACR (Albumin-to-Creatinine Ratio) is a more accurate test that compares the amount of albumin with the amount of creatinine in the urine. Creatinine is a waste product produced by the muscles and excreted by the kidneys at a relatively steady rate. By calculating the ratio, ACR accounts for urine concentration variations, providing a reliable indicator of kidney function.

Why Are These Tests Important?

  • Early Detection of Kidney Damage: These tests help detect kidney damage at an early stage, particularly in people with diabetes, hypertension, or cardiovascular risks.
  • Monitoring Chronic Conditions: For patients with diabetes or high blood pressure, regular testing helps assess the progression of kidney disease and the effectiveness of treatments.
  • Risk of Cardiovascular Disease: Elevated microalbumin levels may indicate an increased risk of heart disease or stroke.

Test Interpretation:

  • Normal: ACR < 30 mg/g
  • Microalbuminuria: ACR between 30–300 mg/g (early kidney damage)
  • Macroalbuminuria: ACR > 300 mg/g (significant kidney damage)

Who Should Get Tested?

  • Patients with Type 1 or Type 2 diabetes
  • Individuals with high blood pressure
  • People with a family history of kidney disease
  • Those at risk of cardiovascular disease

The Urine Microalbumin and ACR test is a simple, non-invasive, and highly effective way to detect early kidney damage and prevent further complications with timely intervention. Regular monitoring is key to maintaining kidney health and overall well-being.
