The Albumin-to-Creatinine Ratio (ACR) test is a crucial diagnostic tool for evaluating kidney function. It helps detect early signs of kidney damage by measuring the ratio of albumin to creatinine in the urine. Here's a closer look at its importance:
- What the ACR Measures:
- Albumin: A protein normally found in the blood. When the kidneys are functioning properly, they prevent large amounts of albumin from passing into the urine.
- Creatinine: A waste product from muscle metabolism, filtered out by the kidneys. The ratio between albumin and creatinine helps determine if the kidneys are allowing too much albumin to pass into the urine.
- Role in Assessing Kidney Function:
- ACR is primarily used to detect kidney damage, often before other symptoms appear. Elevated albumin levels in the urine indicate that the kidneys are not filtering properly, which could be a sign of chronic kidney disease (CKD).
- Early detection: This test is especially important for those with risk factors like diabetes or hypertension, where kidney damage may develop without symptoms.
- Interpreting Results:
- Normal ACR levels: Less than 30 mg/g.
- Moderately increased: 30-300 mg/g, indicating early kidney damage.
- Severely increased: Over 300 mg/g, suggesting significant kidney damage.
Treatment depends on the underlying cause but may involve managing blood pressure, controlling blood sugar levels, or medications to protect kidney function.
c) Recommended Tests:
- Creatinine Test
Creatinine is a key marker in assessing kidney function. Measuring blood creatinine levels helps further evaluate how well the kidneys are filtering waste.
Creatinine Test - Estimated Glomerular Filtration Rate (eGFR)
This test measures how well your kidneys are filtering, complementing the ACR in diagnosing kidney disease.
