Understanding Kidney Function Testing
Kidney function testing is a diagnostic procedure used to evaluate how well the kidneys are working. These tests help identify early signs of kidney disease, monitor existing kidney conditions, and guide treatment plans for related health issues.
What Is Kidney Function Testing?
Kidney function testing involves blood and urine tests that measure waste products, electrolytes, and fluid balance in the body. Common tests include:
Serum Creatinine – Measures creatinine levels in the blood
eGFR (Estimated Glomerular Filtration Rate) – Assesses kidney filtration efficiency
Urea (BUN) – Evaluates protein breakdown waste
Urine Albumin-to-Creatinine Ratio (ACR) – Detects early kidney damage
Urinalysis – Checks for abnormalities like protein or blood in the urine
These tests are often part of routine health checks or ordered when kidney-related symptoms are present.
