Kidney Function Test is used to assess how well your kidneys are working by measuring the levels of certain waste products and electrolytes in your blood. The kidneys filter waste from your blood, regulate fluid balance and help control blood pressure.
Key tests included in kidney function:
- Serum creatinine: Measures the level of creatinine, a waste product produced by muscle metabolism. Elevated creatinine levels can indicate reduced kidney function.
- Blood urea nitrogen (BUN): Measures the amount of urea nitrogen in your blood. Urea is produced when the body breaks down protein, and high levels can signal kidney dysfunction.
- Glomerular filtration rate (GFR): Estimates how well your kidneys are filtering blood. A low GFR may indicate impaired kidney function or chronic kidney disease (CKD).
- Electrolytes: Tests like sodium and potassium help assess your kidneys’ ability to regulate electrolyte balance and fluid levels.
Why it’s important:
- Assess kidney health: A kidney function test helps diagnose conditions like chronic kidney disease (CKD), acute kidney injury, or kidney damage caused by conditions like diabetes or high blood pressure.
- Monitor existing conditions: If you already have kidney disease or are at risk (e.g., due to diabetes or hypertension), regular kidney function tests are important to track the progression of the disease.
- Prevent complications: Early detection of kidney problems can lead to earlier treatment, reducing the risk of serious complications like kidney failure.
