The Kidney Function Test (KFT) is a group of tests designed to assess how well your kidneys are functioning. These tests evaluate the kidneys’ ability to filter waste products, maintain the balance of electrolytes, and regulate other important body functions.
Components of a KFT:
- Blood Urea Nitrogen (BUN):
Measures the amount of urea nitrogen in your blood. High levels may indicate impaired kidney function. - Serum Creatinine:
Assesses the level of creatinine in your blood. Elevated levels are a sign of reduced kidney function. - Estimated Glomerular Filtration Rate (eGFR):
Estimates how efficiently the kidneys are filtering blood. It’s calculated using serum creatinine, age, gender, and other factors. - Uric Acid Levels:
Helps in diagnosing gout or kidney-related conditions. - Electrolyte Levels:
Tests sodium, potassium, and chloride, which are crucial for maintaining body balance and kidney health. - Blood Urea Levels:
Measures the urea concentration in the blood, an indirect indicator of kidney efficiency. - Urine Tests (optional in KFT):
- Urine Creatinine: Assesses creatinine excretion.
- Urinalysis: Checks for protein, blood, or other abnormalities in urine.
Why is a KFT Test Important?
- Diagnoses Kidney Diseases: Helps detect early-stage kidney diseases.
- Monitors Chronic Conditions: Useful in managing diabetes or high blood pressure.
- Guides Treatment: Helps doctors adjust medications or recommend lifestyle changes.
- Post-Treatment Evaluation: Assesses recovery after a kidney-related illness or surgery.
If you suspect any kidney issues or have chronic conditions like diabetes or hypertension, your doctor might recommend a KFT to ensure your kidneys are functioning properly.
