Kidney Function Test (KFT)

What Does the Kidney Function Test (KFT) Measure?

The main purpose of a KFT is to see if your kidneys are effectively filtering waste products from the blood and maintaining your body's balance of electrolytes and fluids:

• Serum Creatinine: A waste product from normal muscle wear and tear that healthy kidneys filter out.
• Blood Urea Nitrogen (BUN): A waste product formed when your body breaks down protein.
• Estimated Glomerular Filtration Rate (eGFR): Estimates how much blood your kidneys filter per minute.
• Uric Acid: A waste product from the breakdown of purines that the kidneys help excrete.
• Electrolytes: Includes sodium, potassium, and chloride, which help regulate fluid balance, nerve function, and muscle contraction.
• Proteins: Including albumin and globulin levels that indicate kidney and liver health.
• Urine Analysis: Checks for protein, blood cells, and other substances in urine.

Kidney Function Test (KFT): Who Needs It and Why It's Done

What Symptoms May Call for a Kidney Function Test (KFT)?

Your doctor may recommend a KFT if you experience symptoms that suggest potential kidney problems:

• Swelling in hands, ankles, feet, or around the eyes
• Changes in urination patterns, especially at night
• Foamy, bubbly, or bloody urine
• High blood pressure
• Persistent fatigue and weakness
• Loss of appetite, nausea, or vomiting
• Dry, itchy skin
• Muscle cramps or twitching

Who Should Get a Kidney Function Test (KFT)?

Several groups of people benefit from regular kidney function monitoring:

• People with diabetes or high blood pressure.
• Individuals with a family history of kidney disease.
• Older adults whose kidney function naturally declines with age.
• Patients on certain medications that may affect kidney function over time.
• People with heart disease, obesity, or autoimmune conditions like lupus.
• Anyone seeking a comprehensive health screening, as kidney disease often shows no early symptoms.

Why Is a Kidney Function Test (KFT) Done?

A KFT is done to diagnose kidney disease at an early stage, monitor the progression of existing conditions, and make timely treatment decisions to prevent irreversible kidney failure.

Importance of a Kidney Function Test (KFT)

The kidney function test is clinically vital because chronic kidney disease often develops silently without noticeable symptoms until significant, irreversible damage occurs. Early detection through regular KFT screening allows doctors to implement protective treatments, recommend lifestyle modifications, and monitor disease progression.

By measuring key parameters, like eGFR and protein levels, the test helps doctors stage kidney disease accurately, guide treatment decisions, and prevent complications. This proactive approach can significantly slow disease progression and improve your long-term health outcomes.
