Kidney & Renal Function Tests (KFT / RFT)

At Sakkthi Clinical Laboratory and Andrology Centre, we provide comprehensive Kidney Function Tests to evaluate how efficiently the kidneys are functioning. These tests analyze specific substances in blood and urine to help clinicians assess kidney health and detect possible abnormalities at an early stage.

What Do the Kidneys Do?

The kidneys are vital organs responsible for maintaining the body’s internal balance. Their main functions include:

  • Filtering waste products and toxins from the blood

  • Removing excess fluids through urine

  • Maintaining electrolyte balance in the body

  • Supporting blood pressure regulation

  • Helping maintain overall fluid balance

Laboratory testing helps determine whether the kidneys are performing these essential functions properly.

When Should Kidney Function Testing Be Considered?

Kidney function tests may be recommended if a person experiences:

  • Swelling in the legs, feet, or face

  • Changes in urination frequency or urine appearance

  • Persistent fatigue or weakness

  • High blood pressure

  • Diabetes or a family history of kidney disease

These tests are also commonly included as part of routine health check-ups or for monitoring existing medical conditions.

Common Kidney Function Tests

Kidney evaluation usually involves a combination of blood and urine tests, including:

  • Serum Creatinine: Measures a waste product filtered by the kidneys and helps evaluate kidney filtration efficiency.

  • Blood Urea Nitrogen (BUN): Assesses how effectively the kidneys remove waste from the bloodstream.

  • Electrolytes (Sodium, Potassium, Chloride): Evaluate the balance of important minerals regulated by the kidneys.

  • Estimated Glomerular Filtration Rate (eGFR): Provides an estimate of how well the kidneys are filtering blood.

  • Urine Analysis: Helps detect infections, protein leakage, or other abnormalities related to kidney health.


How Are These Tests Performed?

Kidney function testing typically involves:

  • Blood samples to measure waste products and electrolyte levels

  • Urine samples to assess kidney filtration and detect abnormalities


Do You Need Any Preparation?

Most kidney function tests do not require special preparation. However, your healthcare provider may give specific instructions depending on the tests being performed.


Why Kidney Function Testing Is Important

These tests help healthcare professionals to:

  • Evaluate overall kidney health

  • Detect early signs of kidney dysfunction

  • Monitor chronic conditions such as diabetes or hypertension

  • Assess response to treatment and disease progression
