The kidneys are two bean-shaped organs that are responsible for filtering out extra waste and water from the blood and making urine. Any kidney related disease may cause electrolytes and waste build-up in the body. While in earlier stages of chronic kidney disease (CKD), there are very few symptoms until the condition is advanced.


What is kidney function test (KFT)?


It is a set of blood and urine tests that give detailed insights into the kidney health. These tests find out how successfully the kidneys remove waste from the body. It might include a blood test, a 24-hour urine sample, or a combination of the two. KFT test is part of a routine check-up to diagnose any kidney disease and to find out how the treatment for the kidney disease is working.


KFT test price will vary depending on the location of the facility and the city where the pathology service is located.


Why are these tests prescribed?


This test is recommended as part of a routine check-up to diagnose any disease affecting the kidneys and to identify individuals who are at risk of any renal disease. People with diabetes are at higher risk of CKD – a condition in which the kidneys become damaged over a period of time, resulting in compromised blood filtration. Significantly, CKD frequently remains asymptomatic until considerable kidney impairment has occurred.

Symptoms


With the rapid progression of kidney disease, the signs and symptoms of CKD emerge gradually. Reduced kidney function can lead to the accumulation of fluid, waste products, and electrolyte imbalances within the body. The extent of kidney function loss determines the range of symptoms experienced:


  • Altered urination patterns
  • Persistent fatigue and weakness
  • Nausea
  • Vomiting
  • Reduced appetite
  • Sleep disturbances
  • Impaired cognitive acuity
  • Muscle cramps
  • Swelling in the feet and ankles
  • Dry and pruritic skin
  • Hypertension
  • Breathlessness


The indications and manifestations of kidney disease are often vague and not distinctive.

What are the different types of KFT?


The tests consist of a panel of blood tests and urine tests to provide an overview of kidney health. The main components of a KFT include:


Blood Urea Nitrogen (BUN): Urea is the waste product produced by the liver during the break down of proteins. It is then filtered out of the blood by the kidneys and leaves the body through urine. The level of Urea nitrogen in the blood is a marker of how well the kidneys are working. Elevated levels of urea nitrogen show that kidneys aren’t working properly. This means there is a condition that’s affecting the kidney’s health.


Serum Creatinine: Healthy kidneys filter creatinine from the blood. Creatinine is a byproduct formed during muscle metabolism. Higher levels of serum creatinine may indicate an issue with the kidneys.


Glomerular Filtration Rate (GFR): This test measures how much blood passes through the glomeruli each minute. Glomeruli are the kidney’s tiny filters that clear waste from the blood.


Creatinine Clearance: It evaluates how effectively the kidneys are clearing creatinine from the blood. It calculates the amount of creatinine in a 24-hour urine sample, along with a serum creatinine level.


Serum Electrolytes: The test measures the body’s main electrolytes – sodium, potassium and calcium. Any imbalance in the levels of these electrolytes can indicate kidney dysfunction.


Urine Analysis: This test checks the components of urine in a sample. It includes assessing the presence of protein, blood, glucose, and other substances.
