Kidney function tests, also known as KFTs, are a group of tests that are used to measure how well your kidneys are working. It includes measuring the levels of certain substances in your blood and urine. Kidney function tests can help determine the cause of kidney problems and may also be used to monitor people with chronic kidney disease. This blog post will discuss kidney function tests’ price range, purpose, and results.
Let’s get started.
What is KFT?
Kidney function tests (KFTs) are a group of blood and urine tests used to evaluate how well the kidneys are functioning. The tests measure levels of certain substances in the blood, such as creatinine, urea, and electrolytes. A KFT can also detect changes in the structure and function of the kidney.
There are many different types of KFTs, but they all have one common goal: to assess kidney function. Some common KFTs include estimated glomerular filtration rate (eGFR), serum creatinine, urinary albumin excretion, and renal ultrasound.
The Significance of Kidney Function Test
A kidney function test is done to find problems early on before they become more serious. Kidney function tests also help monitor kidney disease and see how well treatments work.
On an estimate, 18 people out of 100 have some degree of chronic kidney disease. Excessive salt intake, being overweight, diabetes, and high blood pressure are some factors leading to chronic kidney disease.
A kidney function test is done to:
- Check for early signs of kidney disease
- See how well the kidneys are working
- Monitor kidney disease
- Evaluate the effectiveness of treatments for Kidney disease
KFT Test For Particular Kidney Issues
If you suspect kidney abnormalities, you could do a kidney function test. The following signs and symptoms are typical of renal diseases:
- High blood pressure
- Blood in urine
- Swollen Hand or Foot
- Pain during urination
- Fatigue or weakness
- Frequent stomach upset
- Frequent urinating, particularly at night
- Chest pain, Persistent itching, & breathing difficulty
Tests Included In Kidney Function Test
The most critical tests included in kidney function test include:
It is produced by muscle metabolism and enters the bloodstream. Kidneys filter creatinine and remove it from the blood into the urine. If the kidneys are not functioning properly, the creatinine level in the blood will rise.
Uric acid is created due to the organic molecule (purines) being chemically broken down. The kidney must filter and eliminate this waste material through the urine. As a result, high or low uric acid levels might mean renal injury.
Blood Urea Nitrogen (BUN)
The breakdown of proteins in our body results in the production of urea nitrogen. It is a harmful substance that the kidneys eliminate through urine. If the kidneys are not functioning properly, BUN can accumulate in the blood.
Estimated Glomerular Filtration Rate (EGFR)
The GFR calculates the kidneys’ ability to filter waste. A patient’s normal GFR may not always correspond to their normal serum creatinine. To evaluate renal function, it is preferable to calculate glomerular filtration rate (eGFR), the “gold standard” measurement.
Extra Optional Parameters
Some laboratories may include mineral analyses including sodium, calcium, & chloride in kidney function tests. It is more typical to assess these values as part of an additional electrolyte profile test.
KFT Test Cost
Based on the facility and region, the price of Kidney function tests vary. Kidney function tests typically have various parameters, contributing to their variable cost. But broadly speaking, the cost varies from Rs 585 – Rs 1000.
Nevertheless, a doctor often orders several tests focused on various body parts. The cost of most of these tests might be reduced if they are included in certain health plans.
Kidney Function Test Results
Abnormal kidney function test findings indicate kidney disease. The KFT test cannot pinpoint the root cause of the issue. Additionally, an underlying condition may lead to an abnormal report.
Nonetheless, some kidney issues are easily cured, and some may be avoided with lifestyle changes. A few simple lifestyle adjustments, such as drinking more water, cutting back on salt, abstaining from drugs and alcohol, and being active, can have a good effect on the kidneys.
The Bottom Line
Kidney function tests measure the levels of specific substances in your blood, such as creatinine and urea nitrogen. These tests can also estimate how well your kidneys filter waste from your blood. The price of a kidney function test varies based on location but typically falls between Rs 585 – Rs 1000. The cost may be higher if you have multiple tests done or if you need to see a specialist.
