Kidney Function Test (KFT)

A kidney function test is performed to determine the overall health of the kidneys and their functioning. Depending on the kidney function test being performed, a blood sample or urine sample or both will be collected for testing. A kidney function test is generally prescribed for the diagnosis of certain symptoms that indicate kidney disease, to monitor the efficacy of a treatment plan, to monitor side-effects of certain medication, or if a person is suffering from a health condition that may affect the kidneys. Regular testing can help with the early detection of kidney diseases and is crucial for people with high risk factors of developing kidney diseases.

The Kidney Function Test (KFT) is a test panel that is performed to determine kidney health. It can include several specific tests like:

• Blood Urea Nitrogen (BUN) Test: Measures nitrogen level in the blood.
• Serum Creatinine Test: Measures level of creatinine in the blood.
• Estimated Glomerular Filtration Rate (eGFR): Calculates how efficiently the kidneys are removing waste and excess fluids from the body.
• Microalbuminuria Urine Test: Detects the presence of the albumin protein.
• Urinalysis: Helps in the detection of a variety of kidney disorders.

In many cases, abnormal results of the KFT test may require one to undergo further testing, like imaging tests or a biopsy, for a more comprehensive overview of the condition of their kidneys for a proper diagnosis.

It depends on why a person is undergoing the test and the condition or disease that may be affecting their kidneys. For example, while the creatinine test assesses how efficiently the kidneys are removing waste from the body, a urinalysis helps detect various urinary tract or kidney disorders. The price of a KFT test panel is inclusive of several tests that are performed to measure the levels of different components like calcium, uric acid, bicarbonate, creatinine, etc. The results of the KFT can be used to determine if further tests are required.

When one undergoes a blood test for kidney function, one may be asked to observe an overnight fast before sample collection. Furthermore, the consulting doctor will be able to determine if any special preparation is required before the blood test for kidney function, based on the patient’s health condition, the medication (if any) they are on, etc.

Common early symptoms of kidney problems include:

• Swelling over legs, feet, or ankles
• Puffiness or swelling around the eyes
• Weakness
• Loss of appetite
• Vomiting or nausea during the early hours of the day
• Anaemia
• Unexplained increase or decrease in the frequency of urination
• Bloody or foamy urine
• Dryness and itchiness of the skin
• Pain in the back or pain in the abdomen
• Raised blood pressure

For a definitive diagnosis, one must undergo a blood test for kidney function. It is also a good idea to make the blood test for kidney function a part of regular full body health checks, to facilitate early detection of kidney disorders or conditions, especially if any risk factors are present.

Yes. The kidney profile test panel is specific for the diagnosis and management of kidney-related problems and conditions. However, at times, a doctor may also prescribe a kidney profile test to a person suffering from a health condition that may affect their kidneys. In such cases, the kidney profile test is performed to monitor kidney health.

Symptoms caused by high creatinine levels may include:

• Irregular heart rate
• Nausea
• Fatigue
• Fluid retention in the lower body
• Loss of appetite
• Increased or decreased frequency of urination

The creatinine test is generally a part of the lab test panel for kidney function.

Failing kidney functions lead to a build-up of harmful wastes and excess fluids in the body, which can cause the urine to turn bloody or darker than usual, with tinges of brown, red, or purple. If one notices a change in the colour of their urine, they might need to book a kidney function test online and should consult with their doctor immediately.
