LFT and KFT (Liver Function Test & Kidney Function Test)









The LFT and KFT (Liver Function Test & Kidney Function Test) comprises two profiles: a liver function test and a kidney function test with electrolytes, which help evaluate liver and kidney function and identify disorders associated with these organs. In addition, this package also assesses the pH and water balance in the body.












Understanding LFT and KFT (Liver Function Test & Kidney Function Test)
The liver is the largest organ in our body and performs various vital functions, including:
- Metabolizing nutrients (like fats, proteins, carbohydrates) and certain medications
- Detoxifying the blood by converting toxins into waste products
On the other hand, the kidneys play a vital role in:
- Filtering waste, toxins, and excess water from the body
- Regulating water, electrolytes (like sodium, potassium, and calcium), and pH levels
- Controlling blood pressure
- Producing hormones involved in red blood cell formation
- Supporting bone health
The LFT and KFT (Liver Function Test & Kidney Function Test) package plays a crucial role in screening for and supporting the diagnosis of liver conditions, such as fatty liver disease, cirrhosis, jaundice, and hepatitis, and in evaluating kidney conditions, such as kidney stones, urinary tract infections, and gout. This package also supports clinicians in clinical decision-making. It can also effectively monitor ongoing treatment for existing liver or kidney issues.
No special preparation is required for this package. Eat and drink as per the daily routine. However, inform the doctor of all medications being taken, as some may affect the test results.
Test result ranges are approximate and may vary slightly across laboratories, depending on methodology and laboratory guidelines. Talk to the doctor about specific test results. Narrate the complete medical history to help them correlate your clinical and laboratory findings. The test results will help the doctor determine the medical condition and formulate a treatment plan.
Health Tips for Kidney & Liver Wellness:
🥤Hydration: Drink enough water throughout the day. It supports kidney filtration and liver detoxification, helping your body flush out toxins effectively.
🥗 Eat (Balanced Diet): Choose a diet rich in fruits, vegetables, whole grains, and lean proteins. Avoid excess salt, sugar, unhealthy fats, and processed foods to reduce strain on both kidneys and the liver.
🏃♀️ Activity (Exercise): Stay physically active with regular exercise like walking or cycling. This helps manage weight and blood pressure and prevents fatty liver and kidney strain.
🧘 Lifestyle (Stress Management): Practice yoga, meditation, or breathing techniques. Managing stress reduces hormonal imbalances that can impact kidney and liver function.
👩⚕️ Talk to Your Doctor (Consultation): Don’t self-medicate. Get routine tests if you’re on long-term medications, have health issues, or consume alcohol. Early consultation helps prevent complications in the liver and kidneys.
🚭 Habits (Alcohol and Smoking): These habits can negatively impact both kidneys and the liver over time.
What does LFT and KFT (Liver Function Test & Kidney Function Test) measure?
Contains 19 testsThe LFT and KFT (Liver Function Test & Kidney Function Test) assesses key indicators of liver and kidney health. LFT is a group of tests that assesses the levels of liver enzymes, proteins, and bilirubin. These components help assess overall liver health and detect potential liver diseases. KFT with electrolytes assesses kidney function. This package measures various parameters, including creatinine, urea, uric acid, and electrolytes (sodium, potassium, and chloride). It may indicate inflammation, infection, or functional damage in the kidneys.
The LFT (Liver Function Test) helps determine the health of the liver by measuring various key markers in the blood, such as bilirubin, enzymes, and proteins. These components help assess inflammation, infection, diseases, etc., of the liver and monitor the damage due to liver-related issues.

The KFT with Electrolytes (Kidney Function Test with Electrolytes) test determines the health of your kidneys. It evaluates parameters such as creatinine, blood urea nitrogen (BUN), uric acid, electrolytes (sodium, potassium, and chloride), blood urea, and the BUN/creatinine ratio. This test also helps indicate possible kidney disorders like inflammation, infection, or functional damage.

BUN/Creatinine Ratio
The BUN/Creatinine Ratio test helps compare the levels of blood urea nitrogen to that of creatinine in your body. Urea is a waste product that is formed in the liver when you eat protein, which is then metabolized into amino acids. This process leads to the production of ammonia that is further converted into urea. Later, the urea is passed out of your body through the urine. On the other hand, creatinine is a byproduct produced by muscles during energy production. Therefore, the more muscle you have, the more creatinine your body produces. The kidneys remove both the urea and creatinine via urine, and this test determines how well your kidneys are functioning.
