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


What is LFT and KFT (Liver Function Test & Kidney Function Test)?

This package comprises a liver function test (LFT) and a kidney function test (KFT) with electrolytes that help evaluate liver and kidney functions and detect any disorders associated with these organs. In addition, this package also assesses the pH and water balance in the body.

The liver is the largest organ in our body and performs various vital functions, including the metabolism of nutrients like fats, proteins, carbohydrates, and certain medicines. It also cleanses the blood (a process called detoxification) by converting toxins into waste products. On the other hand, the kidneys play a vital role in removing waste, toxins, and extra water from the body. They maintain a healthy balance of water, salts, and minerals like calcium, sodium, potassium, and phosphorus. Additionally, the kidneys control the blood pressure and the body’s pH balance, produce hormones for RBC production, and promote bone health. Together, both the liver and kidneys play essential roles in maintaining overall health.

An LFT and KFT (Liver Function Test & Kidney Function Test) plays a crucial role in screening and diagnosing liver problems, like fatty liver disease, cirrhosis, jaundice & hepatitis, and kidney diseases, like kidney stones, urinary tract infections, and gout. This test also helps the physician to initiate appropriate treatment timely and avoid further complications. This package can also effectively monitor ongoing treatment for existing liver or kidney issues. Usually, no special preparation is required for this test; eat and drink as per your daily routine. 

Test result ranges are approximate and may differ slightly between labs depending on the methodology and laboratory guidelines. Talk to your doctor about your specific test results. Narrate your complete medical history to help them correlate your clinical and laboratory findings. The test results will help the doctor determine your medical condition and formulate your treatment plan.
