Liver Function Test (LFT)
The Liver Function Test (LFT) is an essential diagnostic tool used to assess the overall health and performance of your liver by measuring specific proteins, enzymes, and bilirubin levels in your blood. It is highly beneficial because the liver is a silent organ. It often does not show obvious symptoms until significant damage has occurred. By getting this test, you can detect early signs of inflammation, infection (like Hepatitis), or scarring (Cirrhosis) long before they become critical. Additionally, it helps your doctor monitor the side effects of certain medications that may stress the liver and ensures that bile is flowing correctly, allowing for timely intervention and better long-term health outcomes.

Liver Function Test (LFT)
The liver is an essential organ in the body, often referred to as a silent organ because it may not exhibit noticeable symptoms of damage or disease until the damage is advanced. This characteristic makes it vital for individuals to be proactive about liver health. One of the primary tools for assessing liver function is the Liver Function Test (LFT). This test is designed to evaluate how effectively the liver is performing its various functions by measuring a comprehensive panel of enzymes, proteins, and bilirubin levels in the bloodstream.
Among the key markers assessed during an LFT are SGOT (also known as AST or aspartate aminotransferase), SGPT (ALT or alanine aminotransferase), alkaline phosphatase, total protein, albumin, and bilirubin. Each of these markers provides crucial insights into the liver's health and its ability to metabolize substances, synthesize proteins, and detoxify harmful compounds.
The LFT is typically recommended for individuals presenting with symptoms such as persistent fatigue, jaundice (a yellowing of the skin and eyes), unexplained abdominal pain, or nausea. Additionally, it is advisable for those who consume alcohol regularly, as alcohol can significantly influence liver health. Furthermore, people on medications that may have hepatotoxic effects should also undergo this test to monitor liver function closely. Routine health checkups often include LFTs to catch potential liver issues before they escalate.
