What is the Meaning of Liver Function Tests?

Liver Function Tests (LFTs) are a group of clinical blood assays designed to assess the operational status of the liver by measuring specific enzymes, proteins, and metabolites in the serum. Key markers often include alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), bilirubin, and albumin. These tests are utilized to screen for, diagnose, and monitor hepatic damage or disease, providing crucial insight into the organ's synthetic and excretory capabilities.

What is the Origin of Liver Function Tests?

This is a purely clinical term, originating from the necessity to objectively quantify the physiological health of the liver. The tests themselves are based on decades of biochemical understanding of the liver's role in metabolism and cellular integrity. They are a routine part of a comprehensive metabolic panel, essential for monitoring medication safety and systemic health.

What is the Mechanism of Liver Function Tests?

The measured values in LFTs reflect different aspects of hepatic function. Elevated levels of transaminases (ALT and AST) indicate hepatocellular injury, as these enzymes leak into the bloodstream when liver cells are damaged. Bilirubin measures the liver's ability to conjugate and excrete waste products, while albumin and clotting factors reflect its synthetic capacity. Clinicians interpret the pattern of these results to determine the nature and severity of the underlying hepatic pathology.
