ALT is a vital biomarker in toxicology because it helps assess liver function, which is critical when evaluating the effects of toxic substances on the body. The liver is a primary site for the metabolism and detoxification of xenobiotics, making it susceptible to damage from toxic agents such as chemicals, drugs, and environmental toxins. Increased ALT levels in the blood can suggest hepatocellular injury, prompting further investigation into potential toxic exposures.
