A liver function test (LFT) is a commonly recommended blood test that helps evaluate liver health by analyzing enzymes, proteins, and bilirubin levels. It is widely used to detect liver damage, infections, and metabolic issues at an early stage.
In today’s fast-paced lifestyle, regular liver function testing is important for early diagnosis and prevention of serious liver diseases.
