Final answer:
Liver function tests, including the measurement of enzymes in the blood, are used to evaluate alcohol abuse.
Step-by-step explanation:
Liver function tests are used to evaluate alcohol abuse. These tests include the examination of liver function through the measurement of enzymes in the blood, such as alanine aminotransferase (ALT), aspartate aminotransferase (AST), and gamma glutamyl transpeptidase (GGT). Additionally, general laboratory testing can be done to check for signs of related conditions, such as infection or anemia.
