During Lipitor (atorvastatin) therapy, several liver function tests are typically conducted to monitor the potential impact of the medication on the liver. These tests may include:

1. Alanine transaminase (ALT) test: ALT is an enzyme found in the liver. When the liver is damaged or inflamed, ALT levels in the blood increase.

2. Aspartate transaminase (AST) test: AST is another enzyme found in the liver, heart, and other organs. Elevated AST levels can indicate liver damage or disease.

3. Alkaline phosphatase (ALP) test: ALP is an enzyme found in various body tissues, including the liver and bones. High ALP levels can suggest liver or bone disorders.

4. Total bilirubin test: Bilirubin is a yellow pigment produced by the liver when it breaks down old red blood cells. Elevated bilirubin levels can indicate liver problems or diseases.

5. Albumin test: Albumin is a protein produced by the liver. Low albumin levels can indicate liver disease or other health issues.

These tests help healthcare professionals monitor the patient's liver function during Lipitor therapy and ensure the medication's safety and efficacy. Regular monitoring is essential, especially during the first few months of treatment or in cases of pre-existing liver disease.
