Patients with COVID-19 commonly have elevated liver enzyme levels, which is associated with adverse outcomes during hospitalization including increased risk of ICU admission, intubation, and mortality. When assessing these patients, it is important to consider causes of liver injury unrelated to COVID-19. Therapies for COVID-19 may increase liver enzyme levels but are not contraindicated in patients with baseline abnormal liver tests. Liver enzymes should be regularly monitored in all hospitalized patients with COVID-19. Patients with preexisting liver disease such as cirrhosis and those who have received a liver transplant may be an increased risk of severe COVID-19 outcomes.
