ALT is short for alanine aminotransferase, an enzyme present in liver cells. It is one of the enzymes that can be measured in the blood to determine liver damage. When the liver is damaged, more ALT is released into the bloodstream, resulting in an increased ALT level. Therefore, an elevated ALT level can indicate the presence of liver damage.
What Causes an Elevated ALT Level?
ALT levels can be elevated for a variety of reasons, including a viral infection or exposure to certain medications or toxins. In some cases, an elevated ALT level can also be caused by an underlying medical condition, such as cirrhosis or hepatitis.
How Is an Elevated ALT Level Diagnosed?
Diagnosing an elevated ALT level typically involves a physical exam and blood tests. The doctor may also order imaging tests, such as an abdominal ultrasound or a CT scan, to determine the cause of the elevated ALT level.
How Is an Elevated ALT Level Treated?
Treatment for an elevated ALT level depends on the underlying cause. For example, if the ALT elevation is caused by a viral infection, the doctor may prescribe antiviral medications. If the ALT elevation is caused by an underlying medical condition, the doctor may recommend lifestyle changes or medications to manage the condition.
