All levels are within normal range.
Abnormal liver function tests indicate that the liver is
inflamed or is not functioning normally.
Elevated enzyme levels
indicate liver inflammation (hepatitis), which may be a clue that a viral
infection is present.
What To Think About
Elevated liver enzymes may be caused by something other than mono, including other viral infections (such as
hepatitis B); severe bacterial infection; heart disease; heart attack; bone,
muscle, and joint injuries; and certain cancers. So liver function
tests alone are not a reliable way to confirm a diagnosis of mono.
If your liver enzymes are elevated because of mono, they will return to
normal without treatment after the illness goes away.
