the ALT number of 857 means?

A recent lab test showed an ALT number of 857. What does a number that high actually mean?

Oops....autoimmune hepatitis elevates ALT. It is not a false elevation.

To add to what Lynn is telling you, high levels can mean acute hepatitis A or C. Although with hep A you would be feeling quite ill. Hep C can be symptom free. thyroid disease can falsely elevate ALT and autoimmune hep can, too. Your doc will likely want to do further testing. Are you feeling sick?

Alanine Aminotransferase (ALT)
What Affects the Test

Reasons you may not be able to have the test or why the results may not be helpful include:

    Taking some herbs and natural products, such as echinacea and valerian.
    Strenuous exercise, injury to a muscle, or injections into a muscle.
    Recent cardiac catheterization or surgery.

What To Think About

    The alanine aminotransferase (ALT) value is often used along with the results of the aspartate aminotransferase (AST) test to obtain the AST to ALT ratio. This value can often help determine whether there is damage to the liver related to alcohol abuse. For more information, see the topic Aspartate Aminotransferase (AST).
    In children with acute lymphocytic leukemia (ALL), very high ALT levels may mean that the disease is likely to progress rapidly.
    Many different conditions can raise ALT blood levels, so other testing is usually needed to interpret an abnormal ALT result.

you really should ask your doctor your liver enzume is elevated above normal but there are many things that could cause this.

High values

High levels of ALT may be caused by:

    Liver damage from conditions such as hepatitis or cirrhosis.
    Lead poisoning.
    Exposure to carbon tetrachloride.
    Decay of a large tumor (necrosis).
    Many medicines, such as statins, antibiotics, chemotherapy, aspirin, narcotics, and barbiturates.
    Mononucleosis.
    Growth spurts, especially in young children. Rapid growth can cause mildly elevated levels of ALT.
