Hello,
Thanks for the query to H.C.M. Forum.
There are thousands enzymes present in
liver but here we will discuss only about
ALANINE AMINOTRANSFERASE OR
ALT .
Normal value is 5-50 I / U.
A S T ( aspartate aminotransferase ) is found in liver,
cardiac muscle, SKELETAL MUSCLE, kidneys , brain ,
pancreas, w b cs & rbcs in decreasing order of concentration.
While A L T ( as you mentioned in your query ) is found primarily in the liver.
This is high ( if less then 200 than non specific ) 350 IU .
In my opinion please consult a physician and get his opinion as well complete liver function test.
Hope I have answered your question.
If further any question I will help happily.
Good luck for your sister.
Dr. HET
