Hello - thanks for asking your questions.
1) Magnesium salicylate is an NSAID-formulation and it is possible that they can increase liver function tests.
2) As above - all NSAIDS, including Motrin, can increase liver function tests.
3) Without personally knowing the situation at the hospital, I cannot comment on what may or may not happened.
4) Again, it is possible - but there is not enough information to make a diagnosis. There are many, many reasons why liver function tests are elevated. Alcohol and medications are two possibilities. An elevated GGT by itself is insufficient to make a diagnosis of alcohol abuse.
A twofold elevation in GGT in combination with an AST:ALT ratio of 2:1 strongly suggests alcohol abuse.
Followup with your personal physician is essential.
This answer is not intended as and does not substitute for medical advice - the information presented is for patient education only. Please see your personal physician for further evaluation of your individual case.
Note: here are the additional readings that I had been told to look at:
AST (SGOT) first test 17 second test 35
ALT (SGPT) first test 28 second test 60
Thank you very much.
