is higher tha reference range.
Your FBS is 176 mg/dl comes in diabetic range if it is for the first time detected you can recheck it FBS and PPBS or you can take GTT.This is also indirectly indicated by your HbA1 c level which is borderline high.
You have not tested for Lipid Profile
then you should get it done as it may be abnormal.
The most coomon causes of high liver enzymes could be Alcohol injury? Viral hepatitis??
If you are over weight there may be fatty liver
which can be confirmed by a Ultrasonography
