Hi what causes high ggt, ast and alt? no hepatitis and don't drink alcohol or do drugs any relations to high ldl and high triglycerides?

Not sure.: Roy, there are entire text books written about what causes abnormal liver tests. There could be many different possibilities. If your liver tests are abnormal, the minimum that you need is a repeat of the tests in 1 to 2 months. If they are still elevated, then further evaluation will be necessary. Be sure to follow up with your doctor. Do not ignore this. Good luck.
