Abnormal LFTs: there are entire text books written on the causes of abnormal liver tests. They may be indicative of liver problems. The first thing to do is repeat the test in a few weeks to be sure they are truly abnormal. If they are, then a work up of the liver and of the rest of the body, including test for various causes of hepatitis, should be considered. Good luck.

Liver enzyme levels: These levels are close enough to normal for some labs that the reference ranges are needed to properly interpret them. They may be mildly elevated which could be due to a host of possible causes, or could be due to "normal" variation. If they are persistently elevated then further study to look for causes, such as viruses, and a more thorough history should be considered.
