I am sorry for the delay, but I got called away from the computer after I posted the request for information.
Most of these lab changes are not significant, but since several of them pertained to the liver, iron metabolism, and signs of inflammation, it is worth considering whether there is iron overload. When iron overload occurs, it tends to primary be a problem in the liver and cause inflammation of the liver.
The ferritin is a protein that reflects iron stores. But it is also a protein that increases as a non-specific response to inflammation. A more sensitive test is the iron saturation. The serum iron is normal, but they should have also measured the iron capacity and calculated a saturation level. If that saturation level is elevated, then it would be appropriate to be concerned about iron overload developing. However, if the iron saturation is normal, then there is no reason for concern.
Generally speaking, changes in labs within the normal range are not worrisome, so saying that a lab is higher than it was previously, but still within the normal range is not a concern. The only lab that is slightly abnormal is the GGT, and if the remaining liver tests are normal, it is not a concern. Increases of the AST and ALT within the normal range are not worrisome. These enzymes are very sensitive to liver problems, and we will see liver enzymes elevations into the 100s and 1000s when there is signfiicant liver disease. The levels that you have are not a concern.
The TSH is lower in the normal range and is approaching the lower limit of normal. Since you are having weight loss, it would be an option to check thyroid hormone levels, including T4 and T3 levels, and this would be more of a concern in someone having other symptoms or findings on exam that can be due to hyperthyroidism.
If I can provide any additional information, please let me know.
