Hello from JustAnswer.
The primary concern with an elevated iron saturation is whether there is iron overload, which is primarily due to a metabolic condition in which excessive amounts of iron are absorbed from the gut, called hemochromatosis.
We are primarily concerned when the iron saturation is higher, about 60-62%. but it is possible that a lesser elevation in iron saturation could be early in the disease process.
However, regular alcohol intake also can cause an elevation in iron saturation. Alcohol us also can elevate the ferritin level, although you note that your ferritin is normal. Even low levels of alcohol intake can be sufficient to elevate the iron saturation or ferritin, although the effect is greater with higher amounts of alcohol intake. So, in someone that is regularly drinking alcohol, it is not as easy to clarify whether the abnormal lab results are due to the alcohol or to a separate metabolic condition.
If it can be done, the usual next step would be to repeat the iron studies after a period of abstinence from alcohol.
