Seeing results in a vacuum can be a two-edged sword if you have health anxiety.
Blood tests aren't straightforward. I have them often for various reasons, and they are rarely 100% perfect, as so many things can affect different metrics. It might be something you've eaten, or all sorts of things that throw one result out a bit. If you go back for a repeat test in a few weeks the odds are that that will have repaired but something else is out of kilter. A GP has the ability to read them in conjunction with other things that impact your health.
Re fatty liver - it's not a terrible diagnosis - many older people have it, and it can be reversed with a low-fat, los-sugar diet and exercise. If you have a tendency to overdo alcohol, then cut back on that, too. It's only if it is allowed to progress that you need to be worried - the liver is very forgiving.
