Thanks Tina_Marie - Both of those levels are well within the "normal range".
As I understant it, from a bit of reading, most GPs only start to be interested in ASTs over about 40, although they'll want to keep and eye on anything skirting round the edges of the lab's reference ranges - in your case 10-35.
ElderGarth's TSH is probably holding it's own there, although not in the Endo considered optimal range (optimal being someone with good funtion).
In UK, most GPs aren't interested in scores under 5, even where there are symptoms, and of no symptoms exists, don't treat under 10.
Like many things, how well an individual does at a particular level is personal to them, but in isolation and no defitine thyroid concerns, if it were me, I might be looking elsewhere (but not ignoring this altogether, I'd want it tested regularly, as it can change on a day to day basis - pesky stuff!)
He does go through it.
Sorry I don't have any lightbulb stuff here. In your shoes, I'd be as frustrated as heck too.
