Elevated in a literal sense (ie, higher than physically), I can't help you with.
However, the prefixes 'super' and 'hyper' (as well as 'over' and extra' but less so) all have a connotation of elevated in a more abstract sense. Hyperglycemia is elevated blood sugar, hypercritical is unusually critical, superannuated is too old, superman is above man, and so on. I know that's not perfect, but it's something, depending on what you're looking for.
