How to reduce bun creatine ratio?

Don't treat a lab: Bun/creatinine ratio varies with hydration, diet, and kidney status; if high and the person's kidneys aren't working well, they may just be dry or shocky. You can lower your ratio simply by drinking a few glasses of water. But why? There's no point. I eat a lot of protein and mine tends to be a bit high, but that doesn't mean i'm sick. The big picture is everything.
