BUN and creatinine test

[Cuz]

Cuz, both creatinine and BUN elevated are dangerous.

Yes creatinine is higher the more mass you carry, and your kidneys may need more time to filter it out. But BUN is not related to muscle mass, it is waste from protein digestion. So yes, it is indicative of kidney disease. The higher the values, the higher the stage of kidney disease, usually not reversible.

Right, the BUN i figured was coming mostly from my over eating and too many protein shakes.
