Hi Doctor, my question is this , my wife s blood test showed a high level of bun/creatinine and aigh level of potassium .what is the cause of this , and should I be concerned? a previos blood test taken in2010 showed a high level of bun creatinine, but not a high level of potassium.thanks
Hello, high bun and creatinine usually indicates renal failure. Since she's had increased values in the past, its probably chronic renal failure (CRF). CRF may cause increased potassium levels. The severity depends on how high they are. If her potassium is higher than 6mEq/L then you should immediately contact your doctor for investigation. If the ratio of bun to creatinine is high (>20) then she can try Chat Doctor.
