[|AI|]  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.
