The functioning of the renal and hepatic system can be reflected in both the Creatinine level and the BUN (Blood Urea Nitrogen) level.

1. Creatinine Level: Creatinine is a waste product that's produced by your muscles. Your kidneys are responsible for removing creatinine from your blood. If your kidneys aren't functioning properly, the level of creatinine in your blood can increase. This can be an indication of renal (kidney) dysfunction.

2. BUN Level: Blood Urea Nitrogen (BUN) is another waste product that's produced in your liver and removed from your body by your kidneys. If your liver or kidneys aren't functioning properly, the level of BUN in your blood can increase. This can be an indication of hepatic (liver) or renal (kidney) dysfunction.

The Potassium level and CBC (Complete Blood Count) level can also provide information about your overall health, but they are not as directly related to renal and hepatic system functioning as the Creatinine and BUN levels.
