Ion selective electrode CHEM-7 is a group of blood tests that provides information about your body's metabolism. The test is commonly called a basic metabolic panel. BUN: 7 to 20 mg/d. L CO 2 (carbon dioxide): 20 to 29 mmol/L Creatinine: 0. 8 to 1. 4 mg/d. L Glucose: 64 to 128 mg/d. L Serum chloride: 101 to 111 mmol/L Serum potassium: 3. 7 to 5. 2 m. Eq/L Serum sodium: 136 to 144 m. Eq/L
