Blood Tests: What Is A ‘Basic Metabolic Panel’?

1. Glucose

Glucose is the type of sugar that your body uses for energy. 

What’s normal: 70 to 99 mg/dL (after 8 to 12 hours of not eating).

  •  What’s normal: 70 to 99 mg/dL (after 8 to 12 hours of not eating).
  •  What abnormal results can mean: If there’s too much, then it can mean diabetes or prediabetes. If there’s too little, it could mean hypoglycemia.

2. Calcium

Calcium is needed for many body functions, including building bones, heart function, muscle contraction and nerve signaling. 

  • What’s normal: 8.5 to 10.2 mg/dL.
  • What abnormal results can mean: Kidney/liver problems, bone disease, thyroid disease, cancer and malnutrition

3. Electrolytes

Electrolytes are minerals that maintain fluid levels and chemical balance in your body. 

  • What’s normal: Bicarbonate (total) 18 to 30 mEq/L; Chloride: 98 to 106 mEq/L; Magnesium: 1.8 to 3.6 mg/dL or 1.5 to 3.0 mEq/L; Phosphorus: 3 to 4.5 mg/dL or 1.8 to 2.3 mEq/L; Potassium: 3.5 to 5.5 mEq/L; Sodium: 135 to 147 mEq/L.
  • What abnormal results can mean: Dehydration, kidney disease, liver disease, heart failure and high blood pressure.

4. Blood urea nitrogen (BUN)

Blood urea nitrogen (BUN) is a waste product that kidneys filter out of your body.

  • What’s normal: 6 to 20 mg/dL.
  • What abnormal results can mean: If there’s too much, then it can mean kidney disease, heart failure or dehydration. If there’s too little, it could mean liver failure or malnutrition.

5. Creatinine

Creatinine is a waste product that kidneys filter out of your body.

  • What’s normal: For men, 0.7 to 1.3 mg/dL. For women, 0.6 to 1.1 mg/dL.
  • What abnormal results can mean:  If there’s too much, then it can mean kidney disease, muscle breakdown or dehydration. If there’s too little, it could mean malnutrition or low muscle mass.

“Metabolism involves any way your body converts or uses energy,” says Dr. Allan. “That includes digestion, breathing, circulation, and functioning of your organs, muscles and nervous system.”
