Blood Test Results: CMP Explained

1 Blood Test Results: CMP ExplainedComprehensive Metabolic Panel (CMP)Definition: Measures kidney and liver function, electrolyte levelsSubstanceWhat It IsReference Ranges *What a Low Number May MeanWhat a High Number May MeanUSAUK/EUAustralia/CanadaGlucose (fasting or non-fasting)Sugar in the blood70-99 mg/dL (fasting)70-125 mg/dL (non-fasting)Hypoglycemia, liver disease , adrenal insufficiency, excess insulinHyperglycemia, certain types of diabetes, prediabetes, pancreatitis, hyperthyroidismSodium (Na)An electrolyte which keeps your body in balance136-144 mEq/LUse of diuretics, diarrhea, adrenal insufficiencyKidney dysfunction, dehydration, cushing 's syndromePotassium (K)

2 An electrolyte and mEq/LUse of diuretics or corticosteroids (such as prednisone or cortisoneAcute or chronic kidney failure, Addison's disease , diabetes, dehydrationChloride (Cl)An electrolyte 96-106 mmol/LEmphysema, chronic lung diseaseDehydration, cushing 's syndrome, kidney diseaseCarbon dioxide (bicarbonate) (CO2)Gaseous waste product from metabolism20-29 mmol/LKidney disease , certain toxic exposures, severe infectionLung diseases, including COPDBUN ( Blood urea nitrogen) A waste product formed in the liver and carried to the kidneys, filtered out of Blood , and excreted through urine7-20 mg/dLMalnutritionLiver or kidney disease , heart failureCreatinineA chemical waste produced by muscle mg/dLLow muscle mass, malnutritionChronic or temporary decrease in kidney functionBUN/creatinine ratio10:1 to 20:1 MalnutritionBlood in bowels, kidney obstruction, dehydrationCalcium (Ca)A mineral stored in the hard part of mg/dLCalcium, magnesium, or Vitamin D deficiency; malnutrition; pancreatitis.)

There are no nationally established reference ranges for CMP and CBC values; instead, each laboratory tests a population and establishes its own reference ranges. Therefore, the reference ranges quoted are only approximate.
