Topic Overview
A comprehensive metabolic panel is a blood test that measures your
sugar (glucose) level,
electrolyte and fluid balance,
kidney function, and liver function.
Glucose is a type of sugar your body uses for energy. Electrolytes
keep your body's fluids in balance. They also help keep your body working
normally, including your heart rhythm, muscle contraction, and brain function.
The kidneys help keep the right balance of water, salts, and minerals in the
blood. They also filter out waste and other unneeded substances from the blood.
The liver filters blood, helps with digestion, and produces some vitamins and
other substances that the body needs. It also controls the amounts of glucose,
protein, and fat in the blood and releases substances that keep your
immune system healthy.
Your doctor may use this test to check on a medical condition,
such as
high blood pressure, or to help diagnose a medical
condition, such as
diabetes.
This panel measures the blood levels of sodium, potassium,
calcium, chloride, carbon dioxide, glucose, blood urea nitrogen, creatinine,
protein, albumin, bilirubin, and liver enzymes. For more information, see the

You may be asked to stop eating and drinking for 10 to 12 hours
before this blood test.
