What Is a Comprehensive Metabolic Panel?

A metabolic workup, also called a comprehensive metabolic panel (CMP), is a set of 14 blood tests done that gives information on the health of a person's kidneys and liver, and also tests blood sugar, blood proteins, and electrolytes (minerals in the body).

The workup -- which goes by many names, including chemistry panel and metabolic panel -- can be helpful in pinning down what's causing a person's illness or disease, or to monitor a chronic disease such as high blood pressure or kidney disease.

It is also often ordered as part of a routine physical or yearly exam. The blood sample used for the CMP is usually taken from the patient after a 10 to 12 hour fast.

The tests included in a metabolic workup are:

  • Blood sugar (glucose)
  • Albumin (a blood protein)
  • Total blood protein
  • Electrolytes: sodium, potassium, calcium, chloride, CO2
  • Kidney tests: BUN, creatinine
  • Liver function tests: ALP (alkaline phosphatase), ALT (alanine amino transferase, also called SGPT), AST (aspartate amino transferase, also called SGOT), bilirubin

As part of a metabolic workup, the doctor may order additional blood tests such as:

What is a Cholesterol Test?

A complete cholesterol test — also called a lipid panel or lipid profile — is a blood test that can measure the amount of cholesterol and triglycerides in your blood.

A cholesterol test can help determine your risk of the buildup of plaques in your arteries that can lead to narrowed or blocked arteries throughout your body (atherosclerosis).

High cholesterol levels usually don't cause any signs or symptoms, so a cholesterol test is an important tool. High cholesterol levels often are a significant risk factor for heart disease.

High cholesterol by itself usually has no signs or symptoms. A complete cholesterol test is done to determine whether your cholesterol is high and estimate your risk of developing heart disease.

A complete cholesterol test, referred to as a lipid panel or lipid profile, includes the calculation of four types of fats (lipids) in your blood:

  • Total cholesterol. This is a sum of your blood's cholesterol content.
  • High-density lipoprotein (HDL) cholesterol. This is sometimes called the "good" cholesterol because it helps carry away LDL cholesterol, thus keeping arteries open and your blood flowing more freely.
  • Low-density lipoprotein (LDL) cholesterol. This is sometimes called the "bad" cholesterol. Too much of it in your blood causes the buildup of fatty deposits (plaques) in your arteries (atherosclerosis), which reduces blood flow. These plaques sometimes rupture and can lead to a heart attack or stroke.
  • Triglycerides. Triglycerides are a type of fat in the blood. When you eat, your body converts any calories it doesn't need into triglycerides, which are stored in fat cells. High triglyceride levels are associated with several factors, including being overweight, eating too many sweets or drinking too much alcohol, smoking, being sedentary, or having diabetes with elevated blood sugar levels.
