A comprehensive metabolic panel is a group of chemical tests performed on the blood serum (the part of blood that doesn't contain cells).
These tests include total cholesterol, total protein, and various electrolytes. Electrolytes in the body include sodium, potassium, chlorine, and many others.
The rest of the tests measure chemicals that reflect liver and kidney function.
A blood sample is needed. For information on giving a blood sample from a vein, see venipuncture.
You should not eat or drink for 8 hours before the test.
When the needle is inserted to draw blood, some people feel moderate pain, while others feel only a prick or stinging sensation. Afterward, there may be some throbbing.
This test helps provide information about your body's metabolism. It give your doctor information about how your kidneys and liver are working, and can be used to evaluate blood sugar, cholesterol, and calcium levels, among other things.
Your doctor may order this test during a yearly exam or routine check up.
