Basic metabolic panel
Alternate Names : SMAC7, Sequential multi-channel analysis with computer-7, SMA7, Metabolic panel 7, CHEM-7
The basic metabolic panel is a group of blood tests that provides information about your body's metabolism.
Why is the Test Performed?
This test can be used to evaluate kidney function, blood acid/base balance, and your levels of blood sugar, and electrolytes. Depending on which lab you use, a basic metabolic panel may also check your levels of calcium and a protein called albumin.
How is the Test Performed?
Blood is drawn from a vein, usually from the inside of the elbow or the back of the hand. The site is cleaned with germ-killing medicine (antiseptic). The health care provider wraps an elastic band around the upper arm to apply pressure to the area and make the vein swell with blood.
Next, the health care provider gently inserts a needle into the vein. The blood collects into an airtight vial or tube attached to the needle. The elastic band is removed from your arm.
Once the blood has been collected, the needle is removed, and the puncture site is covered to stop any bleeding.
In infants or young children, a sharp tool called a lancet may be used to puncture the skin and make it bleed. The blood collects into a small glass tube called a pipette, or onto a slide or test strip. A bandage may be placed over the area if there is any bleeding.
How to Prepare for the Test?
You should not eat or drink for 8 hours before the test.
How will the Test Feel?
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.
