Aldolase is a protein (called an enzyme) that helps break down certain sugars into energy. It is found in high amounts in muscle tissue.

A test can be done to measure the amount of aldolase in your blood.

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.

You may be told not to eat or drink anything for 6 hours before the test. Your health care provider will tell you if it's necessary to stop taking any drugs that may interfere with this test. Make sure that your doctor is aware of all drugs you are taking, both prescription and nonprescription.

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 is done to diagnose or monitor muscle or liver damage.
