This test measures the amount of the enzyme aldolase in the blood. Aldolase is involved in the breakdown of sugars to generate energy in cells. It is very concentrated in muscle tissue. The aldolase test can help detect muscle damage, since damaged muscles can release aldolase into the bloodstream.
Who is a candidate for the test?
The aldolase test is most useful in indicating injury or disease in muscle or liver cells.
How is the test performed?
To measure levels of aldolase, a blood sample is taken from a vein in the arm. First, the skin over the vein is cleansed with an antiseptic. A tourniquet is wrapped around the upper arm to enlarge the veins. A small needle is gently inserted into a vein, and blood is collected for testing in the laboratory. After the tourniquet is removed a cotton ball will be held over the needle site until bleeding stops.
