JP drain: The original suction drain. The drain itself is inside the body. It is made of Teflon and has multiple drainage holes. The drain is connected to clear plastic tubing which is usually sutured to the skin at the point it leaves the skin. The tubing connects to a bulb reservoir. The bulb, when squeezed empty, applies constant suction to the drain and pulls the fluid out of the body.
Cardiac Enzyme Studies. Cardiac enzyme studies measure the levels of enzymes and proteins that are linked with injury of the heart muscle. These include the enzyme creatine kinase (CK), and the proteins troponin I (TnI) and troponin T (TnT).
Aldolase is an enzyme that helps convert glucose into energy. It is found throughout the body but is primarily found in high levels in muscle tissue. Because aldolase levels are elevated in the bloodstream when a person has muscle damage, the aldolase blood test may be ordered to diagnose and monitor certain conditions related to skeletal muscle. It largely has been replaced by other muscle enzyme tests, especially CK (creatine kinase).
