Clots can occur in veins or arteries, which are vessels that are part of the body's circulatory system. While both types of vessels help transport blood throughout the body, they each function differently. Veins are low-pressure vessels that carry deoxygenated blood away from the body's organs and back to the heart.
The CPK blood test is a laboratory test that measures creatine phosphokinase (CPK), which is one of the enzymes found in the brain, heart, and skeletal muscles. This is a useful test for helping doctors to diagnose problems such as muscle damage, heart attack, and related conditions.slide 1 of 4.urpose. When the CPK level in the blood is very high, it often means there has been injury or stress to the heart, skeletal muscle tissue, or even the brain. This is because CPK leaks into the bloodstream whenever this type of damage occurs.
Liver function tests check the levels of certain enzymes and proteins in your blood. Levels that are higher or lower than normal can indicate liver problems. Some common liver function tests include: 1  Alanine transaminase (ALT). 2  ALT is an enzyme found in the liver that helps your body metabolize protein. 3  When the liver is damaged, ALT is released into the bloodstream and levels increase.
