Creatinine Phosphokinase Test

bout : Enzymes are complex proteins that your body needs in order to work properly. An enzyme called creatine phosphokinase (CPK) is important for muscle function. The CPK isoenzymes test is a way to measure the levels of this enzyme in your bloodstream. This enzyme can be broken into three parts:- 1. CPK 1 : mainly found in our brain and lungs. 2. CPK 2: mostly found in our heart. 3. CPK 3: found in our skeletal muscle. The CPK isoenzymes test checks the levels of these enzymes in your blood. This can help your doctor identify the areas of your body that have been damaged.

The CPK isoenzymes test is similar to other blood tests. It doesn’t require any fasting or special preparation. Before you schedule your blood test, it’s important to tell your doctor about any over-the-counter and prescription medications you’re taking. Some substances can cause elevated CPK, including: 1. Drugs that lower cholesterol 2. Steroids 3. Amphotericin B, which is an antifungal medication.

• help them diagnose a heart attack.
• find the cause of your chest pain.
• find out how much heart or muscle tissue has been damaged.

• dermatomyositis
• polymyositis
• malignant hyperthermia. The test can also determine the gene for muscular dystrophy.

The test is done with a blood sample. A needle is used to draw blood from a vein in your arm or hand. You will probably be asked to make a fist. The technician will use a band to constrict your arm. Once he or she finds a usable vein, the technician will clean the area and then insert the needle. You might feel a small pricking sensation. Once the technician has drawn enough blood, he or she will take the needle out and put an adhesive bandage over the site. In some cases, your doctor may want to repeat the test over several days to see if your enzyme levels change.
