Creatine Phosphokinase -MB (CKMB/CPKMB)

The Creatine Phosphokinase Myocardial Band (CPK MB) test measures the levels of CPK MB (a specific isoenzyme of creatine phosphokinase) in the blood. When heart muscle cells are damaged, as in a heart attack, CPK MB levels rise in the blood. This makes the test valuable for identifying heart damage.

In addition to heart-related conditions, the CPK MB test can also indicate skeletal muscle injuries or inflammation. Elevated CPK-MB levels can indicate heart muscle damage and are often correlated with Troponin I and Troponin T levels for a more comprehensive assessment of cardiac injury.

For reliable and convenient testing in Bangalore, book your CPK MB test today and gain insights into your heart and muscle health—all from the comfort of your home.

The Creatine Phosphokinase Myocardial Band (CPK MB) test measures a single parameter – the blood levels of the enzyme creatine phosphokinase-myocardial band (CPK MB).

Creatine phosphokinase is an enzyme that contributes to the synthesis of energy in the body. It plays a key role in supporting tissues that need a lot of energy, like your muscles, heart, and brain. There are three types of creatine phosphokinase: CPK MM, which is mostly found in skeletal muscles, CPK MB, which is mostly located in the heart, and CPK BB, which is mostly found in the brain. When muscles or tissues are injured, creatine phosphokinase escapes into the bloodstream. This makes it useful for diagnosing conditions like muscle injuries, heart attacks, or other health issues. Doctors can check the specific type of creatine phosphokinase to understand where the damage is happening. For example, CPK MB is more related to heart issues, while CPK MM is linked to muscle problems. Thus, a Creatine Phosphokinase test can provide valuable insights into muscle and tissue health, helping identify the root cause of symptoms and guiding appropriate treatment.

When scheduling a Creatine Phosphokinase test at home, please make sure the following preparations are followed:

Prerequisites

Fasting is generally not required before taking the Creatine Phosphokinase test. 3 However, consult your doctor for specific instructions based on your condition.

Best Time to Get Tested

The Creatine Phosphokinase test can be booked at any time of the day.

Who Should Get a Creatine Phosphokinase Myocardial Band (CPK MB) Test?

This test is recommended for individuals experiencing signs of heart damage like chest pain or sweating.

Cautions Before Taking Creatine Phosphokinase Myocardial Band (CPK MB) Test

Typically, no special preparation is required for the Creatine Phosphokinase test. However, strenuous physical activity and alcohol consumption should be avoided for a few days before the test as it may temporarily elevate creatine phosphokinase levels. Inform your doctor about any medications you are taking, as some drugs or supplements can influence test results. Always discuss your health history and recent activities with your doctor for accurate interpretation.

Your doctor may recommend a Creatine Phosphokinase Myocardial Band (CPK MB) test if there are concerns about a possible heart attack. Common heart attack symptoms include:

• A tight chest sensation, squeezing, or heavy.

• Sudden, unexplained sweating.

• Unusual fatigue or exhaustion.

• Nausea or episodes of vomiting.

• Pain that radiates to the neck, back, jaw, or left arm.

• Difficulty breathing or shortness of breath.

• Feeling lightheaded, dizzy, or faint.

If you are experiencing these symptoms, the CPK MB test can help determine if heart muscle damage has occurred.
