What Is a Blood Enzyme Test?

An enzyme marker is a blood test used to determine the number of enzymes and proteins found in your blood that may signal tissue damage or disease. Elevated blood enzymes following a heart attack indicate severe heart damage. Increased CPK isoenzyme levels may indicate muscle disease, but elevated liver enzyme levels may indicate liver injury.

The blood enzyme test is a diagnostic technique physicians use to detect whether or not a patient is experiencing or has previously had a heart attack. This test measures the number of enzymes generated by the heart muscle in response to injury, such as during a heart attack.

Concerning blood enzyme Tests

Because patients frequently report chest discomfort or shortness of breath, and because these symptoms can imply various things, healthcare practitioners require a method for narrowing down the possible causes of such symptoms. One such test entails the monitoring of blood enzymes.

Blood enzymes are substances produced by the heart in response to injuries, such as a heart attack or a severe case of angina. There are various blood enzymes, the most prevalent of which is troponin, a protein secreted by injured heart cells. Troponin can be quantified in two forms (T and I), both of which are equally sensitive.

Justifications for blood enzyme Testing

If you believe you have had a heart attack, your doctor will do a blood enzyme test. Additional signs of a heart artery blockage that may necessitate a blood enzyme test include the following:

  • Pain or pressure in the chest
  • Dizziness
  • Weakness or exhaustion
  • Breathlessness
  • Sweating and clammy, cold skin
  • Vomiting or experiencing nausea

How to Prepare for a blood enzyme Test

A blood enzyme test is extremely comparable to any other type of blood test. The procedure will be as follows:

Your doctor will take a small amount of blood, most commonly from your arm near the elbow, using a fine needle. The discomfort should be limited to a pinch or sting.

Blood will be tested, which normally takes only a few minutes.


Because blood enzyme tests are frequently performed urgently, you can expect to receive your findings immediately. The concentrations are given in nanograms per millilitre (ng/ml). This column indicates the amount of the enzyme present in your body. The test is capable of detecting extremely minute amounts of enzyme released.

Your doctor will assist you in comprehending the test results and conduct a physical examination or other tests to obtain a complete picture of the cause of your symptoms. If you have had or are suffering a heart attack, your doctor will discuss treatment options with you, including medication, lifestyle changes, and follow-up care. Your doctor may order numerous enzyme tests to monitor your levels over time.

Seek emergency medical assistance if you’ve had or are having a heart attack or if you’re suffering any other common signs of heart injury. Your doctor can determine whether a blood enzyme test is appropriate for you.

Our cardiologists are board qualified in both general and interventional cardiology. We have nearly 30 providers with decades of experience treating patients with cardiac conditions.

Thus, we must recognise that elevations can be acute or chronic with this test. For instance, if someone has had uncontrolled blood pressure for an extended period, this may result in heart damage. As a result, if that individual has an increased troponin level, they may avoid hospitalisation. What they require is a competent primary care physician who can assist them in lowering their blood pressure. Stress caused by an infection or a brain injury can also cause damage to the heart.

As doctors, we must be astute in reading the results and not automatically assume that someone with a high troponin number is experiencing a heart attack. Institutions must determine how effectively the exam performs in their hands – and how to best leverage its benefits. The rollout must be prudent.
