What is a troponin test? Troponin is known as a protein that is released in your blood after a heart attack. Medical doctors measure your cardio troponin levels to determine if you are going to have a heart attack. If your lab results show that your levels are below the 99th percentile, then it means you have normal function.

If you have higher levels, it means you could potentially have a heart attack or cardiac problem. Conducting a troponin test is a more accurate test than implementing other blood tests like a CPK isoenzyme test. After getting the results of a troponin test it can help get you a treatment sooner.

A troponin test is executed through a standard blood test.  A healthcare medical professional draws blood through the vein in your arm. After they take the blood sample the healthcare medical professional will assess your troponin levels to see if there is a potential heart attack.

If your levels or low after experiencing chest pain, then you probably didn’t suffer a heart attack. If your levels are high, then it is probably likely that you could have a heart attack. So, this test will accurately tell you if you are at a high risk of a heart attack or heart damage.

Other tests you can do alternatively to the troponin test is:

  • CT scan
  • Chest X-ray
  • Echocardiogram

The types of symptoms that would require someone to take a troponin test is:

  • Nausea
  • Dizziness,
  • Chest Pain
  • Sweating profusely
  • Shortness of breath
  • Lightheadedness

If your Troponin, (TnL levels) are above 40ng/L then it is considered elevated.  Some of the heart conditions that can contribute to high troponin levels are:

  • Cardiomyopathy is known as a weakened heart.
  • Endocarditis is the inflammation of the inner layer of the heart.
  • Myocarditis is the inflammation of the heart muscle.

Some of the other causes of high troponin levels are:

  • Diabetes
  • Stroke
  • Kidney disease
  • Intestinal bleeding
  • Hypothyroidism
  • A sepsis infection
  • Kidney disease

The Bottom Line is the best test to determine if you are at a high risk for heart attack or experience extreme chest pain is conducting a troponin test.
