Troponin Blood Test

Troponin is a group of proteins that is usually found in minute quantities in a healthy person. This protein helps in contractions of the heart and muscles surrounding them. Your heart is a fragile muscle that pumps blood throughout your body. Pumping the blood requires regular beating of the heart for the blood to flow without any congestion. However, the heart is a muscle that weakens overtime causing heart problems such as heart attacks.

The troponin test measures troponin levels in your blood. Your troponin levels will be elevated if you had a recent heart attack and/or also prescribed when you had abnormal chest pain.

What is a Troponin Blood Test?

A Troponin blood test is done to evaluate your troponin levels in the blood. Troponin is a protein that is broken into 3 subunits –

  • Troponin C (TnC)
  • Troponin T (TnT)
  • Troponin I (TnI)

Generally, this blood test measures the levels of troponin T or troponin I proteins. When you have heart muscle damage or heart attack, the muscles rupture, and these proteins are released into the bloodstream. The severity of the heart damage will be reflected in higher levels of troponin T and I in your blood.

With the help of Troponin levels in the blood, your physician can diagnose heart attacks or other heart related medical conditions more accurately and provide you appropriate treatment. However, sometimes other medical histories of the patient and more tests like ECG (Electrocardiogram) will be needed to have a clear picture of the heart condition.

What is Troponin & Why is it Important?

When you have a heart attack, the levels of troponin I and troponin T will rise abruptly in your blood within 3 or 4 hours after injury and may remain elevated for 10 to 14 days. This test is also known as a cardiac test, as it is done to know whether you have suffered a heart attack. In acute coronary syndromes (ACS), troponin levels become detectable in the blood after 4-8 hours following the onset of chest pain and remain elevated for 5-9 days.

In a healthy person where there is no heart issues or any historic heart health complications, the troponin levels are present in tiny amounts that are undetectable in the blood. In the event of a heart attack, the damages in heart muscles will release high levels of troponin into the blood.

Troponin I is one of the 3 components of troponin levels in the blood. This protein has a primary function of regulating the contraction of striated muscle, including the muscle that makes up the heart. Thus when there is severe damage in your heart, the troponin levels are heightened.

Troponin Blood Test Normal & High Levels Causes & Treatment
Troponin Blood Test Overview

How is the Troponin Blood test performed?

As the name suggests, the Troponin Blood test is a simple blood test. During this test, a lab technician or a phlebotomist will cleanse the skin with an antiseptic and place an elastic band around the upper arm so that the vein becomes visible and swells with blood. He/she then injects a needle and draws a sample of blood in a test tube. After the blood is drawn, he covers the injected area with a band-aid to stop bleeding. The typical blood specimen is then sent to the lab for analysis.

It takes less than 10 minutes to perform this test.

Is there any preparation required before the test?

There is no special preparation required for the Troponin Blood test, you can continue with your regular activities and other diets.

Are there any risks in the Troponin Blood test?

There is no possible risk or complication in taking the Troponin blood test. You might have slight pain or bruise in the injected area for a very little period.

What does the Troponin Test Result Mean?

Generally, the cardiac troponin levels in your blood cannot be detected with most blood tests, as they are present in undetectable quantities. When there is a slight increase in troponin levels it may be a consequence of heart damage. Extremely high levels of cardiac troponin levels indicate that a heart attack has occurred.

Normal troponin I levels should be less than 0.04 ng/ml. Troponin levels may remain high for more than 10 to 14 days after a heart attack.

Troponin Blood test high

If your troponin I levels show more than 0.40 ng/ml, then you have likely encountered a heart attack.

Causes of high troponin levels are –

  • Abnormally fast heartbeat
  • Blockage of a lung artery due to a blood clot, or tumor cells (pulmonary embolus)
  • Congestive heart failure
  • Coronary artery spasm
  • High blood pressure in lung arteries
  • Inflammation of the heart muscle usually due to a virus (myocarditis)
  • Long-term kidney disease
  • Prolonged exercise (marathons or triathlons)
  • Trauma that injures the heart, such as a car accident
  • A weakening of the heart muscle

Following are some of the medical conditions causing high troponin levels –

  • Cardiac angioplasty
  • Open heart surgery
  • Heart defibrillation or electrical cardioversion
  • Radiofrequency ablation of the heart

High troponin levels are a symptom that indicates recent heart damage/attack, this high levels are not a direct diagnosis, your physician will recommend a follow-up test or ECG to find and address the underlying cause.

How to reduce high Troponin levels in blood?

Extremely high levels of troponin indicate that a person has recently had a heart attack. Reducing the troponin levels depends on what reason you had a high rise in the troponin levels. Your physician will prescribe your medications and if your lifestyle habits need a change then you’ll be informed accordingly.

Following are some of the common treatments of a heart attack include:

  • Clot-dissolving medications
  • Coronary angioplasty, which is a procedure that involves threading a small balloon into the coronary artery to open up the blockage
  • The insertion of a stent — to prop open a blocked blood vessel during an angioplasty
  • Bypass surgery,
  • Ablation, which is a treatment that destroys certain heart cells using radio waves

In order to prevent further heart attacks, your doctor will recommend lifestyle changes if you are overweight or a smoker – quitting the smoking habit and increasing a fiber-rich diet, and exercising regularly will help in avoiding heart attacks in the future. 

Troponin Blood test low

In healthy people, troponin levels are low enough to be undetectable in any blood test. If you’ve experienced chest pain, but troponin levels are still low 12 hours after the chest pain started, then the chances of a heart attack in unlikely.
