The troponin test is performed to evaluate the amount of troponin T and troponin I proteins in the blood, which are released in case of damage to the heart muscle, for example in the event of a heart attack.the higher the amount of these proteins in the blood.
Thus, in healthy people, the troponin test usually does not identify the presence of these proteins in the blood, considered a negative result. Normal blood troponin values are:
- In some cases.
- This test may also be controlled with other blood tests.
- Such as myoglobin or creattinophosphokinase (CPK) measurement.
- Understand what the CPK test is for.
The test is performed from a blood sample that is sent to the laboratory for analysis, for this type of clinical analysis no preparation is necessary, such as fasting or avoiding medication.
This test is usually prescribed by your doctor in case of suspected heart attack, for example when symptoms such as severe chest pain, shortness of breath, or tingling in your left arm occur, for example In these cases, the test also repeats 6 and 24 hours after the first test Look for other signs that may indicate a heart attack.
Troponin is the main biochemical marker used to confirm the heart attack, its blood concentration begins to increase 4 to 8 hours after the heart attack and returns to normal concentration after about 10 days, which may tell your doctor when the test was performed.is the main marker of infarction, troponin is usually measured with other markers, such as CK-MB and myoglobin, whose blood concentration begins to increase by 1 hour after the infarction.Learn more about the myoglobin test.
The troponin test may also be ordered because of other causes of heart damage, such as angina, which gets worse over time but shows no symptoms of a heart attack.
The result of the troponin test in healthy people is negative, as the amount of protein released into the blood is very low, with little or no screening, so if the result is negative between 12 and 18 hours after heart pain, it is highly unlikely that a heart attack has occurred and there are more likely to be other causes , such as excessive gases or digestive problems.
When the result is positive, it means there is an injury or a change in heart function.Very high values are usually a sign of a heart attack, but lower values may indicate other problems such as:
Normally, blood troponin values are altered for about 10 days and can be evaluated over time to ensure that the lesion is treated correctly.
