A troponin test measures the levels of troponin T or troponin I proteins in the blood. These proteins are released when the heart muscle has been damaged, such as occurs with a heart attack. The more damage there is to the heart, the greater the amount of troponin T and I there will be in the blood.
Is 0.06 a normal troponin level?
Laboratories measure troponin in nanograms per milliliter of blood (ng/ml). The University of Washington’s Department of Laboratory Medicine provides the following ranges for troponin I levels: Normal range: below 0.04 ng/ml. Probable heart attack: above 0.40 ng/ml.
What is high sensitive troponin I?
High levels of high‐sensitivity cardiac troponin I are associated with more severe coronary artery disease and its accelerated angiographic progression. In patients with coronary artery disease, high‐sensitivity cardiac troponin I levels can be used to risk stratify and predict future cardiovascular outcomes.
What is the normal range for troponin levels?
Results are given in measurements of nanograms per milliliter (ng/mL). The normal range is between 0 and 0.4 ng/mL. What is an elevated troponin level? High levels of troponin in the blood can indicate that someone has recently had a heart attack, which describes when blood flow to the heart muscle is cut off, causing tissue damage.
What causes high levels of troponin?
Elevated troponin levels may result from sepsis, kidney failure, heart failure, or a traumatic injury to the heart. Very high levels of troponin typically indicate that a person has had a heart attack, which can occur if the blood supply to some of the heart muscle suddenly becomes blocked.
What might explain my elevated troponin level?
Anything above the normal range (0 and 0.4 ng/mL) is considered to be an elevated troponin level in the blood. However, the higher the level is, the more likely it is that a heart attack occurred. What level indicates a heart attack?
How often to check troponin levels?
Troponin levels should be measured at presentation and again 10-12 hours after the onset of symptoms. When there is uncertainty regarding the time of symptom onset, troponin should be measured at twelve hours after the presentation.
