Is a troponin level of 1 high?
For example, the normal range for troponin I is between 0 and 0.04 ng/mL but for high-sensitivity cardiac troponin (hs-cTn) normal values are below 14ng/L. Other types of heart injury may cause a rise in troponin levels.
What does troponin 1 indicate?
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.
What is normal range of Trop I?
Troponin test result ranges They are: Troponin I: 0 – 0.04 ng/mL. Troponin T: 0 – 0.01 ng/mL.
What does a troponin level of 0.01 mean?
Normal range Probable heart attack. 0–0.04 ng/ml. Above 0.40 ng/ml. Having a result between 0.04 and 0.39 ng/ml often indicates a problem with the heart. However, a very small number of healthy people have higher-than-average levels of troponin.
What does a troponin level of 0.015 mean?
What are troponin I and T levels in a heart attack?
Cardiac troponin I and T are biomarkers of cardiac injury, so they are usually included in tests following a suspected heart attack. Normally either troponin I or T levels are tested but not usually both, since levels of each provide the same information.
Are troponin I levels elevated after elective direct current cardioversion?
Conclusions: Cardiac troponin I levels are either normal or minimally elevated after elective direct current cardioversion, suggesting that subtle myocardial injury can be caused by direct current transthoracic shocks.
What is the 99th percentile of troponin concentration?
Clinical Interpretation The 99th percentile concentration for the Beckman High Sensitivity Troponin assay is 0.03 ng/mL. According to current consensus guidelines (Newby 2012), troponin results that exceed the 99th percentile concentration are strongly suggestive of cardiac injury, which can be from many causes (see below for examples).
What is another name for troponin?
According to the National Institutes of Health, sometimes troponin is called other names, such as: 1 cardiac troponin I (cTnI) 2 cTnT 3 cTN 4 and others
