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. So, if the result is in this range, a doctor may check for other symptoms and order further tests before making a diagnosis.
What is high level of troponin?
Very high levels of troponin are a sign that a heart attack has occurred. Most patients who have had a heart attack have increased troponin levels within 6 hours. After 12 hours, almost everyone who has had a heart attack will have raised levels. Troponin levels may remain high for 1 to 2 weeks after a heart attack.

How do you treat high troponin levels?
If troponin levels are high (elevated above normal) and the EKG indicates an acute heart attack, you may have cardiac intervention such as a catheterization with angioplasty and possibly stents, or an evaluation for coronary artery bypass graft (CABG) surgery may be required.
What causes false high troponin?
False values can occur due to interferences from heterophile antibodies or human autoantibodies that mimic troponin, that minimic troponin, by linking the capture antibody to detection antibody. Dilution of the samples often fails to cause changes in the values.
