Testing Algorithm

When the initial (baseline) specimen is collected, the 2-hour troponin test will be added and then collected and performed 2 hours after the initial collection (acceptable collection is anywhere between 1:45-5:45 hours). A 2-hour delta value will be reported (a comparison between the 2-hour value and the baseline value) along with an interpretation.

 

When either the 2-hour troponin delta is greater than 3 ng/L (interpreted as Indeterminate or Changing) or the initial (baseline) value is greater than or equal to 100 ng/L (regardless of delta), the 6-hour troponin test will be collected and performed 6 hours after the initial collection (acceptable collection is anywhere between 5:45-12 hours).
