Collect

At EH, MH OS, SJ:  One 3.0 mL Light Green-Lithium Heparin, Blood
At JC:  One Dark Green (Li)

Specimen Preparation

 Specimens must be centrifuged at 3000G for 5-6 minutes as soon as possible after collection. 

Storage/Transport Temperature

Specimens must be centrifuged at 3000G for 5-6 minutes as soon as possible after collection.  Samples are stable at room temperature for up to 8 hours.  Specimens may be refrigerated at 2-8 C for up to 48 hours.  Samples that must be stored longer than 48 hours must be poured off into an aliquot tube and frozen at -20 C.

OS Lab Female <12 ng/L

Critical >=500 ng/L

Interpretive Data



High-sensitivity Troponin-I (HS Troponin-I) results should be interpreted in light of the total clinical presentation of the patient, including: symptoms, clinical history, ECG findings, data from additional tests, and other appropriate information.  An elevated HS Troponin-I level alone is not sufficient to diagnose myocardial Infarction.  Other conditions resulting in myocardial injury can cause elevated troponin levels.  Serial sampling is recommended to detect the temporal rise and/or fall of troponin levels characteristic of myocardial Infarction.

Troponin results differ between methods due to selection of testing instrumentation. Do not use results between different Emory laboratories interchangeably. 

Potential interferences: human anti-animal antibodies, rheumatoid factor, fibrin, alkaline phosphatase above 400 U/L, asfotase alfa (i.e. Strensiq).
