Test Code LAB123123 Troponin High Sensitivity

Useful For

  • Aiding in the diagnosis of Myocardial Infarction.  As a result of its high tissue‑specificity, cardiac troponin T (cTnT) is a cardio‑specific, highly sensitive marker for myocardial damage.
  • Elevated concentrations of cTn can also occur in other clinical conditions such as myocarditis, heart contusion, pulmonary embolism and drug‑induced cardiotoxicity.

Methodology

Electrochemiluminescence Immunoassay (ECLIA)

Performing Laboratory

Bozeman Health Laboratory Services

Specimen Requirements

Specimen Type: Plasma
Container/Tube: Light-green top (lithium heparin gel)
Specimen Volume: 1 mL
Specimen Minimum Volume: 0.5 mL

Specimen Rejection: 

  1. Hemolyzed samples may falsely depress results and will be rejected.
  2. Samples should not be taken from patients receiving therapy with high
    biotin doses (i.e. > 5 mg/day) until at least 8 hours following the last biotin
    administration.
