TROPONIN T, HIGH SENSITIVITY (TROPT5)

Test Code

LAB8852

Preferred Specimen

1 ml plasma

Instructions

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.

Transport Container

Light green top

Transport Temperature

Refrigerated

Reference Range

Males: < or =15 ng/L

Females: < or =10 ng/L

Changes over serial sampling are considered in evaluation of clinical significance.

Clinical Significance

Troponins are released during the process of myocyte necrosis. While they are cardiac specific, they are not specific for MI and detectable levels may be seen in other disease states that involve the heart muscle (e.g. arrhythmia, acute aortic syndrome, acute heart failure, hypertensive crisis, myocarditis, pericarditis, pulmonary embolism and Takotsubo cardiomyopathy), so that ACC/ESC/AHA guidelines and the Universal Definition of MI recommend serial sampling with a rise or fall in troponin to distinguish between acute and chronic cTn elevations. Results should be interpreted in conjunction with clinical presentation including medical history, signs and symptoms, ECG data and biomarker concentrations.

Performing Laboratory
Currently performed at KH,CH,DH,PH,WH,NF,WGH laboratories.
