Test Name/Synonym:

Troponin T, Roche H232 (CTN, CTNT) - South Zone

LABID (Connect Care):

LAB139

Primary Container:

DARK GREEN – LIHEP NO GEL

Alternate Containers:

MINT LIHEP PST

Processing:

Storage: 8 hours at room temperature.

Method and Interpretation of Results:

Connect Care/Netcare Reporting	Interpretation
Less than 0.040 ug/L	Troponin T value not consistent with acute myocardial infarction, providing the sample was collected more than 6h from onset of symptoms. Repeat troponin testing 6 to 8 hours after the initial sample should be considered to reliably exclude myocardial infarction. Please note that patients with ischemic ECG changes and/or high-risk clinical presentations should be further evaluated irrespective of troponin results.
Greater than or equal to 0.040 ug/L and less than or equal to 0.100 ug/L	Troponin T value is inconclusive for acute myocardial infarction and may be due to myocardial injury. Repeat troponin testing 6 to 8 hours after the initial sample is recommended for all patients to reliably exclude myocardial infarction. Please note that patients with ischemic ECG changes and/or high-risk clinical presentations should be considered for further evaluation irrespective of troponin results.
Greater than 0.100 ug/L	Clear elevation of Troponin T consistent with acute myocardial injury or infarction in the appropriate clinical context. Repeat troponin testing 6 to 8 hours after the initial sample may be helpful to assess for ongoing myocardial injury. TnT greater than 0.10 µg/L may be observed in several nonthrombotic cardiac and systemic diseases (most commonly – acute PE, acute pericarditis, acute or sever HF, myocarditis, sepsis and/or shock.
Greater than 2.000 ug/L	Clear elevation of Troponin T consistent with acute myocardial injury or infarction in the appropriate clinical context. Repeat troponin testing 6 to 8 hours after the initial sample may be helpful to assess for ongoing myocardial injury. TnT greater than 0.10 µg/L may be observed in several nonthrombotic cardiac and systemic diseases (most commonly – acute PE, acute pericarditis, acute or sever HF, myocarditis, sepsis and/or shock.

Additional Test Information:

Reporting units displayed on the h232 Cardiac Reader may not match Connect Care/Netcare reporting. Please ensure that you are interpreting Troponin T results from the Roche h232 appropriately based on reporting units, because ng/L and ug/L are not equivalent (meter display versus Connect Care/Netcare).
