How often can Troponin testing be done?

In accord with published recommendations, serial testing of Troponin I at intervals of 2 to 4 hours for up to 12 to 24 hours is suggested in order to corroborate a single Troponin I result. An elevated troponin alone is not sufficient to make the diagnosis of MI. what is he looking for ....diagnosis of MI

Thanks for Posting in HealthCare Magic.

Diagnosis of myocardial infarction has to be done by a combination of parameters and cannot be done using a single test like Troponins.
These include:
1. Clinical Evaluation
2. Electrocardigram
3. Serm levels of enzymes:
(a) CK-MB (b) Cardiac Troponin (c) Myoglobin (d) LDH
4. Echocardiogram

Enzyme levels can be repeated every 6 - 12 hours to know about the progress of infarction.
In case myocardial infarction is treated, CK - MB levels are monitored every 24 hours to know the effectiveness of thrombolytic treatment.

Hope the information provided is useful.
