Resumen

GUZMAN D, ANA MARÍA  y  QUIROGA G, TERESA. Troponin in the diagnosis of myocardial infarction: An approach from the Clinical Laboratory. Rev. méd. Chile [online]. 2010, vol.138, n.3, pp. 379-382. ISSN 0034-9887.  http://dx.doi.org/10.4067/S0034-98872010000300020.

Among the many biomarkers studied to evaluate myocardial damage, troponin is considered the most sensitive and specific. However, current methodologies present pre-analytical, analytical and post-analytical problems, of which the more significant are the lack of standardization and a high uncertainty in the level of decision or cut-off. It is hoped that a new generation of assays called "ultra sensitive" will improve analytical performance characteristics of the technique and achieve compliance with the internationally recommended quality specifications.

Palabras clave : Biological markers; Myocardial infarction; Troponin.
