Troponina ultrasensible

R.E.B.E.L. EM
R.E.B.E.L. EM - February 6, 2014 - By Salim Razaie
"Troponin testing is an important component of the diagnostic workup and management of acute coronary syndromes (ACS). The increasing sensitivity of troponin assays has lowered the number of potentially missed ACS diagnoses, but this has also created a diagnostic challenge due to a decrease in the specificity of the test. From 1995 to 2007, the limit of troponin detection fell from 0.5 ng/mL to 0.006 ng/mL (see below graph). Robert Jesse summed up this frustration with the following quote: 
When troponin was a lousy assay it was a great test, but now that it’s becoming a great assay, it’s getting to be a lousy test...
Conclusion:
hsTn is the preferred biomarker for the diagnosis of AMI, but remember that conditions other than AMI may cause acute and chronic elevations."
