Testing both troponin types at once may sharpen early MI rule-out

Performing high-sensitivity assays for both cardiac troponin types (hs-TnI and hs-TnT) from a single early blood draw may allow "very early and safe" rule-out of acute myocardial infarction (MI) better than can conventional single-troponin tests, conclude researchers from a new study. But such combined-troponin testing didn't improve MI diagnosis in the analysis, based on a primary cohort of 2225 patients suspected of having MI and a similar 2537-patient validation cohort, both drawn from other studies.
