Even a minimally elevated cardiac troponin I
level at hospital admission was associated with having a large pulmonary embolism and increased in-hospital mortality.
Clinical and Angiographic Data for Unstable Angina Patients, According to Relation to Troponin Cutoff Values Cardiac Troponin I
[less than or equal to] 0.
Direct comparison of high-sensitivity-cardiac troponin I
To accommodate the lack of standardization in Troponin I
assays, laboratories should select quality control material at a low value better suited to the 99th percentile URL of their platform.
In 14 patients (29%), myocardial damage was classified as significant based upon an admission cardiac troponin I
greater than 0.
a more cardiac-specific marker than creatine kinase MB fraction, and once troponin levels become elevated they stay high for several days.
1] Recently, elevations in the serum troponin T and troponin I
levels have been used both to test for AMI and to predict adverse cardiac events.
The only high-sensitivity troponin I
assay currently in clinical use (manufactured by Abbott Diagnostics) has enhanced high-sensitivity troponin I
assay precision at very low concentrations, permits quantification of troponin in the majority of persons, and affords the opportunity to define a threshold to rule out MI based on clinical performance rather than analytical imprecision.
27 September 2013 - Beckman Coulter Inc, part of US Danaher Corporation (NYSE:DHR), said Thursday it had received 510(k) approval from the US FDA for its Access AccuTnI+3 troponin I
assay for use on the UniCel DxI series of immunoassay systems.
High sensitive troponin I
and troponin T assays from major manufacturers have been released for use in most of the world.
In a prospective study of 118 consecutive cases of acute pericarditis treated over 2 years, the researchers assessed cardiac troponin I
levels obtained from venous blood samples within 24 hours of symptom onset.
