Comparison of Single and Repeat Centrifugation of Blood Specimens Collected in BD Evacuated Blood Collection Tubes Containing a Clot Activator for Cardiac Troponin I Assay on the ACCESS Analyzer

[摘要] Cardiac troponin I (cTnI) has become a major marker in the diagnosis and monitoring of myocardial damage. On the ACCESSTM analyzer (Beckman Coulter), serum is the biological fluid compatible with both myoglobin and cTnI tests (1). However, residual fibrin (2) and microparticles (2) have been reported to interfere with one or more cTnI assays. Some of these interferences can be avoided with repeat centrifugation of the sample and/or the use of a clot activator (3). The BD VacutainerTM HemogardTM Thrombin glass evacuated blood collection tube (BD Thrombin) contains thrombin as a …
