Cardiac troponin T (cTnT) assessment using incompletely filled K 2 EDTA blood tubes is reliable
DOI: 10.31744/einstein_journal/2024CE0613
Dear Editor,
Cardiac troponin testing, which includes the measurement of cardiac troponin I (cTnI) or T (cTnT), is the mainstay of diagnosing acute coronary syndrome, especially in non-ST-elevation myocardial infarction (NSTEMI), in which elevated cTnI or cTnT is the only objective parameter. ( ) Ensuring quality throughout the testing process is essential for maintaining the diagnosis integrity. The receipt of underfilled samples is common in clinical laboratories, ( ) and this could impair the results of some immunoassays. ( ) Therefore, this study aimed to investigate the potential impact of underfilled K 2 EDTA blood tubes on cTnT assay results.
