The BD Barricor blood collection tube is an acceptable and robust alternative to the PST for use with the Beckman AccuTnI+3 assay

BD Canada recently released a blood collection tube with a novel mechanical separator called the Barricor. We evaluated this tube as an alternate sample type for cardiac troponin I (cTnI) testing using the Beckman Coulter AccuTnI+3 assay. 3014 paired patient specimens (Barricor, plasma separator tub...

Description
Summary:BD Canada recently released a blood collection tube with a novel mechanical separator called the Barricor. We evaluated this tube as an alternate sample type for cardiac troponin I (cTnI) testing using the Beckman Coulter AccuTnI+3 assay. 3014 paired patient specimens (Barricor, plasma separator tube or PST) were obtained from the emergency departments and cardiac care units of nine hospitals in and around Edmonton, Alberta. After centrifugation, each plasma sample was analyzed for cTnI using the Beckman Coulter AccuTnI+3 assay. In addition, selected samples were analyzed multiple times within a single run or over 4–5days to generate imprecision data for the assay. Repeatability and within-laboratory studies revealed an imprecision of
