Background: Barricor™ lithium heparin plasma tubes are new blood tubes that have been introduced to overcome the effects of gel in serum separator tubes (SST) and the shortcomings of standard lithium heparin plasma. We aimed to evaluate Barricor™ tubes as an alternative to serum separator tubes and compare the stability between the tubes. Methods: Forty-four paired samples were collected using both Barricor™ and SST We compared five analytes at baseline (<6 h) and after every 24 h using the Passing-Bablok and Bia nd-Altman plots. Aspartate aminotransferase (AST), potassium (K), phosphate (PO4j, lactate dehydrogenase (LDH), and creatinine were analysed in both tubes. We calculated the percentage difference for each analyte between the baseline and time intervals to assess analyte stability. The percentage difference was compared to the desirable specification for bias and reference change value (RCV). Results: All analytes were comparable at baseline. Statistical differences (p<0.001) became evident after 24 h. PO4, K, and creatinine had a mean difference that exceeded the desirable specification for bias (-9.59%, - 9.35%, and -4.59%, respectively). Potassium was stable up to 24 h in both tubes. LDH showed better stability in SST (144 h vs 96 h). PO4 concentrations were more stable in both tubes with the SST (96 h vs 72 h). Creatinine and AST had the longest stability in both tubes compared to other analytes (144 h). Conclusions: Data demonstrated variability and similarities in analyte concentrations and stability, respectively, in both tubes. [ABSTRACT FROM AUTHOR] |
