A PST usually contains lithium heparin as an anticoagulant, and numerous PSTs are available from different manufacturers. To reduce the length of this preanalytical step, the plasma separation tube (PST) and Barricor tube (BD, Franklin Lakes, NJ, USA) were developed. Despite the use of a clot-activation gel, serum separator tubes (SSTs) require approximately 10 minutes each for clotting and centrifugation. For routine chemistry tests, most laboratories receive serum samples that require clotting. Improvements in automation of laboratory instruments and transport technology have reduced TAT, especially for the analysis and post-analysis components. Reducing the turnaround time (TAT) is important in clinical laboratories, especially for emergency and outpatient departments, as it can facilitate faster clinical decision making. Keywords: Barricor tube, Turnaround time, Routine chemical tests, Serum separation tube Incomplete clotting and repeated centrifugation, which occurred frequently when using SST, also decreased after using the Barricor tubes.Ĭonclusions: The Barricor tube is an alternative to SST for routine chemical tests in institutions aiming to reduce TAT, with clinically allowable differences in test results.
The reduction in TAT was attributable to a decrease in centrifugation time. Results: Mean percent differences were 60 minutes decreased from 7.84% to 2.66%, which was approximately one-third of that for SST. TAT indexes were compared before and after using Barricor tube. Methods: We collected venous blood samples from 166 outpatients in Barricor tubes and SSTs and measured 28 routine analytes using an AU5800 instrument (Beckman Coulter, Brea, CA, USA). We verified the impact of Barricor tube on reducing TAT and providing results similar to those obtained using serum separator tubes (SSTs). We evaluated the effects of using the Barricor tube in a stat ( statin) laboratory on the results and turnaround time (TAT) of routine chemical tests. Background: We recently introduced the Barricor (BD, Franklin Lakes, NJ, USA) plasma separation tube, which uses a mechanical separator instead of a gel.
