With coagulation tests, obtaining results rapidly is of critical importance as information from these tests is used by clinicians treating severe trauma patients and patients requiring thrombolytic therapy when, for example, deciding whether to provide blood transfusions or determining patient prognosis. However, if tests are carried out in line with the “Consensus guidelines on coagulation test specimen handling” [2016; Japanese only], the time required to obtain results is actually increased, whereas shortening that time is necessary. Paying particular attention to TAT, we compared CP3000 from Sekisui Medical Co., Ltd., and CS-2000i from Sysmex Co., Ltd. Plasma samples from 15 volunteers were obtained and assayed using both analyzers for those tests that happened to be required on a random day. The time from the start of analysis to obtaining all results was 21 min and 20 s on the CP3000 and 53 min and 52 s on the CS-2000i. From these results, we found that even if the centrifugation conditions were changed to 2,000 g and 10 min, as per the 2016 guidelines, the time from sample arrival to final results was shortened. By using CP3,000, even when following the latest guidelines, results can be obtained more quickly than with the previous assay method even during busy periods when large numbers of samples arrive at the laboratory concurrently.
