Sažetak
Background Cap-piercing technology is a mechanism that has emerged in order to improve the laboratory staff safety by reducing exposure to the biological specimen. The aim of the study was to examine whether cap-piercing technology is reliable for routine use since nonreproducible results were previously noticed for coagulation tests, noticeably fibrinogen concentration that was measured by Sysmex® CS-2500 System coagulation analyzer. Materials and Methods Our study collectively used 58 blood samples from pediatric population standardized for coagulation testing which had their Prothrombin time (PT) measured using coagulometric assay (Dade Innovin, Siemens), fibrinogen concentration measured using coagulometric assay (Dade Thrombin, Siemens), D-dimer concentration measured using immunoturbidimetric assay (Innovance D-dimer, Siemens) and/or Protein C activity measured using spectrophotometric assay (Berichrom Protein C, Siemens) from the capped tube and then the decapped tube. Bland-Altman analysis and Passing-Bablok regression analysis have been used to compare results. Results No significant difference has been observed for any of the previously mentioned tests when Bland-Altman analysis (with Westgard's QC rules) has been used: PT had average BIAS = 0.7% (desirable BIAS = 2.0%), fibrinogen had average BIAS = 0.4% (desirable BIAS = 4.8%), Protein C had average BIAS = 0.2% (desirable BIAS = 13.9%) and D-dimer had average BIAS = 0.2% (desirable BIAS = 8.82%). Passing-Bablok regression analysis showed no significant difference for PT (y = [-0.0305 – 0.0000] + [1.0000 – 1.0411] x), Protein C (y = [-2.2598 – 1.1058] + [0.9843 – 1.0217] x) and D-dimer (y = [-0.0249 – 0.0175] + [0.9688 – 1.0235] x). Passing-Bablok regression analysis for fibrinogen showed systematic and proportional differences (y = [0.0087 – 0.0997] + [0.9547 – 0.9935] x). Conclussion We have concluded that cap-piercing technology is acceptable for routine coagulation testing on Sysmex® CS-2500 System.
