In addition, a secondary objective was to establish specific reference intervals for RtcPLT and to propose an optimal diagnostic model.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>We conducted a descriptive cross\u2010sectional study of 375 subjects, including 84 healthy controls and 291 thrombocytopenic patients. The healthy individuals were utilized to establish the RtcPLT reference range. The patient cohort was classified into PE and BME groups based on the results of bone marrow aspiration and biopsy (BMAB). RtcPLT was measured using the optical fluorescence method on the ADVIA 2120i platform. Diagnostic accuracy was evaluated using receiver operating characteristic (ROC) analysis and Bayesian model averaging (BMA) to propose the optimal model.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      The median RtcPLT in the BME group (2.28%) was significantly lower than that of the PE group (8.27%,\n                      <jats:italic>p<\/jats:italic>\n                      \u00a0&lt;\u00a00.001). The single RtcPLT index (cutoff 4.64%) achieved an area under the curve (AUC) of 0.895 (95% confidence interval [95% CI]: 0.858\u20130.932), showing high sensitivity (90.7%, 95% CI: 81.7%\u201396.2%), specitificity (82.9%, 95% CI: 77.2%\u201387.6%) and negative predictive value (NPV) (NPV: 96.2%, 95% CI: 92.4%\u201398.5%). The optimal model, combining RtcPLT with red blood cells (RBC), neutrophil%, basophil%, retic%, and large unstained cells (LUC%), achieved superior accuracy: AUC value of 0.980 (95% CI: 0.967\u20130.993), sensitivity of 92.0% (95% CI: 83.4%\u201397.0%), and specificity of 94.4% (95% CI: 90.5%\u201397.1%).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>The RtcPLT index measured in this study is a robust, rapid, and automated biomarker for assessing thrombopoietic activity.
