研究目的:

本研究的核心意义在于通过验证多重ddPCR技术在血液病血流感染中的诊断价值,推动临床感染防控策略升级。对血液病患者而言,早期识别高危病原体有助于及时调整治疗方案,降低脓毒症、多器官衰竭等并发症风险,同时减少因误诊导致的化疗中断,提升整体生存率。此外,本研究将建立基于ddPCR的标准化检测流程,为拓展其在移植后发热待查等复杂场景的应用提供循证支持,推动分子诊断技术的临床转化与创新。  

Objectives of Study:

The core significance of this study lies in validating the diagnostic value of multiplex droplet digital PCR (ddPCR) in detecting bloodstream infections in patients with hematologic diseases, thereby promoting the advancement of clinical infection control strategies. For hematologic patients, early identification of high-risk pathogens can facilitate timely adjustments to treatment regimens, reduce the risk of complications such as sepsis and multiple organ failure, and minimize chemotherapy interruptions caused by misdiagnosis, ultimately improving overall survival rates. Additionally, this study aims to establish a standardized ddPCR-based detection protocol, providing evidence-based support for its application in complex clinical scenarios such as fever of unknown origin after transplantation. This will further drive the clinical translation and innovation of molecular diagnostic technologies.
