摘要: 隐匿性乙型肝炎病毒感染(OBI)因其极低病毒载量及肝内cccDNA持续潜伏特性,构成全球公共卫生安全的深层挑战。其防控长期受限于传统检测技术的灵敏度瓶颈,亟需通过技术革新实现突破。新兴检测技术在多角度实现突破:液滴数字PCR通过微区室化扩增实现超灵敏定量;CRISPR-Cas系统耦合等温扩增推动即时诊断发展;第三代测序技术开启病毒序列解析新维度;纳米材料介导的信号放大机制重塑基层筛查模式。本文对OBI最新诊断技术发展进行概述,对各个诊断技术的优劣势、输血相关应用前景等进行综合分析并提出建议,为推进我国输血相关OBI风险控制、开发适合我国国情的新检测技术提供科学依据。

Abstract: Occult hepatitis B virus infection (OBI), characterized by extremely low viral loads and the persistent latency of intrahepatic cccDNA, poses a profound challenge to global public health security. Its prevention and control have long been constrained by the sensitivity limitations of conventional diagnostic methods, highlighting the urgent need for technological breakthroughs. Emerging detection technologies are driving progress from multiple perspectives: droplet digital PCR enables ultra-sensitive quantification through micro-compartmentalized amplification; CRISPR-Cas systems coupled with isothermal amplification are advancing the development of point-of-care diagnostics; third-generation sequencing technologies open new dimensions for viral genome analysis; and nanomaterial-mediated signal amplification mechanisms are reshaping screening models at the primary-care level. This review summarizes recent advances in OBI diagnostic technologies, provides a comprehensive analysis of their advantages, limitations, and transfusion-related applications, and offers recommendations to support improved OBI risk control in blood transfusion and the development of novel diagnostic strategies tailored to China's national context.

Key words: Occult hepatitis B virus infection (OBI), Transfusion safety, Blood screening, Ultra-sensitive detection, Droplet digital PCR (ddPCR), CRISPR-Cas
