与酶联免疫吸附试验和核酸扩增试验相比,诊断电子显微镜有两个优点。经过简单快速的阴性染色准备后,电子显微镜的无定向“开放视野”可以对样本中所含的不同物质进行快速形态学识别和鉴别诊断。给出了有效样品收集、制备和颗粒富集的详细信息。讨论了诊断电子显微镜在临床或流行病学危急情况以及生物恐怖事件中的应用。电子显微镜可应用于许多身体样本,还可以加速常规细胞培养诊断。为了充分发挥诊断电子显微镜的潜力,应该对其进行质量控制,将其作为一线方法应用,并与其他诊断技术协调和并行运行。
Diagnostic electron microscopy has two advantages over enzyme-linked immunosorbent assay and nucleic acid amplification tests. After a simple and fast negative stain preparation, the undirected, “open view” of electron microscopy allows rapid morphologic identification and differential diagnosis of different agents contained in the specimen. Details for efficient sample collection, preparation, and particle enrichment are given. Applications of diagnostic electron microscopy in clinically or epidemiologically critical situations as well as in bioterrorist events are discussed. Electron microscopy can be applied to many body samples and can also hasten routine cell culture diagnosis. To exploit the potential of diagnostic electron microscopy fully, it should be quality controlled, applied as a frontline method, and be coordinated and run in parallel with other diagnostic techniques.
