诊断登革出血热病的一个主要的问题是对众多的病人不能作到致病病毒血清型别的鉴定,由于病人继发感染登革病毒而诱发亲缘抗体的交叉反应,致使血清型的诊断产生困难或不可能。因此,病毒分离常是血清型别诊断的唯一方法。然而,从病人血浆或血清中病毒分离率低,近几年来在我们实验室的分离率是介于5%到10%之间。最近研究提示:血液固体成份可以用于病毒分离,已 A major problem in the diagnosis of dengue haemorrhagic fever is the inability to identify the serotypes of the causative virus in a large number of patients and to induce the cross-reactivity of the related antibodies as a result of the patient’s secondary infection with dengue virus, resulting in the diagnosis of serotypes Difficult or impossible. Therefore, virus isolation is often the only way to diagnose serotypes. However, the rate of virus isolation from the patient’s plasma or serum is low and the rate of isolation in our laboratory in recent years is between 5% and 10%. Recent research suggests that blood solids can be used for virus isolation
