Laboratory diagnosis of Ebola and Marburg hemorrhagic fever.

The control of Filovirus outbreaks can be greatly enhanced by timely laboratory confirmation of infection or the identification of alternative disease processes. The status of current laboratory diagnostics for Ebola and Marburg virus infections is discussed in terms of the assays available and their interpretation. In addition, the role of field-based laboratory support and its limitations and capabilities in an outbreak response setting, especially in regards to real-time PCR and immunofiltration assays, is presented.
