Virosensor -Based Real-time Diagnosis of Enterovirus 71 and Influenza Virus
Recruitment status was: Recruiting
|Study Design:||Intervention Model: Single Group Assignment
Masking: Double Blind (Investigator, Outcomes Assessor)
Primary Purpose: Diagnostic
|Official Title:||Virosensor -Based Real-time Diagnosis of Enterovirus 71 and Influenza Virus|
- Influenza virus or Enterovirus 71 detection [ Time Frame: 1 Day ]In comparison with results from viral isolation and RT-PCR of influenza virus or Enterovirus 71 , we evaluate the performance of virosensor, including sensitivity, specificity, cross-reaction and reproducibility.

|Estimated Primary Completion Date:||October 2015 (Final data collection date for primary outcome measure)|
virosensor, which was developed for the rapid and sensitive detection of viral antigen in medical samples, will be used for analyzing the interaction kinetics between anti-influenza-virus (or anti-EV71-virus) and its influenza virus antigen (or EV71 antigen) present in patients and normal samples.
The system incorporates the use of chip formats. In antibody probing, antibodies are bound as a suitable probe, which specifically and selectively binds targeted molecules (virus antigen) in the test specimens.
- Sample acquirement： At National Taiwan University Hospital in Taiwan, we will enroll patients who have influenza-like illness or enterovirus infection . We will take three throat swabs for each patient: one for viral isolation, one for RT-PCR and the last for the Virosensor - based real-time diagnosis.
- Virosensor diagnosis： Virosensor (structural chip-based optosensing virus probing system), which is for the rapid and sensitive detection of viral antigen in medical samples, will be used for analyzing the interaction kinetics between anti-influenza-virus (or anti-Enterovirus 71-virus) and its influenza virus antigen (or Enterovirus 71 antigen) present in patients'and normal samples.
- Gold standard： viral isolation and RT-PCR
