Laboratory Diagnosis of Dengue Infection: Current Techniques and Future Strategies
TLDR
The pros and cons of currently available methods for identification of dengue virus infection, ranging from conventional to sophisticated tests are considered, highlighting the necessity for standardisation and quality control.Abstract:
Dengue is an increasingly significant vector-borne infectious disease, with over 50 million cases reported in more than half the world’s recognised independent states. Dengue fever, dengue haemorrhagic fever and dengue shock syndrome are distinct clinical forms of an infection that is caused by Dengue Virus, a member of the Flaviviridae family. All four well characterized serotypes of the virus can cause the full spectrum of disease from asymptomatic infection to life-threatening symptoms. For effective prevention and/or treatment of disease symptoms, early and rapid detection of virus in specimens collected from clinically suspected persons is a requirement that remains challenging. A positive laboratory diagnosis is essential to confirm dengue virus infection and hence to inform patient therapy. Here, we consider the pros and cons of currently available methods for identification, ranging from conventional to sophisticated tests. Reports indicate the use of a variety of diagnostic methods of varying sensitivity, highlighting the necessity for standardisation and quality control. Several novel approaches are in development and demand further evaluation.read more

TL;DR: A new technique for the detection, classification and antibody screening of DENV based on electrochemical impedance spectroscopy (EIS) is presented, which found that the charge transfer resistance of a gold electrode coated with graphene oxide reinforced polymer was influenced by virus type and quantity exposed on the surface.

Electrochemical Immunosensor Based on Antibody- Nanoparticle Hybrid for Specific Detection of the Dengue Virus NS1 Biomarker.
TL;DR: In this article, a sensitive, specific, and label-free electrochemical immunosensor was developed for the direct detection of the unstructured protein NS1, which was designed with a biosensing surface consisting of antifouling moieties and biorecognition molecules.

Electrochemical Immunosensor Based on Antibody-Nanoparticle Hybrid for Specific Detection of the Dengue Virus NS1 Biomarker
TL;DR: The developed immunosensor was able to detect the NS1 antigen in actual serum specimens from patients infected with Dengue virus and did not cross-react with human sera infected with malaria parasites.
