Summary
Accurate serological tests for emerging arboviruses like Zika are crucial but face challenges. Understanding test limitations, patient history, and timing is essential for reliable diagnosis.
Area of Science:
- * Virology and immunology
- * Diagnostic assay development
- * Public health surveillance
Background:
- * Emerging arboviruses, including Zika, dengue, and chikungunya, pose significant global health risks.
- * Laboratory diagnostics, encompassing molecular, antigen, and antibody tests, are vital for patient management and disease control.
- * Serological tests are critical for detecting past or present arbovirus infections.
Purpose of the Study:
- * To provide an overview of the challenges associated with serological testing for major emerging arboviruses.
- * To analyze the performance of commercially available antibody- and antigen-detecting tests.
- * To discuss factors influencing the accuracy and reliability of arbovirus serological diagnostics.
Main Methods:
- * Systematic literature research in PubMed, retrieving data from 89 peer-reviewed articles.
- * Analysis of performance data for commercially available antibody- and antigen-detecting tests.
- * Identification of commonly used diagnostic tests and their performance characteristics.
Main Results:
- * Serological test performance is significantly impacted by the timing of sample collection and the use of paired acute and convalescent samples.
- * Patient infection history, including prior arbovirus exposure ('original antigenic sin') and cross-reactivity with other pathogens, can lead to inaccurate results.
- * Rapid point-of-care tests exhibit lower sensitivity compared to laboratory-based assays like ELISA, with performance varying between endemic and non-endemic regions.
Conclusions:
- * Awareness of inherent test limitations is crucial for reliable serological diagnostics.
- * Multiplexed testing and convalescent sample analysis can enhance diagnostic performance.
- * The global spread of arboviruses necessitates careful implementation and evaluation of serological tests, as unambiguous results may not always be achievable.
