Arbovirus Testing Services
Arboviruses (Arthropod-borne viruses) are a diverse group of viruses transmitted to humans and animals through the bites of blood-sucking arthropods, such as mosquitoes, ticks, and sandflies. This extensive viral family includes pathogens responsible for major global public health crises, including Dengue, Zika, West Nile, Japanese Encephalitis Virus (JEV), and various Equine Encephalitis Viruses.
The clinical manifestations of arboviral infections vary widely, ranging from mild fever and rashes to severe hemorrhagic fevers, and even life-threatening neurological invasions (such as viral encephalitis or meningitis). Because different arboviruses often overlap geographically and some exhibit antigenic cross-reactivity, precise laboratory etiological identification is especially critical. Through rigorous serological antibody screening, we can effectively track viral infection trajectories, providing key data for the research and control of arthropod-borne infectious diseases.
Examples of Common and Important Arboviruses:
| Representative Virus | Primary Vector | Common Clinical Manifestations & Disease Features |
| Dengue Virus | Mosquitoes (primarily Aedes) | High fever, severe joint/bone pain, Dengue Hemorrhagic Fever |
| Zika Virus | Mosquitoes (primarily Aedes) | Fever, rash, neonatal microcephaly |
| West Nile Virus | Mosquitoes (primarily Culex) | Fever, viral encephalitis, meningitis |
| Japanese Encephalitis Virus (JEV) | Mosquitoes (primarily Culex) | Acute CNS infection, severe encephalitis |
| Chikungunya Virus | Mosquitoes (primarily Aedes) | Extreme joint pain, fever, rash |
| Eastern/Western Equine Encephalitis Virus (EEEV/WEEV) | Mosquitoes | High fever, headache, severe viral encephalitis |
| Rift Valley Fever Virus | Mosquitoes, Sandflies | Fever, hemorrhagic fever, retinopathy |
| Severe Fever with Thrombocytopenia Syndrome Virus (SFTSV) | Ticks | High fever, thrombocytopenia, multi-organ failure |
Our Services
Relying on our mature immunological platforms, Creative Diagnostics provides in-depth arbovirus serological analysis for research and testing projects. Our core testing portfolio includes:
- Arbovirus IgG/IgM Antibody Panels:
- IgM Antibody Detection: IgM is typically produced rapidly within days of a viral infection, serving as a key marker for identifying acute or recent infections.
- IgG Antibody Detection: IgG appears slightly later but persists for a very long time. Detecting IgG helps assess past infection history and immune status. Furthermore, observing titer changes (elevation or seroconversion) in paired samples assists in confirming recent infections.
- Panel Advantages: Panel-based testing allows for the simultaneous screening of specific antibodies against multiple common arboviruses in a single assay, greatly enhancing screening efficiency.
- Indirect Immunofluorescence Assay (IFA):
All antibody panels utilize Indirect Immunofluorescence Assays (IFA). As a classic viral serology technique, IFA allows for the direct observation of specific fluorescence emitted by antigen-antibody complexes under a fluorescence microscope. It not only offers extremely high sensitivity but also provides intuitive morphological verification, effectively distinguishing non-specific background signals. - In-Depth Cerebrospinal Fluid (CSF) Analysis:
For neurotropic arboviruses (such as West Nile Virus or JEV), routine blood tests often fail to reflect the true infection status of the central nervous system. We possess the specialized capabilities to process and analyze CSF samples. By detecting specific IgM in CSF or calculating the CSF/serum antibody index, we provide the most direct evidence of localized infection for research into viral encephalitis or meningoencephalitis.
Our Advantages
- Dual Sample Compatibility: We feature robust sample pretreatment and matrix optimization capabilities, seamlessly accommodating serum, plasma, and the more complex, scarce CSF samples.
- Intuitive and Reliable IFA Platform: IFA combines immunological specificity with high microscopic resolution. Fluorescence is interpreted by experienced technical experts, minimizing false-positive cross-reactivity between closely related viruses, such as those within the Flavivirus genus.
- Comprehensive Infection Phase Assessment: The combined application of IgG and IgM panels accurately outlines whether a subject is in the acute infection, convalescent, or past exposure phase, providing a complete time-dimensional data profile.
In an era where arboviral infectious diseases are frequent and climate change is expanding their transmission range, accurate and timely etiological identification is the cornerstone of scientific prevention and medical research. We look forward to being your trusted research and testing partner with our exceptional analytical platforms and rigorous data.
