Tropical Diseases
Point-of-care rapid testing for tropical diseases. OEM/ODM manufacturer.
Overview
Tropical and neglected diseases include chikungunya, Zika, leptospirosis, leishmaniasis, Chagas, filariasis, typhoid, cholera and tuberculosis.
Diagnostic Markers & Methods
IgM/IgG serology · antigen tests (cholera O1/O139, typhoid Ag) · combined panels.
Testing Window
Varies by pathogen; serology typically detects antibodies 1–2+ weeks after onset.
Interpretation
Serology cross-reactivity is common among tropical pathogens; results require epidemiological context and confirmation where available.
Confirmatory Testing
PCR, culture, or paired serology depending on the pathogen.
The Author's Take
Position: In tropical serology, lead with the cross-reactivity caveat — buyers who understand flavivirus overlap are buyers who don't return product.
- Dengue/Zika/chikungunya serology cross-reacts; interpretation needs epidemiological context.
- Field programs value room-temperature stability and instrument-free formats above all.
- Bulk/tender supply with full documentation is where the margin is.

Frequently Asked Questions
Do dengue, Zika and chikungunya tests cross-react?
Yes — they are related viruses and serology can cross-react, so results must be interpreted with travel and epidemiological context.
Do tropical rapid tests need cold chain?
No — colloidal-gold lateral-flow tests are room-temperature stable, a key advantage for remote and tropical distribution.
What documentation do tender programs need?
CE/ISO certificates, validation data, COA, stability data and export documentation — request the full dossier before bidding.
