Comprehensive Typhoid detection made accessible
Typhoid fever and Paratyphoid fever are caused by bacterial infections by Salmonella enterica Typhi and Paratyphi types A, B, and C, respectively, which are transmitted through the ingestion of tainted food and water. World-wide, an estimated 17 million cases and 600,000 associated deaths occur annually. The clinical diagnosis of infections traditionally depends on blood culture or the Widal test, but these tests can be challenging to use in resource-limited areas where infections are most common.
OnSite® Typhoid Rapid Tests are trusted in more than 80 countries to give clinicians simple and reliable tools to detect and differentiate S. typhi and S. paratyphi infections, aiding quality point-of-care patient management in the communities that need it most.
Why OnSite®?
- Simple and rapid tests simultaneously detect key S. typhi and Paratyphi analytes, aiding in the determination of current or previous exposure, or in guiding patient care decisions by differentiating between two similar diseases with different treatment requirements.
- Not bound by the resource and environmental limitations of traditional Typhoid diagnostic aids, OnSite® Typhoid Rapid Tests deliver laboratory-quality precision and suitability for use at the point-of-care.
