About us

Proven reliability and instant peace of mind

The Pocket Diagnostic in-field test kits were originally developed for the UK government plant health inspectors in 1999 for potato and tomato viruses.  Since then, the product range has grown and the tests have become popular with growers, farmers, agronomists, research institutes and private laboratories. 

All demanding high quality and reliability, our clients continue to use Pocket Diagnostic kits as part of their routine disease monitoring programmes or as a direct reaction to potentially devastating disease outbreaks.

The kits are developed and manufactured by Forsite Diagnostics in York, UK, using state-of-the-art equipment in controlled environment production facilities.  The tests are validated comprehensively and show over 96% correlation with laboratory diagnostic methods.

Forsite’s active R&D programmes continue to generate new and improved tests in response to customer demands and new and important disease outbreaks.  This makes Pocket Diagnostic the first choice for in-field plant diagnosis.
