Our Process

Submitting a sample for testing is a simple process, and we’re here to guide you every step of the way.

Consult with Our Team (Recommended First Step)
Before sending a sample, we encourage you to discuss your needs with one of our pathologists. This helps ensure the correct sampling approach and the most effective diagnostic methods for your crop. If needed, we can provide guidance on proper sampling techniques.

Prepare & Ship Your Sample
We accept both symptomatic and asymptomatic plant tissue and hold the necessary permits for sample shipments. If you’re unsure about the best way to send your sample, our team can assist in ensuring proper packaging and compliance with shipping regulations.

Laboratory Testing & Analysis
Once your sample arrives, we apply the appropriate analytical methods based on:

  • The crop type
  • What we know about the sample and common pathogens associated with it
  • The most suitable diagnostic techniques

For crops like grapevines and strawberries, we offer MultiScan, a specialized test panel that screens for commonly found pathogens in these crops.

Receive Your Results & Next Steps
You’ll be notified when your sample is received and when results are available. If further consultation is needed, our team is happy to help interpret the findings and discuss any necessary next steps.
