PathogenDx

PathogenDx is a molecular diagnostics company founded in 2014 and based in Scottsdale, Arizona, built around a multiplexed DNA microarray technology called D3 Array. It was created to replace slow, culture-based food-safety testing, which can take multiple days, with a molecular method that food processors can use to catch contamination before product ships.

Its D3 Array platform runs assay panels such as SalSure for Salmonella, EnviroX for Listeria and Salmonella in plant environmental swabs, and SeroX for serotype identification, detecting up to 100 targets in a single reaction with single-gene-copy sensitivity. Results are typically available the same day, versus the multi-day turnaround of standard culture-based methods, and the platform is used by food and poultry processors together with a network of more than 120 partner laboratories across 36 US states.

1. D3 Array platform: multiplexed DNA microarray technology detecting up to 100 targets in a single test reaction.

2. SalSure assay: rapid molecular detection of Salmonella in food and processing environments.

3. EnviroX assay: environmental-swab detection of Listeria and Salmonella validated down to a single colony-forming unit.

4. SeroX assay: serotype identification to support outbreak investigation and root-cause analysis.

5. Same-day results: delivers findings the same day, versus the multi-day turnaround of traditional culture-based testing.

6. Lab network: supported by more than 120 partner laboratories across 36 US states for food and poultry processors.
