Hardy Diagnostics

What Hardy Diagnostics does

Hardy Diagnostics is a 46-year-old, 100% employee-owned US manufacturer and distributor of microbiological products headquartered in Santa Maria, California. The company manufactures over 2,700 products in-house — spanning prepared and dehydrated culture media (CRITERION, HardyCHROM chromogenic media, CompactDry ready-to-use plates), rapid diagnostic lateral flow assays (the NG-TEST portfolio distributed from NG Biotech), antimicrobial susceptibility disks (HardyDisks, MASTDISCS), environmental monitoring instruments (TRIO.BAS air samplers, EnSURE ATP systems), specimen collection systems (HealthLink, TransPRO VTM), and adjunct laboratory equipment — and distributes over 13,000 laboratory products in total. It operates as an FDA-licensed in vitro medical device manufacturer under ISO 13485 and ISO 17025 certifications, with products supporting USP <60>-<800> compliance, AOAC/MicroVal/NordValid approvals, and FDA Breakthrough Device Designations for NG-TEST Candida auris and Acineto-5.

The company serves five primary end-markets: clinical diagnostics (hospitals, reference labs, physician offices), pharmaceutical and compounding pharmacy microbiology (sterility, environmental monitoring, USP compliance), food and beverage safety testing, cannabis quality assurance, and cosmetics testing. Revenue is generated through catalog unit-pricing on a transactional e-commerce storefront, direct enterprise sales supported by a dedicated sales representative network, GSA Advantage government procurement contracts, custom product development and contract manufacturing, and exclusive US distribution arrangements for partner brands (NG Biotech, NEMIS Technologies, Gradientech, Hygiena, Microbiologics, Sartorius).

Distribution is conducted through 10 US distribution centers enabling next-day delivery, with no disclosed international manufacturing footprint. The founder Jay Hardy retired as President and CEO in October 2025 after 45+ years and was succeeded by Christopher Catani. Named enterprise customers include Pepsi, Procter &amp; Gamble, and Thermo Fisher Scientific.

Partnerships

Six partnerships are on record, tiered core and minor.

• NG BiotechcoreStrategic or Co-development Partner · 18 February 2026Hardy Diagnostics partnered with NG Biotech to develop and distribute rapid diagnostic assays NG-TEST Candida auris and NG-TEST Acineto-5. These tests received FDA Breakthrough Device Designation targeting critical drug-resistant pathogens identified by WHO. The assays deliver results in 15 minutes using lateral flow immunoassay technology without requiring PCR or specialized equipment. Hardy Diagnostics serves as the exclusive US distributor for these tests, which are currently available for Research Use Only while FDA review continues. The Candida auris test is the first rapid lateral flow immunoassay specifically designed to identify that multidrug-resistant yeast.
• NEMIS TechnologiescoreChannel Partner/ Reseller/ Distributor · 19 December 2025Hardy Diagnostics entered a strategic partnership with Swiss-based NEMIS Technologies to exclusively distribute NEMIS N-Light rapid on-site pathogen detection technology in North America. The chemiluminescence-based system enables food manufacturers and environmental testing teams to conduct rapid pathogen detection directly on-site for improved contamination control. The partnership includes educational initiatives through NEMIS Academy aimed at transforming food safety standards across the region. NEMIS's technology is already trusted by major European food producers.
• GradientechminorChannel Partner/ Reseller/ Distributor · 19 February 2025Hardy Diagnostics serves as the exclusive US distribution partner for Gradientech's QuickMIC diagnostic system, which provides rapid antimicrobial susceptibility testing results within 2-4 hours. The system is currently CE marked and used in European hospitals. Gradientech submitted its 510(k) premarket notification to the FDA in late 2025, and FDA clearance would enable Hardy Diagnostics to commercialize the QuickMIC system in the United States.
• MicrobiologicsminorChannel Partner/ Reseller/ DistributorHardy Diagnostics distributes Microbiologics quality control organisms and molecular controls for use in microbiology laboratories. The partnership provides access to QC microorganisms and reference organisms for laboratory validation and testing procedures.
• HygienaminorChannel Partner/ Reseller/ DistributorHardy Diagnostics distributes Hygiena ATP monitoring systems including EnSURE luminometers and UltraSnap ATP tests for surface hygiene verification in food safety and environmental monitoring applications.
• SartoriusminorChannel Partner/ Reseller/ DistributorHardy Diagnostics distributes Sartorius Sterisart sterility testing systems including membrane filtration equipment for pharmaceutical quality control and USP 71 sterility testing compliance.
