The OpenTHC Laboratory Information Management System (LIMS) is an open-source, web-based quality assurance platform engineered specifically for the licensed cannabis industry. Designed for transparency, and precision, it empowers analytical laboratories, growers, and processors to track samples, validate test results, and generate secure certificates.

Unlike proprietary, closed-source LIMS products, the OpenTHC lab modules are community-driven and built on open standards. Originally developed as a standalone component, the LIMS features have been fully integrated into the core OpenTHC Seed to Sale Platform (ERP).

Laboratories have the freedom to host the software internally or opt for a managed solution.

Key Capabilities

Sample Management & Intake

• Chain of Custody Tracking: Log physical sample collections, photograph specimens, generate internal barcoded labels, and track handoffs.
• Grower & Processor Integrations: Let growers securely generate sample records in their profiles and share immediate test tracking links directly with your lab.
• Traceability Synchronization: Seamlessly pull samples from and push verified QA test results back to state-mandated networks.

Results Recording & Validation

• QA Limits Validation: Systematically flag samples that exceed regulatory tolerance levels for pesticides, heavy metals, microbial contaminants, mycotoxins, and moisture.
• Potency & Terpene Profiling: Record precise cannabinoid and terpene breakdowns via direct manual input or batch spreadsheet uploads.
• Official COA Certificates: Generate, stamp, lock, and publish official PDF Certificate of Analysis (COA) records.

Open API & Interoperability

• Simple Three-Step API: Integrates with third-party software to (1) Create Lab Sample, (2) Update Lab Sample, and (3) Query/Search Lab Result Data.
• OAuth2 Authentication: Third-party developers can query authorized lab results using standard secure tokens.

Technical Architecture

The OpenTHC LIMS / Lab module is built upon the OpenTHC Common web application architecture:

• Backend Engine: PHP / Slim Framework

• Database Layer: PostgreSQL

• Caching & Session Storage: Redis

• Frontend: Bootstrap 5, SASS, and jQuery

• Project Home: OpenTHC Seed to Sale Platform (/app)
  The laboratory systems have been migrated and are actively maintained within the main ERP and Track & Trace software application.

• Self-Hosted Deployment: openthc/docker on GitHub
  Contains container orchestration templates, service dependencies, and configuration defaults for launching a self-hosted environment locally.

Support Open Source Software

Commercial cannabis operations demand high reliability, secure data isolation, automated backups, and 24/7 uptime.

If you prefer not to manage your own servers, databases, and compliance APIs, we offer a fully managed cloud-hosted instance of the application.
