Diagnostics Device Manufacturing & Assembly
End-to-end manufacturing for diagnostic devices, reagents, and consumables. DFM, cartridge assembly, reagent packaging, and sterilization under one FDA-registered, ISO 13485 quality system.


End-to-end manufacturing for diagnostic devices, reagents, and consumables with FDA-registered, ISO 13485-certified cleanroom services.
End-to-End Solutions for Diagnostic Device Development
Bringing diagnostic devices and consumables to market requires precision, regulatory expertise, and scalable manufacturing solutions. At Life Science Outsourcing (LSO), we specialize in designing, assembling, and packaging in-vitro diagnostics (IVD) devices, reagent formulations, and consumable components to help diagnostics companies accelerate commercialization while ensuring compliance with FDA and ISO 13485 standards.
From early-stage design for manufacturing (DFM) to high-volume production and sterile packaging, our comprehensive, in-house solutions support rapid product development and regulatory approval.

Design for Manufacturing (DFM) for Diagnostic Devices
Optimizing your diagnostic device for scalability, cost-efficiency, and regulatory compliance begins with design for manufacturing (DFM). LSO provides:
- Material selection and component integration support
- DFM analysis to streamline production and reduce costs
- Risk mitigation strategies for regulatory approval

Why LSO?
LSO's diagnostics capabilities were purpose-built through the January 2023 acquisition of J-Pac Medical — bringing precision reagent packaging, microfluidic cartridge assembly, and diagnostics-specific DFM expertise under LSO's FDA-registered, ISO 13485 certified quality system.
For diagnostics manufacturers, this means a single partner for the complete manufacturing workflow: DFM review, reagent handling, cartridge assembly, validated packaging, sterilization, labeling, and fulfillment. No inter-vendor handoffs. No quality system gaps. One partner from pilot to millions of units.
With 12 cleanrooms (Class 5–8), controlled-environment manufacturing across three facilities, and 25+ years of regulated manufacturing experience, LSO has the infrastructure and expertise to scale your diagnostics consumables without compromising the precision that your assay demands.
