What ISO 13485 does
ISO 13485 obliges a manufacturer of medical devices to follow defined processes in a documented and verifiable way. Specifically it governs:
- Design & development — from the requirements document through to design release.
- Production — material and supplier control, in-process checks, batch traceability.
- Risk management — failure modes and their control across the life cycle.
- Market surveillance — vigilance, complaints, corrective and preventive actions (CAPA).
- Continuous improvement — internal audit, management review, defined improvement loops.
This is not a bureaucratic box-ticking exercise — it is the foundation that ensures the 1,000th kit batch delivers the same quality as the first.
Why this matters specifically for test kits
A test kit consists of several components: collection device, tubes, stabiliser solutions, swabs, shipping packaging, instructions. If one of these fails, the whole sample is worthless. Examples:
- A poorly manufactured lancet delivers too little blood — the test is aborted.
- An incorrectly declared stabiliser concentration systematically shifts values.
- Packaging without a temperature buffer lets a sample spoil in a summer letterbox.
- Unclear instructions — the end user makes a small but consequential deviation.
A QMS to ISO 13485 makes the probability of these errors systematically small: suppliers are audited, batches are checked, and complaints lead to documented improvements.
What a QMS means day to day
- Documented processes — who does what, when, and with what evidence.
- Supplier control — components only come from qualified, audited suppliers.
- Batch traceability — every component in every batch is traceable back to the manufacturer.
- CAPA system — complaints and deviations are recorded, analysed and resolved systematically.
- Internal audit — regular self-assessment of process adherence.
- Management review — senior management reviews the system at least annually.
None of this is visible when you hold the finished kit box in your hand. But it is the reason the test can be measured reliably in the laboratory.
ISO 13485 in context
Probatix operates with quality and security standards on three levels:
| Standard | What it covers | Applies to |
|---|---|---|
| ISO 13485 | QMS for medical devices / IVDs | Kit (product) |
| ISO 15189 | QMS for medical laboratories | Laboratory (analysis) |
| ISO 27001 | QMS for information security | Data (platform) |
Together these three create a continuous quality chain: from the kit in the end user’s hands, through laboratory analysis, to the structured result in your system. A gap at any point would undermine the reliability of the entire chain.
Probatix in practice
Probatix operates in conformity with ISO 13485. The scope covers:
- Kit development — requirements definition, design control, validation and verification studies for every kit configuration.
- Design — selection of components (microsampling devices, stabilisers, packaging), layout of instructions and result templates.
- Assembly — putting kits together from qualified individual components, documented batches, visual checks.
- Post-market surveillance — ongoing observation of kit performance after placing on the market.
- Vigilance — structured recording and reporting of incidents in line with IVDR/MDR obligations.
- CAPA — corrective and preventive actions: systematic root-cause analysis for complaints and deviations, with documented measures.
- Complaints management and risk management — documented end-to-end.
What you get as a partner:
- Quality built in — you don’t have to set up your own QMS.
- Audit-ready — when your end customers (insurer, regulator) ask for evidence, we provide it.
- Scalable — multiple branded kits under a single QMS roof, without friction.
