Blood Collection Tube Manufacturing in the UK
Blood collection tube manufacturing involves moulding a sterile tube body, coating it with an additive (EDTA, heparin, or clot activator), assembling a vacuum-sealed stopper, sterilizing it (gamma or ETO), and quality-testing it — all under an ISO 13485 QMS. In the UK, finished tubes must also carry UKCA marking and be registered with the MHRA as In Vitro Diagnostic (IVD) medical devices before sale.
What Are Blood Collection Tubes?
Blood collection tubes are sterile containers used to collect, store, and transport blood samples for diagnostic testing in hospitals and laboratories. Each tube is pre-filled with an additive — such as an anticoagulant or clot activator — to preserve sample integrity until testing.

Common types of blood collection tubes include:
- Vacuum blood collection tubes
- Non-vacuum (manual) tubes
- Serum separator tubes
- EDTA tubes
- Heparin tubes
- Fluoride/oxalate tubes
Why Start Blood Collection Tube Manufacturing in the UK?
The UK has growing demand for high-quality diagnostic consumables, driven by an expanding network of healthcare facilities, pathology labs, and rising interest in self-diagnostic testing.
Key growth drivers:
- Rising demand for in-vitro diagnostics (IVD)
- Government initiatives to strengthen domestic manufacturing
- Export opportunities within the EU and global markets
- Rising healthcare spending and laboratory automation
For manufacturers entering this space, blood collection tube manufacturing offers a steady, scalable business opportunity with long-term growth potential.
Step-by-Step Blood Collection Tube Manufacturing Process
1. Raw Material Selection
The core components of a blood collection tube are:
- Tube body — usually PET or glass
- Cap — medical-grade polyethylene or polypropylene
- Rubber stopper — for vacuum sealing
- Additives — EDTA, heparin, or clot activators
Using medical-grade materials is essential for product safety, durability, and regulatory approval.
2. Tube Moulding
Tube bodies are formed using injection moulding or blow moulding machines to precise dimensions, ensuring uniform wall thickness and high transparency for easy sample visibility.
3. Additive Coating
Each tube type requires a specific internal additive coating:
- EDTA tubes — for complete blood count (CBC) tests
- Heparin tubes — prevent clotting for plasma separation
- Clot activator tubes — accelerate clotting for serum analysis
Automated additive dispensing and drying systems ensure consistent, accurate coating.
4. Stopper and Cap Assembly
Rubber stoppers are inserted and sealed to maintain the vacuum. For vacuum tubes, specialized sealing machines create the negative pressure that automatically draws blood in when the tube is punctured.
5. Labeling and Printing
Each tube is labeled with its type, additive used, expiry date, and batch number. Modern lines use automated labeling machines with barcode integration to support traceability and digital recordkeeping.
6. Sterilization
Sterilization ensures the safety of the finished medical device. The two most common methods are:
- Gamma radiation
- Ethylene oxide (ETO) sterilization
Sterilization parameters must comply with ISO 11135 (ETO) and ISO 11137 (gamma) standards.
7. Quality Control and Testing
Every batch must pass strict testing before release:
- Vacuum retention test
- Additive effectiveness test
- Leakage test
- Sterility and biocompatibility tests
Quality assurance is managed under a Quality Management System (QMS) certified to ISO 13485.
8. Packaging and Storage
Sterilized tubes are packed into blister packs or cartons under controlled conditions, preserving sterility until point of use.
Machinery Required for Blood Collection Tube Manufacturing
A complete production setup typically includes:
| Machinery | Function |
|---|---|
| Tube forming/moulding machines | Shape the tube body to precise dimensions |
| Additive coating machines | Apply and dry internal additives |
| Vacuum sealing systems | Create negative pressure inside sealed tubes |
| Cap and stopper assembly line | Fit and seal rubber stoppers and caps |
| Labeling and printing machines | Apply batch, expiry, and barcode data |
| ETO/Gamma sterilizers | Sterilize finished tubes |
| Packaging equipment | Pack tubes while preserving sterility |
Automating these stages improves consistency, reduces contamination risk, and supports high-volume output.
Regulatory Requirements for Blood Collection Tube Manufacturing in the UK
In the UK, blood collection tubes are classified as In Vitro Diagnostic (IVD) medical devices. Manufacturers must comply with the following regulations:
- UKCA Marking (post-Brexit requirement)
- Ensures your product meets UK Medical Device Regulations 2002 (as amended).
- MHRA Registration
- All manufacturers and importers must register their IVD devices with the Medicines and Healthcare products Regulatory Agency (MHRA).
- Quality Management System (ISO 13485)
- A certified QMS is required for regulatory approval and consistent manufacturing quality.
- Technical Documentation
- Includes product description, risk analysis, test reports, and sterilization validation.
- Performance Evaluation and Clinical Evidence
- Required to demonstrate device reliability and safety.

FAQ
What are the regulatory requirements for manufacturing blood collection tubes in the UK?
Manufacturers must comply with the UK Medical Devices Regulations 2002 (as amended), implement an ISO 13485-compliant Quality Management System (QMS), apply ISO 14971 risk management, prepare technical documentation, and complete the applicable UKCA conformity assessment where required. Eligible devices must also be registered with the MHRA before being placed on the Great Britain market.
Which international standards apply to blood collection tube manufacturing?
Manufacturers commonly implement ISO 13485 for quality management systems and ISO 14971 for risk management. Blood collection tubes are generally designed and evaluated in accordance with ISO 6710, which specifies requirements for single-use containers for venous blood specimen collection. Additional standards for sterilization, packaging, labeling, and biocompatibility may also apply depending on the product type.
Are blood collection tubes regulated as IVD medical devices in the UK?
Blood collection tubes may be regulated as in vitro diagnostic (IVD) medical devices or as accessories to IVD medical devices, depending on their intended purpose and regulatory classification. Manufacturers should determine the correct classification, prepare the required technical documentation, and comply with the applicable UK regulatory requirements before placing the product on the market.
What documents are required for UKCA marking and MHRA registration?
Manufacturers typically prepare technical documentation, ISO 13485 certification, ISO 14971 risk management files, ISO 6710 compliance evidence where applicable, performance evaluation data, sterilization validation reports (for sterile products), labeling, Instructions for Use (IFU), post-market surveillance documentation, and a Declaration of Conformity. Eligible devices must also be registered with the MHRA.
