Start a clinical laboratory service
How to set up and operate a clinical laboratory in the UK. Covers UKAS accreditation, CQC registration, HTA licensing, MHRA requirements, professional registration, and quality standards for medical testing services.
Clinical laboratories provide medical testing services that support diagnosis, treatment, and monitoring of patients. Setting up a laboratory requires multiple regulatory approvals, quality accreditation, and compliance with strict standards.
The regulatory framework is complex and layered. You'll typically need UKAS accreditation for quality standards, CQC registration if you're providing diagnostic services in England, and potentially HTA licensing if you're working with human tissue. The specific requirements depend on the type of testing you'll perform.
Timeline: Expect 12-18 months from planning to operational status. UKAS accreditation alone takes 12-18 months, and you must have this before providing NHS services or tendering for contracts.
UKAS accreditation - the quality foundation
UKAS (United Kingdom Accreditation Service) accreditation to ISO 15189 is the quality standard for medical laboratories. It's mandatory for NHS laboratories and strongly recommended for private laboratories. Without it, you cannot tender for NHS contracts.
ISO 15189 covers both quality management (like ISO 9001) and technical competence. It's specific to medical laboratories and more demanding than general laboratory standards.
Choosing your laboratory scope
You must define which clinical disciplines you'll cover. Each discipline may require additional assessment days and costs. Starting with a narrow scope and expanding later is often more practical than seeking full multi-discipline accreditation from the outset.
Preparing for UKAS assessment
Before you apply, you need:
- A complete Quality Management System (QMS) with documented procedures
- Validated testing methods with performance data
- Internal quality control (IQC) running for at least 3 months
- External quality assessment (EQAS) participation
- Staff competency assessments completed
- Equipment validation and calibration records
- At least 6 months of operational data demonstrating you meet the standard
Many laboratories fail their first assessment due to insufficient preparation. Consider hiring a consultant with ISO 15189 experience for gap analysis.
Which quality standard do you need?
Different laboratory types require different ISO standards:
CQC registration for diagnostic services (England)
If you're providing diagnostic and screening procedures in England, you must register with the Care Quality Commission (CQC). This applies to pathology laboratories, imaging centres, and screening services that directly provide services to patients.
Do you need to register? You need CQC registration if:
- Patients attend your facility for sample collection or testing
- You provide diagnostic reports directly to patients
- You operate imaging equipment (X-ray, MRI, CT, ultrasound)
You may not need registration if you're purely a reference laboratory processing samples from other healthcare providers without direct patient contact.
CQC fundamental standards for laboratories
Registered laboratories must meet CQC's fundamental standards, including:
- Safe care and treatment - Risk assessments for hazardous materials, infection control
- Safeguarding - Policies for vulnerable adults and children
- Staffing - Sufficient numbers of qualified staff
- Fit and proper persons - DBS checks, professional registration verification
- Good governance - Quality monitoring, incident reporting, duty of candour
CQC inspections assess laboratories against these standards and publish ratings (Outstanding, Good, Requires Improvement, or Inadequate).
Human Tissue Authority licensing
If your laboratory works with human tissue for research, post-mortem examination, or transplantation, you need a licence from the Human Tissue Authority (HTA).
When you need HTA licensing:
- Storing human tissue for research purposes
- Performing post-mortem examinations
- Processing tissue for transplantation or assisted conception
- Storing organs or tissue for anatomical examination
Routine diagnostic testing on samples (blood tests, biopsies sent for diagnosis) does not require HTA licensing. The licensing requirement applies to storage and use beyond diagnosis.
Appointing a Designated Individual
Every HTA licensed establishment must have a Designated Individual (DI) - the person legally accountable for the licensed activities. The DI must:
- Be suitably qualified (usually medical or scientific degree)
- Have sufficient authority within the organisation
- Not have been disqualified by HTA
- Complete HTA training on the Human Tissue Act
The DI cannot delegate this accountability, though day-to-day management can be performed by others.
Blood transfusion and MHRA authorisation
If you're operating a hospital blood bank or blood establishment, you need MHRA authorisation in addition to UKAS accreditation.
Blood traceability requirements
Blood establishments must maintain complete traceability from donor to recipient and vice versa for 30 years. This means:
- Electronic systems capable of tracking every unit
- Archive systems for 30-year data retention
- Procedures for "look-back" when donor issues are identified
- Haemovigilance reporting to SHOT (Serious Hazards of Transfusion)
This is one of the most demanding record-keeping requirements in healthcare.
Genetic testing services
Genetic testing has additional regulatory requirements due to the sensitive nature of genetic data and the implications for patients and their families.
When genetic counselling is required
For medical-grade genetic tests offered directly to consumers, you must provide access to genetic counselling. This includes:
- Pre-test counselling about what the test can and cannot tell them
- Post-test counselling to explain results
- Referral pathways to clinical genetics services for abnormal results
Recreational ancestry tests don't require counselling, but any test marketed for health purposes does.
Point of care testing (POCT) governance
If you're providing oversight for near-patient testing (tests performed outside the laboratory, such as ward-based glucose testing or GP surgery INR monitoring), you need robust governance frameworks.
Managing POCT across multiple sites
As the governing laboratory, you're responsible for:
- Approving which devices can be used
- Training and authorising all operators
- Providing and monitoring quality control
- Auditing compliance at POCT sites
- Ensuring results are correctly recorded in patient records
POCT is often underestimated in complexity. A single laboratory might govern hundreds of devices across dozens of sites.
Workforce and professional registration
Clinical laboratories must employ appropriately qualified and registered professionals. Registration is a legal requirement for certain roles.
Building your laboratory team
Minimum staffing for a small laboratory:
- Laboratory Director - Consultant pathologist (GMC registered) or senior clinical scientist (HCPC registered)
- Quality Manager - Experienced biomedical scientist with QMS knowledge
- Biomedical Scientists - HCPC registered, minimum 2 FTE for 24/5 operation
- Medical Laboratory Assistants - Non-registered support staff for sample processing
Consultant pathologist oversight is essential for histopathology and some microbiology services. For clinical biochemistry and haematology, a clinical scientist can provide clinical leadership.
NHS pathology network requirements
If you're tendering for NHS pathology contracts, you must meet additional requirements:
- UKAS ISO 15189 accreditation - Mandatory, no exceptions
- Network participation - Engagement with local pathology networks
- Digital connectivity - Integration with NHS IT systems (ICE, LIMS)
- Turnaround times - Ability to meet NHS contract SLAs
- 24/7 emergency capability - For acute hospital contracts
- Consultant cover - GMC-registered consultant pathologist provision
NHS tenders are highly competitive and favour larger laboratories or consortia due to scale requirements.
Laboratory equipment and IVD devices
All laboratory equipment and In Vitro Diagnostic (IVD) devices must be:
- CE or UKCA marked - Depending on when placed on market and where used
- Validated - Performance verified against manufacturer's claims
- Calibrated - Regular calibration with traceability to reference standards
- Maintained - Preventative maintenance schedules followed
Keep validation records, calibration certificates, and maintenance logs - UKAS will inspect these during assessment.
Information governance and data protection
Clinical laboratories handle sensitive patient data and must comply with:
- UK GDPR - Data protection for patient information
- NHS Data Security and Protection Toolkit - For NHS contractors
- Caldicott Principles - NHS information governance standards
- ISO 27001 (optional) - Information security management
Genetic data is "special category data" under UK GDPR and requires additional safeguards, including explicit consent for processing.

Common pitfalls to avoid
Underestimating timescales: Many laboratories assume they can achieve accreditation in 6 months. The reality is 12-18 months minimum. Plan accordingly.
Insufficient QMS documentation: UKAS requires comprehensive documentation. Every process needs an SOP. Budget time for this.
Inadequate validation data: You need months of performance data before UKAS assessment. Don't apply too early.
Wrong staffing mix: You need HCPC-registered biomedical scientists for certain roles. MLAs alone are insufficient.
Ignoring scope creep: Expanding your scope post-accreditation requires additional UKAS assessment and fees. Plan your full scope from the start.
Overlooking HTA: Working with tissue for research? You need HTA licensing. Don't assume diagnostic work exempts you.
