Roche Point-of-Care-Testing in a Rapidly Shifting Primary Care Landscape
02/03/2026
Summary
Point of Care Testing (POCT) in UK primary care is defined as medical diagnostic testing performed at or near the site of patient care, rather than within a centralised laboratory infrastructure.
In the context of a modern GP surgery or community hub, this shift represents a move toward an immediate "test-and-treat" paradigm that eliminates the traditional administrative burden of sample logistics.
This transition provides diagnostic-grade results within the timeframe of a single consultation, allowing for clinical actions to be taken before the patient leaves the building.
By decentralising these essential services, clinicians can facilitate same-day treatment adjustments, improve triage accuracy for acute presentations, and streamline longitudinal monitoring for complex chronic conditions.
While this approach aligns with the NHS 10-Year Plan’s focus on community-based diagnostics, successful adoption requires navigating complex variables including procurement structures and IQC/EQA compliance.
To achieve sustainable outcomes, the implementation must be treated as a comprehensive clinical service underpinned by robust staff training and seamless data integration into the patient record.
Furthermore, the use of connected ecosystems ensures that results are automatically coded, providing the transparent audit trails necessary for modern primary care governance.
When managed as a high-velocity operational capability rather than a standalone tool, POCT reduces the reliance on secondary care escalations and significantly enhances overall patient flow.
This article examines how to leverage these systems as a strategic asset to manage increasing primary care pressures while maintaining rigorous safety and governance standards.
Why POCT Is Used in Primary Care
The adoption of POCT in general practice is driven by the need to compress the diagnostic window.
This immediate data facilitates same-day medication adjustments and reduces the volume of "safety-netting" appointments, effectively increasing overall practice capacity.
Furthermore, POCT serves as a critical risk-management tool. A negative CRP or Troponin result in the right clinical context can prevent unnecessary secondary care escalations.
Ultimately, the value of POCT is found as much in the avoidance of unnecessary interventions as it is in the speed of diagnosis.
However, these clinical benefits are only realised when testing is fully integrated into existing practice pathways.
POCT Statistics and Evidence in Primary Care
Evidence suggests that:
• Research into CRP testing in primary care has demonstrated a 24% reduction in antibiotic prescribing for respiratory tract infections without compromising patient safety.
From a workload perspective, practices utilising integrated POCT report a significant decrease in follow-up administrative tasks, as results are coded and actioned during the initial appointment.
While central labs remain the gold standard for complex analytics, POCT provides the physiological "real-time" data required to manage primary care pressures effectively.
Common POCT Applications in Primary Care
Some common applications of point-of-care-testing in primary care are:
Chronic disease monitoring
• Roche cobas b 101 system: Supports same-visit review of glycaemic control where clinically appropriate.
• Lipid Profiling: Assess cardiovascular risk and dyslipidaemia without requiring a separate phlebotomy appointment or return visit.
• Longitudinal Tracking: Supports structured clinical reviews by monitoring trends in patient data rather than isolated, one-off results.
• Medication Adherence: Provides immediate evidence-based feedback to patients, which can support improved engagement with treatment plans.
Acute presentation assessment
• Roche cobas h 232 / CRP testing: Provides a quantitative measure of inflammation to guide antibiotic stewardship and infection triage.
• Urinalysis and Ketones: Allows for the rapid assessment of metabolic distress, suspected UTI, or potential diabetic ketoacidosis (DKA).
• Rule-out Capabilities: Facilitates objective risk stratification for suspected DVT or cardiac events, supporting validated clinical assessment pathways and contributing to more informed referral decisions where appropriate.
• Selective Testing: Used as a targeted support tool to augment clinical judgment, rather than a replacement for physical assessment.
Preventive and screening use
• Haemoglobin Testing: Rapid screening for anaemia in pregnant patients or those presenting with fatigue-related symptoms.
• Opportunistic Screening: Captures diagnostic data from "hard-to-reach" patients who may not attend follow-up laboratory appointments.
• Community-Based Screening: Aligns with local prevalence policies for infectious diseases or metabolic screening within the PCN.
Digital Connectivity and Data Flow
A critical component of modern POCT is the transition from standalone "desktop" units to connected ecosystems.
Automated data handling is no longer a luxury but an aspect of governance that is increasingly expected in large-scale primary care operations. Such as:
• Automated Record Entry: Results flow directly from the device to the patient record, eliminating transcription errors associated with manual entry.
• SNOMED CT Coding: Supports accurate coding for QOF and audit requirements.
• Centralised Oversight: Allows Practice Managers or Lead Nurses to monitor QC status and reagent lot numbers across multiple sites from a single dashboard.
• Audit Trail Security: Provides a time-stamped record of who performed the test, on which device, and the corresponding quality control status.
Operational Considerations in GP Practices
Integrating POCT requires a shift in practice workflow.
Many surgeries utilise Healthcare Assistants (HCAs) to perform tests prior to the GP consultation, ensuring the clinician has data points available at the start of the 10-minute slot.
This "pre-consultation" model minimises the impact on appointment length.
Training is a non-negotiable operational pillar; all staff must undergo initial certification and annual competency reassessments to ensure analytical accuracy.
Roche supports this through structured training pathways and digital documentation, helping practices maintain a record of staff proficiency even amidst high turnover.

Governance and Compliance
Some considerations with POCT governance and compliance.
Quality assurance
Governance in POCT is an ongoing obligation.
Internal Quality Control (IQC) must be performed daily or per-batch to verify device performance, while External Quality Assessment (EQA) provides an independent check against national standards.
This dual-layer approach ensures that POCT offers a reliable measure that complements those from a central laboratory.
Regulatory and contractual considerations
CQC inspections increasingly focus on the "Well-led" and "Safe" domains regarding diagnostic accuracy.
Compliance with ISO 15189 or ISO 22870 standards, even if not formally accredited, provides a framework for multidisciplinary oversight.
Understanding these requirements is essential, as poor governance is a primary blocker to sustainable POCT adoption.
Data, Records, and Clinical Liability
The integration of results into the clinical record (EMIS/SystmOne) is vital for continuity of care.
While manual entry is common, automated connectivity reduces transcription errors and ensures all tests are correctly SNOMED coded.
From a medicolegal perspective, POCT results form part of the clinical record and must be afforded appropriate weight, with interpretation supported by documented governance and clinical correlation. Therefore, clinicians must document the device used and the QC status.
Addressing the risk of false positives or negatives through clinical correlation is where the article earns the trust of the cautious practitioner.
Environmental and Sustainability Impact
As the NHS moves toward "Net Zero," the environmental footprint of diagnostics is under increasing scrutiny.
Moving the test to the patient has significant secondary benefits for practice sustainability goals.
• Reduced Patient Travel: Eliminating the "test then return" model can lower the carbon footprint associated with multiple patient journeys.
• Waste Management: Many modern Roche POCT systems are designed to minimise reagent waste through the use of unit-dose testing strips and cartridges.
• Streamlined Logistics: Reduces the frequency of medical courier collections required for cold-chain transport of blood samples to central labs.
• Resource Optimisation: Decreases the use of consumables like plastic vacutainers and needles by utilising finger-prick capillary samples where appropriate.
Financial and Commissioning Factors
The "perverse incentive" remains a significant structural challenge in the UK.
While a practice pays for the POCT device and reagents, the savings from reduced antibiotic prescribing or avoided A&E attendances often accrue to the Integrated Care Board (ICB) or secondary care.
However, when viewed through the lens of staff time and appointment efficiency, the "cost per patient journey" often favours POCT.
Identifying local commissioning streams or PCN-level funding is often the key to making the financial case for adoption.
Patient Experience
Patients report higher levels of satisfaction when results are delivered immediately, as it reduces the anxiety associated with waiting for lab returns.
The "one-stop-shop" model also removes the logistical burden of multiple appointments, which is particularly beneficial for elderly or vulnerable populations.
However, clinicians must manage expectations, clearly explaining that POCT is a specific tool with defined limitations.
Technology and Device Evaluation
When evaluating hardware, analytical accuracy and ease of use are paramount.
A device must be robust enough for a busy treatment room while providing lab-comparable sensitivity.
Roche’s POCT ecosystems are underpinned by established clinical validation processes, alongside technical design considerations.
A "fit-for-purpose" device is one that connects to the practice network and requires minimal maintenance from non-laboratory staff.
POCT vs Laboratory Testing
| Feature | Point of Care Testing (POCT) | Central Laboratory |
|---|---|---|
| Turnaround Time | 2–15 Minutes | 24–48 Hours |
| Operator | Trained Clinical Staff | Qualified Scientists |
| Volume | Low/Targeted | High/Automated |
| Cost Per Test | Higher (Reagents/Staff) | Lower (Economy of Scale) |
POCT and labs are not competitors; they are complementary. The lab provides the deep analytical "truth," while POCT provides the "actionable now."
Strategic Role of POCT in Primary Care
The NHS 10-Year Plan emphasises a "Left Shift", moving diagnostics out of hospitals and into the community.
POCT is the technical engine of this shift.
By establishing community diagnostic capabilities now, PCNs can future-proof their service delivery models and align with integrated care goals.
Connectivity and data visibility will be the hallmarks of the next generation of primary care diagnostics.
