Assessing Your TB Laboratory’s Readiness for Phase One
A tuberculosis laboratory quality management system begins with a clear understanding of current practice. Before a laboratory starts phase one of the GLI Quality Tool roadmap, it should determine whether the basic conditions for organized improvement are in place: leadership support, defined responsibilities, reliable records, safe work areas, and enough time for staff to participate.
Readiness does not mean that every quality requirement has already been met. Phase one is intended to help laboratories establish a foundation and identify gaps. The assessment should therefore show what is working, what is missing, and which weaknesses could affect patient results, staff safety, or the continuity of testing services.
A useful readiness review combines document checks, staff discussions, workplace observation, and a practical review of daily laboratory processes. The result should be a short, evidence-based baseline that the laboratory can use to plan its first quality activities.
Clarify the purpose and scope of the assessment
Start by defining which services, rooms, instruments, and personnel will be included. A TB laboratory may perform microscopy, molecular testing, culture, drug susceptibility testing, specimen referral, or several of these activities. Readiness can differ significantly between sections, so the review should cover the actual testing pathway rather than treating the laboratory as a single unit.
The assessment should follow a specimen from receipt to reporting and referral of results. This makes it easier to identify gaps at handover points, such as incomplete request forms, unclear acceptance criteria, delays in processing, or results released without appropriate review. Include support functions that influence quality, including procurement, equipment maintenance, biosafety, information management, and waste disposal.
Use the phase-one checklist as a guide, but do not treat it as a paperwork exercise. For every requirement, ask what evidence would demonstrate that the practice exists and is used consistently. A signed procedure, a completed temperature log, an interview with a technologist, or direct observation may each provide different parts of the answer.
Confirm leadership, roles, and available capacity
A laboratory is more likely to progress when a manager or senior technical lead takes visible responsibility for quality. Readiness includes having someone who can coordinate the work, bring staff together, track actions, and communicate unresolved problems to facility or program leadership. The role does not need to be a new full-time position, but its responsibilities should be explicit.
Check whether staff understand who approves procedures, reviews quality indicators, investigates errors, authorizes reports, and communicates with clinicians or referral sites. If these duties depend on informal knowledge, the laboratory may struggle when staff rotate, take leave, or transfer. A basic organization chart, duty assignment, or quality responsibility matrix can reveal whether accountability is clear.
Capacity also includes time and resources. Ask whether staff can attend short quality meetings, complete records, perform internal reviews, and follow up corrective actions without disrupting essential testing. Review staffing levels, workspace, supplies, information technology, and maintenance support. A realistic phase-one plan should reflect operating conditions rather than assume resources that are not available.
Examine the foundation across the quality essentials
The twelve Quality Systems Essentials provide a structured way to assess the laboratory’s baseline. Review areas such as organization, personnel, equipment, purchasing and inventory, process management, information management, documents and records, customer focus, assessment, nonconforming event management, continual improvement, and facilities and safety. The purpose is to identify connections between these areas, not to inspect them in isolation.
Documentation is especially important because staff need a consistent reference for how work is performed and how decisions are recorded. Look for controlled procedures, current forms, accessible job aids, revision histories, and rules for retaining records. This practical guide to documentation in TB quality management can help the assessment team distinguish useful quality records from documents that exist only for inspection.
Use interviews to test whether written procedures reflect actual practice. Ask staff to explain how they receive specimens, manage invalid results, respond to equipment failure, handle spills, and report problems. Then compare their answers with the relevant documents and observe the process where possible. Differences may indicate outdated procedures, inadequate training, or a workflow that has evolved without formal review.
| Readiness area | Evidence to review | Signs of a phase-one gap |
|---|---|---|
| Leadership and responsibilities | Appointment letters, meeting records, duty assignments | No named quality lead or unclear authority |
| Personnel | Training files, competency records, staffing plan | Staff perform tests without documented training or competency review |
| Equipment and supplies | Inventory, maintenance logs, temperature records, stock cards | Critical equipment or reagents lack status records |
| Documents and records | Approved procedures, forms, revision history | Multiple versions or missing records |
| Safety and facilities | Risk assessments, incident reports, waste procedures | Unsafe workflow or inconsistent use of protective measures |
| Testing and reporting | Sample pathway, worksheets, result review, referral records | Delays, incomplete data, or unclear result authorization |
| Assessment and improvement | Quality indicators, error logs, action plans | Problems are recognized but not tracked to resolution |
Test the specimen-to-result workflow
A readiness assessment should examine the complete testing cycle, including pre-analytical, analytical, and post-analytical activities. Confirm that specimen collection guidance, labeling requirements, transport conditions, acceptance criteria, and rejection procedures are defined and understood by both the laboratory and sending sites.
Within the testing process, review internal quality control, environmental monitoring, instrument checks, reagent verification, and result interpretation. Determine whether staff can recognize an unacceptable control result and know what to do next. Check whether equipment downtime, power interruptions, contamination events, and invalid tests are recorded and investigated.
Turnaround time is a useful indicator because it exposes weaknesses across several stages of the workflow. Establish how the laboratory defines the start and end points, then review a sample of recent records for delays and missing timestamps. Guidance on monitoring result turnaround can support a simple baseline that the laboratory can improve during later phases.
Rate evidence and identify critical risks
Use a clear rating method so that the assessment communicates priorities rather than producing a long undifferentiated list. A three-level scale can work well: established, partly established, or absent. Add a separate note for requirements that were not verifiable. This prevents assumptions from being recorded as evidence and highlights areas requiring follow-up.
Not every gap has the same consequence. Give immediate attention to risks that could produce incorrect results, expose staff or patients to infection, compromise specimen identity, or interrupt essential services. For example, a missing document revision date may require correction, while an absence of biosafety controls or unreliable result authorization may demand urgent action before routine expansion.
Discuss the findings with the staff who perform the work. Their experience can explain why a process fails and may reveal practical solutions that are not visible in documents. Record the evidence, risk, responsible person, and proposed action for each priority gap. Keep the assessment concise enough to review regularly.
Recommended actions before beginning phase one
Once the baseline is complete, convert it into a manageable starting package. Avoid launching many activities at once. Select a small number of foundational actions that improve control across several quality areas and create evidence for future review.
A practical first set of actions may include:
- Appoint a quality coordinator and define responsibilities for managers, testing staff, and support personnel.
- Create a master list of current procedures, forms, logs, and records, then remove or withdraw obsolete versions.
- Map the specimen-to-result workflow and select indicators such as rejected specimens, invalid tests, amended reports, and turnaround time.
- Verify that essential safety controls, equipment records, reagent storage, and waste procedures are functioning.
- Establish a regular quality meeting with an action log, named owners, due dates, and documented follow-up.
After these actions are assigned, set a review date rather than waiting for a formal audit. The review should check whether tasks were completed, whether staff use the new controls, and whether the changes have reduced risk. Small, visible improvements can build confidence and make the wider roadmap easier to sustain.
The phase-one readiness decision should be based on capability to begin organized improvement, not on perfect performance. A laboratory is ready when leadership accepts the findings, staff know their roles, urgent risks are controlled or actively managed, and the laboratory can collect reliable evidence about its work.
Download the relevant GLI Quality Tool materials, complete the checklist with the people who perform and oversee testing, and turn the findings into a dated action plan. Begin with the highest-risk gaps, review progress regularly, and use each completed action to strengthen the laboratory’s path through the quality roadmap.
