Medical Laboratory Sciences Practice and Professional Regulation

  • In Kenya, the laboratory profession is regulated under the Medical Laboratory Technicians and Technologists Act, which establishes the KMLTTB as the licensing and disciplinary body for laboratory practitioners.

  • Registration categories typically include student/attachee, registered technician (diploma level), registered technologist (degree level), and specialist or postgraduate registration; each carries a defined scope of practice.

  • Annual practising licence renewal is conditional on evidence of continuing professional development; practising without a valid licence is an offence subject to sanctions.

  • Scope-of-practice rule: a technician works under defined supervision protocols, while a technologist may independently authorise and interpret results within accredited test menus.

  • Mandatory notification: laboratories must report notifiable diseases and critical/panic values to the requesting clinician and, where required, to public health authorities within defined timeframes.

  • Records rule: request forms, worksheets, and reports are retained per national and accreditation requirements (commonly a minimum of five years for clinical records, longer for transfusion and occupational health records).

  • Only a licensed practitioner may sign out a diagnostic report; delegation of result authorisation requires documented competency assessment and institutional policy.

  • Disciplinary pathway: complaint or inspection finding, investigation, hearing before the board's disciplinary committee, then outcomes ranging from caution to suspension or removal from the register.

Laboratory Ethics, Professionalism and Compliance

  • Four core bioethical principles: respect for autonomy, beneficence, non-maleficence, and justice; apply them to consent, test selection, and equitable access decisions.

  • Confidentiality rule: patient results are disclosed only to the patient, authorised clinicians, or as required by law; minimum-necessary disclosure applies to insurers, employers, and research use.

  • Informed consent is required before HIV testing, genetic testing, and research use of stored samples; exceptions are limited to statutory public health or court-ordered situations.

  • Conflict-of-interest rule: disclose any financial interest in a supplier, referral laboratory, or test kit vendor, and recuse from procurement or evaluation decisions involving that party.

  • Competence boundary rule: decline or refer a test or interpretation outside one's training rather than issue an unverified result; document the referral.

  • Research ethics: protocols involving human samples require ethics committee approval, and anonymised residual samples still require consent or a documented waiver.

  • Error disclosure: a known analytical or reporting error affecting patient care must be disclosed promptly to the clinician and documented in the incident system, not concealed.

  • Anti-fraud rule: never alter a result, backdate a record, or report an unperformed test; such acts constitute professional misconduct and possible criminal fraud.

Laboratory Quality Management

  • Quality system essentials span organisation, personnel, equipment, purchasing, process control, documents and records, information management, incident management, assessment, and continual improvement.

  • Quality control rule: run at least two levels of control (normal and abnormal) per testing day or shift, and accept a run only when controls fall within established limits.

  • Westgard multirule: 1-3s is a warning; 2-2s, R-4s, 4-1s, and 10x indicate rejection because they signal systematic or random error.

  • Levey-Jennings charts plot control values against mean and standard deviation; shifts show a sudden mean change, trends show a progressive drift across consecutive runs.

  • Sigma metric = (TEa − |bias|) / CV; higher sigma means fewer controls are needed, lower sigma demands tighter control rules and more frequent verification.

  • External quality assessment (proficiency testing) performance is reviewed by the quality manager; an unsatisfactory result triggers root-cause analysis and corrective action, not simply a repeat test.

  • Corrective action follows root-cause analysis (for example, 5-Why or fishbone); preventive action addresses a potential nonconformity before it occurs.

  • Document control requires unique identifiers, version numbers, approval signatures, effective dates, and retrieval of obsolete copies from all use points.

Validation of Reagents and Equipment

  • Verification vs validation: verification confirms a method performs as the manufacturer claims in your laboratory; validation establishes performance for an in-house or modified method.

  • Core performance characteristics: precision (repeatability and within-lab), trueness/bias, accuracy, analytical measuring range (linearity), limit of detection, limit of quantification, and analytical specificity including interference.

  • Acceptance rule: a reagent lot is released for patient testing only after documented verification of precision and, where applicable, comparison with the current lot or a reference method.

  • Calibration vs verification: calibration assigns values using calibrators; verification checks that the calibrated system meets defined acceptance criteria before reporting patient results.

  • Equipment qualification sequence: design qualification, installation qualification, operational qualification, and performance qualification; each stage is documented before clinical use.

  • Method comparison uses at least 20 patient samples spanning the measuring range, analysed by Deming or Passing-Bablok regression; bias is judged against the total allowable error.

  • Carryover studies alternate high and low samples; carryover percentage must fall below the laboratory-defined limit before the analyser is accepted.

  • Any reagent or equipment change that could affect results requires documented change control, impact assessment, and re-verification before results are released.

Laboratory Education, Training and Continuous Professional Development

  • Competency assessment combines direct observation, blinded rechecking of results, problem-solving case review, and record review; a single method is insufficient evidence of competence.

  • Training records must show objectives, content, trainer qualification, duration, assessment method, outcome, and date, and must be retained for the licence renewal period.

  • New staff require induction training plus supervised practice with sign-off at defined milestones before independent reporting is authorised.

  • Continuing professional development points are typically earned through accredited workshops, conferences, journal clubs, e-learning, and published work; documented evidence is required for renewal.

  • Adult learning principle: training is structured around tasks the learner performs, with feedback and repetition, rather than passive lecture alone.

  • Trainer competence rule: the trainer must hold verified competence in the topic and be authorised by the laboratory director or training coordinator.

  • Refresher training is triggered by a change in method or equipment, a prolonged absence from the bench, or an adverse incident linked to a competence gap.

  • Training effectiveness is evaluated by post-training assessment and by monitoring quality indicators such as error rates in the trained task.

Laboratory Safety and Specimen Management Interface

  • Biosafety levels: BSL-1 for low-risk agents, BSL-2 for clinical diagnostic work with human specimens, BSL-3 for agents transmitted by aerosol with serious consequences.

  • Standard precautions apply to all specimens regardless of diagnosis; gloves, gown, eye protection, and hand hygiene are determined by anticipated exposure, not by known status.

  • Sharps rule: never recap a needle by hand, and dispose of sharps immediately at the point of use into a puncture-resistant container filled to no more than three-quarters.

  • Spill response sequence: alert and evacuate, don personal protective equipment, contain and absorb, disinfect with an appropriate agent such as sodium hypochlorite, then document the incident.

  • Specimen rejection criteria include unlabelled or mislabelled requests, insufficient volume, wrong container or anticoagulant, gross haemolysis, and prolonged transport beyond stability limits.

  • Chain of custody is mandatory for forensic, doping, and medico-legal specimens; each transfer records handler identity, date, time, and specimen condition.

  • Formalin, xylene, and other hazardous chemicals require a current safety data sheet, labelled storage, and documented staff training before handling.

  • Post-exposure prophylaxis for bloodborne exposure must begin as soon as possible after risk assessment; the incident is logged and the source tested under consent rules.

Laboratory Information, Reporting and Governance

  • Critical value rule: a result in the defined panic range is phoned to the responsible clinician within a stated time, and the read-back, recipient name, and time are recorded.

  • Report elements: patient identifiers, unique specimen number, test name and units, reference interval, method or analyser, authorising practitioner, and interpretation where applicable.

  • Delta check rule: compare the current result with the patient's previous value; a change exceeding the defined threshold triggers specimen re-check before release.

  • Laboratory information systems must maintain an audit trail of result entry, amendment, and authorisation; amendments retain the original value and the reason for change.

  • Turnaround time is monitored from specimen receipt (or collection) to report authorisation, and is tracked as a quality indicator with defined targets.

  • Reference intervals must be verified for the local population and analyser; published intervals transferred without verification are a common accreditation finding.

  • Data protection rule: patient identifiable data is accessed on a need-to-know basis, and exports to portable media require encryption and documented authorisation.

Accreditation, Auditing and Continual Improvement

  • ISO 15189 is the international standard for medical laboratories covering quality and competence; accreditation is granted by an authorised national body after assessment.

  • Internal audit cycle: plan the audit, check against standard and local procedures, record findings with evidence, issue corrective actions, and verify closure at a defined interval.

  • Nonconformity grading distinguishes critical (patient safety or invalid results) from major and minor findings; critical findings can suspend testing or accreditation.

  • Management review is held at defined intervals and covers quality indicators, audit results, complaints, EQA performance, resource needs, and improvement actions.

  • Quality indicators are measurable and trended, for example specimen rejection rate, report error rate, turnaround time compliance, and EQA performance score.

  • Risk assessment uses likelihood and severity scoring; high-risk processes receive more frequent monitoring and documented contingency plans.

  • Complaint handling requires logging, investigation, response to the complainant, and analysis of trends feeding into improvement, not just individual resolution.

  • Contingency planning covers analyser breakdown, power failure, and loss of information systems, with documented backup methods and a defined downtime reporting procedure.
