Core Responsibilities

Primary Functions

Perform and interpret complex clinical laboratory assays across assigned disciplines (e.g., haematology differentials, blood film review, microbial culture and sensitivity, PCR/qPCR for infectious agents, immunoassays such as ELISA), ensuring all results meet clinical validation criteria and turnaround-time targets.
Manage end-to-end specimen processing including specimen receipt, triage, accessioning, prioritization, extraction, sample preparation, and secure disposal while strictly following SOPs and chain-of-custody procedures to maintain sample integrity and patient safety.
Operate, calibrate, qualify, and perform routine maintenance on automated analyzers (haematology, biochemistry, immunoassay), molecular platforms (qPCR, real-time PCR), and microbiology instruments; document instrument performance and escalate technical issues to service engineers as needed.
Lead and document method validation, verification, and implementation activities for new assays or platforms, including establishing performance characteristics (sensitivity, specificity, precision, linearity) and producing technical validation reports aligned with ISO 15189/CLIA requirements.
Apply quality-control and quality-assurance procedures daily, including review of QC charts, internal controls and external quality assessment (EQA) results; initiate corrective actions and CAPA when deviations occur and maintain traceable records.
Review, interpret and authorize laboratory test results, providing clinical correlation and guidance to clinicians when necessary, documenting any amended results and ensuring appropriate clinical communication for critical or unexpected findings.
Maintain and manage data in the Laboratory Information Management System (LIMS), ensuring accurate patient demographics, test selection, result entry, instrument interfaces, and seamless electronic reporting to clinicians and EHR systems.
Participate in root cause analysis for non-conformances, lead or contribute to CAPA investigations, implement process improvements, and document outcomes to enhance laboratory reliability and regulatory compliance.
Supervise, train, and mentor junior scientists, biomedical technicians and laboratory assistants by developing competency assessments, delivering formal training, and assessing ongoing technical proficiency.
Ensure laboratory compliance with national and international regulations and standards (ISO 15189, CLIA, CAP, GLP, local health authority rules), prepare documentation and support external inspections and accreditation audits.
Prepare, review and update standard operating procedures (SOPs), technical manuals, and safety documentation to reflect current best practices, new methods, and changes to instrumentation or regulatory guidance.
Manage reagent inventory, procurement, and lot control; carry out reagent qualification, stability checks and prepare reagent master records to minimize stockouts and maintain assay consistency.
Conduct microbiological isolation and identification workflows, perform antimicrobial susceptibility testing (AST) using standardized methods (disk diffusion, automated MIC determination), and interpret resistance patterns for clinical reporting.
Execute molecular diagnostic workflows including nucleic acid extraction, PCR setup, contamination control, and result interpretation while maintaining unidirectional workflow and strict contamination prevention measures.
Ensure laboratory biosafety and infection control protocols are followed by all staff, manage waste segregation and disposal, and coordinate incident reporting for exposure events in line with institutional policies.
Generate and analyze laboratory performance metrics (turnaround times, test volumes, error rates), prepare periodic operational reports for laboratory leadership, and recommend capacity or staffing changes based on data.
Collaborate with multidisciplinary clinical teams (physicians, nurses, transfusion services) to develop testing algorithms, advise on specimen collection best practices, and support clinical decision making through timely consultations.
Support clinical trials and research studies by setting up validated assays, maintaining chain-of-custody documentation, completing study-specific forms, and ensuring GCP/GCLP compliance where applicable.
Lead continuous improvement initiatives (Lean, Six Sigma, PDCA), identify bottlenecks in testing workflows, implement process changes to increase productivity and reduce pre-analytical and analytical errors.
Maintain strict documentation for traceability — batch records, QC logs, equipment maintenance, staff competency records — ensuring audit-ready records at all times.
Provide out-of-hours on-call support as required for critical testing, troubleshoot urgent instrument failures, and liaise with external partners for expedited service when patient care is impacted.

Secondary Functions

Participate in departmental meetings, contribute to strategic planning for laboratory services, and assist in budgeting and procurement planning for capital equipment and consumables.
Contribute to the development and delivery of CPD programs, journal clubs, and continuing education for laboratory staff to support skill growth and regulatory competency requirements.
Assist in the evaluation of new diagnostic technologies and vendor selection by performing bench evaluations, cost-benefit analysis, and interfacing with procurement stakeholders.
Support laboratory IT projects including LIMS upgrades, HL7 interfacing, middleware implementation, and test code standardization to improve electronic result distribution.
Act as a subject matter expert for laboratory-related audit queries, incident investigations, and cross-departmental process mapping exercises.
Engage with external quality providers, participate in proficiency testing, and coordinate corrective actions arising from EQA feedback.
