Core Responsibilities

Primary Functions

Receive, verify, and accession patient specimens, ensuring proper patient identification, labeling, and chain-of-custody procedures to maintain specimen integrity and compliance with institutional policies and regulatory requirements (CLIA/CAP/HIPAA).
Perform routine and specialized clinical laboratory testing in chemistry, hematology, coagulation, urinalysis, microbiology, immunoassay and blood bank sections using automated analyzers and manual techniques; accurately execute test procedures according to manufacturers’ instructions and laboratory standard operating procedures.
Prepare, stain, and examine blood and body fluid smears using microscopy to identify cellular morphology, parasites, or abnormal cells; document and escalate findings to senior staff or pathologists when indicated.
Conduct microbiology specimen processing including culture setup, streaking, incubation, reading plates, preliminary identification, and performing susceptibility testing or preparing isolates for referral to reference labs.
Operate and maintain automated hematology and chemistry analyzers (e.g., CBC analyzers, metabolic panels), perform reagent preparation, run controls, and interpret QC data to ensure analytical validity of results.
Perform molecular diagnostic techniques including PCR, NAAT, and other nucleic acid amplification methods when within scope, including preparation of nucleic acid extracts and adherence to contamination control procedures.
Execute blood bank procedures: ABO/Rh typing, antibody screen, crossmatch procedures, issuing blood products under established policies, and performing transfusion compatibility testing; maintain blood bank records and inventory.
Enter, verify, and validate test orders and results in the Laboratory Information System (LIS); troubleshoot interfacing issues and ensure timely, accurate electronic reporting to clinicians and the electronic medical record (EMR).
Run, document, and evaluate internal and external quality control (QC) and participate in proficiency testing programs; initiate corrective actions for QC failures and complete required documentation and notifications.
Troubleshoot instrumentation, perform routine calibration and preventive maintenance, and coordinate with biomedical engineering or vendor support for repair or advanced servicing to minimize downtime.
Identify, document, and report critical or panic values immediately to ordering providers per institutional policy; maintain a log of critical call notifications and follow-up.
Adhere to and enforce biosafety, infection control, and hazardous waste disposal procedures including PPE use, spill response, and sharps safety; participate in safety drills and risk assessments.
Maintain accurate inventory of reagents, supplies, and blood products; place reagent and supply orders, monitor expiration dates, and rotate stock to prevent shortages and waste.
Prepare and maintain documentation required for regulatory compliance including quality manuals, SOPs, equipment logs, temperature logs, and audit responses for CLIA, CAP, or state inspections.
Participate in validation, verification, and implementation of new assays and instrumentation, including running parallel testing, documenting analytical performance, and training staff on updated procedures.
Provide training and mentorship to new technicians, students, and cross-trained staff; demonstrate competency assessments and maintain training records.
Collaborate with healthcare providers, nursing staff, and laboratory leadership to clarify test orders, discuss specimen requirements, and communicate unexpected test results or specimen issues.
Participate in continuous process improvement initiatives to increase laboratory efficiency, reduce turnaround time (TAT), and improve patient safety — including Lean, Six Sigma, or departmental quality projects.
Maintain confidentiality and professional conduct in all interactions; comply with HIPAA and institutional privacy policies.
Support after-hours, weekend, or on-call rotation as needed to ensure 24/7 clinical laboratory coverage, including performing urgent testing and instrument troubleshooting during off-shifts.
Prepare specimens for transport to reference laboratories, ensure proper documentation and packaging, and track shipments to confirm receipt and testing.
Assist in the development and review of laboratory SOPs, test menus, and job aids; contribute to competency testing, audits, and corrective action tracking.
Participate in departmental meetings, regulatory readiness planning, and continuing education activities to remain current with best practices and evolving laboratory technologies.
Respond promptly to emergent public health testing needs (e.g., outbreak testing, surge capacity), scaling work processes and collaborating with leadership and external partners to meet increased testing demands.

Secondary Functions

Support data queries, lab metrics reporting, and performance dashboards by providing accurate test volumes, TAT, and QC data to laboratory management.
Contribute to inventory optimization and cost-control initiatives by recommending reagent consolidation, vendor comparisons, and usage trends.
Engage in interdisciplinary committees (infection control, transfusion committee) to represent the laboratory perspective and advise on testing-related policies.
Assist in the validation of middleware and LIS interfacing projects to improve result routing, reflex testing, and electronic result delivery.
Help coordinate student rotations and clinical affiliations by providing structured learning objectives and evaluating trainee performance.
