  • Prepare specimens for testing by performing standardized centrifugation, aliquoting, decanting, fractionation, pooling, and mixing using calibrated equipment while following written SOPs to preserve analyte integrity for downstream assays.
  • Label and barcode specimen containers, cryovials, and aliquot tubes with machine-readable and human-readable identifiers, ensuring label adhesion, placement, and readability for automated analyzers and manual handling.
  • Manage cold-chain logistics: place specimens into refrigerators, freezers (–20°C, –80°C), liquid nitrogen storage, or controlled temperature shippers, monitor temperature logs, respond to excursions, and document corrective actions to ensure sample viability.
  • Accurately prepare and package specimens for same-day and overnight shipment according to IATA, DOT, and institutional biosafety regulations, including dry ice handling, UN3373 or UN1845 compliance, and completion of shipping manifests and chain-of-custody forms.
  • Conduct routine instrument and equipment setup, calibration, and preventative maintenance for centrifuges, refrigerators/freezers, vortexers, biosafety cabinets, and barcode printers; escalate malfunctions and maintain equipment logs.
  • Execute quality control and quality assurance tasks such as sample acceptance/rejection criteria checks, hemolysis/insufficient-volume assessment, discrepancy reconciliation, and completion of nonconformance reports when necessary.
  • Maintain specimen inventory and disposition records, managing retention schedules, sample withdrawals, and destruction according to SOPs, consent restrictions, and regulatory requirements.
  • Follow strict biosafety, bloodborne pathogen, and PPE protocols when handling potentially infectious material, including adherence to BSL-2 practices, sharps disposal, spill cleanup, and exposure reporting procedures.
  • Troubleshoot sample processing problems, resolve mismatches between requisitions and specimens, contact ordering clinicians or study coordinators for clarification, and document communications in LIMS for audit trails.
  • Support molecular and serology pre-analytic workflows by preparing nucleic acid extraction plates, aliquots for PCR/NGS, and performing pre-PCR clean-room techniques (as applicable) to minimize contamination risk.
  • Perform accurate data entry and reconciliation for accession logs, test orders, and sample location updates, ensuring compliance with HIPAA and data security policies when handling patient or study data.
  • Participate in daily huddles and workflow planning to align specimen intake volumes with staffing, prioritize STAT and critical samples, and contribute to continuous improvement initiatives that reduce TAT and errors.
  • Assist with validation and verification activities for new specimen types, collection devices, or shipping procedures by executing protocol steps and documenting performance metrics under supervision of senior staff or QA.
  • Support proficiency testing and external quality assessment exercises by preparing and processing blind samples according to instructions, documenting results, and safeguarding sample integrity.
  • Maintain clean, organized work areas by performing routine housekeeping, inventory counts of consumables (tubes, labels, cryovials), ordering supplies, and ensuring availability of PPE and sample handling materials to maintain uninterrupted operations.
  • Ensure all specimen handling and processing activities are documented accurately in laboratory notebooks, electronic records, and LIMS, creating an auditable trail to support CAP/CLIA inspections and internal audits.
  • Train and mentor new hires and cross-train laboratory staff on specimen accessioning, cold-chain management, LIMS navigation, and standard pre-analytic techniques to maintain team capacity and competence.
  • Implement and follow SOPs and updated policies for emerging specimen types (saliva, swabs, dried blood spots, multi-omics collections), adapting workflow and documentation to ensure compliance with study or clinical protocols.
  • Coordinate with phlebotomy, reception, nursing, and courier teams to schedule specimen pickups, clarify collection requirements, and communicate status updates for delayed or problematic specimens.
  • Participate in root cause analyses for specimen-related errors and contribute to corrective and preventive action (CAPA) plans, tracking metrics to reduce rejection rates and improve sample quality.
  • Monitor lot numbers, expiration dates, and storage conditions for sample collection kits and reagents used in pre-analytic processing, performing first-in/first-out (FIFO) management where applicable.
  • Comply with institutional and regulatory training requirements, maintain up-to-date certifications (e.g., bloodborne pathogens, HIPAA, biosafety), and document continuing education related to specimen handling and laboratory safety.

Secondary Functions

  • Assist laboratory operations teams with ad-hoc inventory requests, sample retrievals for research studies, and coordination of archived specimen access.
  • Contribute to implementation of laboratory information system (LIMS) enhancements by providing pre-analytic workflow input and validating LIMS barcode/labeling configurations.
  • Support small-scale data reconciliation tasks (e.g., export sample location reports, cross-check LIMS vs. physical inventory) to aid lab managers and data teams.
  • Participate in lab safety committees, provide feedback on biosafety SOPs, and help update training materials and quick-reference guides for specimen handling.
  • Cross-train in related lab departments (microbiology accessioning, molecular prep, biobanking) to ensure flexible coverage during peak volumes or staff absences.
