Core Responsibilities

Primary Functions

  • Skillfully perform venipuncture and capillary blood collections from diverse patient populations, including pediatric, adult, and geriatric patients, while ensuring a compassionate and reassuring patient experience.
  • Uphold stringent patient identification protocols by verifying patient information with at least two identifiers before any procedure to prevent pre-analytical errors.
  • Accurately and legibly label all collected specimens at the patient's side with required information, including patient name, date of birth, and collection time/date, to ensure traceability.
  • Receive, sort, and triage a high volume of various biological specimens (blood, urine, tissue, etc.) arriving in the laboratory from different collection points.
  • Operate laboratory centrifuges to spin down blood tubes, carefully separating serum or plasma, and prepare aliquots for testing in different departments.
  • Accession patient and specimen information with exceptional accuracy into the Laboratory Information System (LIS), generating labels and ensuring all data matches the physical sample and requisition form.
  • Prepare specimens for both in-house analysis and shipment to reference laboratories, ensuring proper packaging, temperature control, and adherence to all transportation regulations (IATA, DOT).
  • Monitor and manage pending test logs and troubleshoot issues related to specimen collection, such as missing samples, incorrect tube types, or incomplete orders, by communicating with clinical staff.
  • Perform and document daily, weekly, and monthly maintenance and quality control checks on laboratory equipment, including centrifuges, refrigerators, and freezers.
  • Maintain a clean, sanitary, and well-organized workspace by disinfecting benches, cleaning up spills, and following established safety procedures to prevent contamination.
  • Manage laboratory supply inventory by monitoring stock levels, restocking workstations, receiving new orders, and notifying a supervisor of shortages to ensure uninterrupted workflow.
  • Adhere strictly to all safety and infection control policies, including the use of Personal Protective Equipment (PPE) and proper disposal of biohazardous waste and sharps.

Secondary Functions

  • Answer and direct incoming calls to the laboratory, professionally handling inquiries from physicians, nurses, and patients regarding specimen requirements and test results.
  • Distribute laboratory reports and other correspondence to appropriate clinical areas, ensuring confidentiality and timely delivery of critical information.
  • Assist Medical Technologists with non-technical tasks such as preparing reagents, loading and unloading specimens from automated analyzers, and performing basic instrument maintenance.
  • Participate in the laboratory's quality improvement initiatives by collecting data, identifying opportunities for process enhancement, and contributing to team projects.
  • Train and mentor new employees or students in phlebotomy techniques, specimen processing, and laboratory safety protocols under the guidance of a senior team member.
  • Maintain temperature logs for all temperature-dependent equipment (refrigerators, freezers, incubators) and report any out-of-range readings immediately.
  • File and maintain laboratory records, including requisition forms, quality control logs, and maintenance records, ensuring they are organized and easily retrievable for audits.
  • Support clinical staff by providing appropriate collection containers and instructions to ensure proper specimen collection at the source.
  • Collaborate with other departments, such as nursing and patient registration, to resolve issues related to patient identification, test ordering, and specimen integrity.
