  • Critically analyze and interpret test results, correlating findings with patient history and clinical conditions to ensure the diagnostic validity of the data.
  • Promptly and accurately report critical or life-threatening test results to physicians, nurses, or other designated healthcare personnel in line with established communication protocols.
  • Systematically troubleshoot and resolve instrument malfunctions, reagent integrity issues, and complex technical problems to minimize testing delays and maintain result accuracy.
  • Actively participate in external proficiency testing programs (e.g., CAP surveys) by analyzing unknown samples and submitting results for peer-group evaluation.
  • Maintain comprehensive and error-free records of all tests performed, patient data, quality control results, corrective actions, and instrument maintenance activities.
  • Strictly adhere to all laboratory safety procedures, including the consistent use of personal protective equipment (PPE) and the proper handling and disposal of biohazardous materials.
  • Assist in the evaluation, validation, and implementation of new testing methodologies, instrumentation, and laboratory procedures to advance the lab's capabilities.
  • Perform and document instrument-to-instrument and method-to-method correlation studies as required for validating new equipment or procedures.
  • Manage the inventory of laboratory supplies and reagents, ensuring adequate stock levels are maintained, monitoring expiration dates, and placing orders as necessary.
  • Accurately enter and verify patient demographic information and test results within the Laboratory Information System (LIS) to ensure data integrity.
  • Provide technical guidance, mentorship, and support to Laboratory Assistants, Phlebotomists, and other members of the laboratory support staff.
  • Engage in mandatory and voluntary continuing education activities to remain current with the latest advancements in laboratory medicine, techniques, and regulatory standards.
  • Uphold absolute patient confidentiality and comply with all HIPAA regulations and institutional privacy policies without exception.
  • Perform specialized testing in disciplines such as molecular diagnostics, flow cytometry, toxicology, or andrology, based on the specific laboratory's scope of service.
  • Contribute to the hands-on training and development of new employees and students during their clinical rotations within the laboratory.
  • Evaluate the technical competency of other testing personnel as delegated by the laboratory supervisor, providing constructive feedback and documentation.
  • Identify and meticulously document non-conformances, initiating and participating in the investigation and resolution of quality events or process deviations.
  • Contribute to the development, review, and revision of Standard Operating Procedures (SOPs) for the department to ensure they reflect current best practices.

Secondary Functions

  • Support ad-hoc data requests and exploratory data analysis for quality improvement projects and clinical research.
  • Contribute to the organization's overarching goals for patient safety, quality of care, and positive patient experience.
  • Collaborate with nurses, physicians, and other clinical staff to clarify ambiguous test orders and communicate specific specimen collection requirements.
