Career Guide
Clinical Laboratory Scientists perform medical laboratory testing that helps clinicians diagnose, treat, and monitor disease. They run and validate tests on blood, tissue, and other specimens, maintain quality and safety standards, and communicate critical results to care teams.

Key Responsibilities

  • Receive, label, and prepare patient specimens for testing
  • Operate laboratory instruments and monitor analyzer performance
  • Perform testing in areas such as chemistry, hematology, microbiology, and blood bank
  • Review results for accuracy and clinical consistency
  • Verify abnormal results using repeat testing or alternative methods
  • Report critical values promptly to the clinical team
  • Troubleshoot instrument issues and test errors
  • Follow quality control routines and document findings
  • Maintain compliance with laboratory regulations and accreditation standards
  • Support method validation and implementation of new tests
  • Train and support new staff and students
  • Follow biosafety practices and infection prevention protocols
