Laboratory Operations
What this domain tests
Laboratory Operations covers organizational structure, CLIA role assignment, workflow and staffing, information systems, competency, document control, send-outs, point-of-care testing, and downtime planning.
Structure and roles
- CLIA defines the laboratory director, technical supervisor, clinical consultant, general supervisor, and testing personnel. Delegation is permitted only when it is in writing and consistent with the regulations.
- The preanalytical phase (ordering, collection, labeling, transport, accessioning) accounts for the largest share of laboratory errors; specimen rejection criteria must be written, applied consistently, and documented.
- Point-of-care testing needs the same oversight as main-laboratory testing: competency, QC, correlation with central methods, and a defined operator list.
Systems and process
- LIS interfaces must be validated before go-live and after major changes; bidirectional interfaces need audit trails and error handling.
- Downtime procedures must specify paper backup, result entry after recovery, and how critical results are communicated.
- Send-out testing requires documented reference laboratory selection, specimen stability, tracking, and turnaround monitoring.
- Competency assessment includes direct observation, monitoring of result recording and reporting, review of records, and problem-solving; initial assessment, semiannual in the first year, annual thereafter.
Worked example
A stat chemistry section performs 12,000 tests per month at an average of 4 minutes hands-on time each. Total monthly minutes = 48,000, or 800 hours. With 2,080 paid hours per year and 15% nonproductive time, productive hours per FTE are about 1,768 per year, or 147 per month. 800 ÷ 147 ≈ 5.4 FTE. Reasoning: use productive hours, not paid hours, and state the assumptions; the same formula scales for a new test menu.
Traps that cost marks
- Treating training and competency assessment as the same activity.
- Bringing an interface live without validation.
- Having no documented downtime plan.
- Monitoring send-out turnaround only when a clinician complains.
- Allowing unlisted operators to run point-of-care devices.
