Study Notes
Pre-analytical Phase
- Clinician places orders based on patient needs; requires adherence to ordering protocols to prevent unauthorized and inappropriate orders.
- Patient interacts with the laboratory staff upon presentation; effective customer service is critical to avoid delays and negative interactions.
- Requisition forms must be completed and reviewed for accuracy; common pitfalls include incomplete patient data and clerical errors that can compromise specimen acceptability.
- Laboratory staff determine the type of specimen needed for testing by reviewing requests; failing to follow specimen requirements can lead to collection errors.
- Blood and non-blood samples are collected by clinicians or laboratory personnel; training ensures competent specimen collection to avoid injuries or wrong specimen collection.
- All specimens must be logged with proper information; errors in logging can lead to inadequate tracking and mismanagement.
- Specimens are accepted or rejected based on criteria; hazards, labeling issues, and specimen quality must be monitored to ensure reliable results.
- Assigned tests are prioritized (STAT vs. routine); processing delays can result from inefficient handling of multiple tests or centrifuge requirements.
Analytical Phase
- Routine quality checks are conducted prior to testing to validate reagents and calibrate equipment; failure to follow SOPs can lead to compromised results.
- Specimens are analyzed according to established procedures; shortcuts or SOP deviations can lead to inaccurate outcomes.
- Test results are reviewed for accuracy and validity, requiring careful cross-checking; inadequate validation can result in errors in reporting.
Post-analytical Phase
- Test results are recorded meticulously in logbooks; clerical errors can arise from discrepancies in data presentation.
- Laboratory staff communicate results to clinicians through written or verbal reports, emphasizing the importance of timely notification, especially for critical values.
- Document management involves maintaining, filing, and storing results correctly; adherence to retention schedules is vital to ensure retrievability and to prevent data loss due to environmental damage.
