Study Notes

Pre-Analytical Phase

Clinician orders tests based on patient need; adherence to ordering protocols is crucial to prevent unauthorized or inappropriate orders.
Laboratory staff interacts with patients upon arrival; timely service and a friendly environment enhance customer satisfaction.
Requisitions undergo thorough reviews to ensure completeness; missing patient data or clinical history can lead to clerical errors.
Correct sample type identification is essential; communication regarding specimen collection requirements must be clear to avoid missteps.
Blood specimens collected by clinicians or laboratorians must follow phlebotomy guidelines to avoid errors, such as wrong tube use or improper labeling.
Specimens are logged with essential information for tracking; clerical accuracy is vital to avoid misidentification.
Acceptance of specimens is based on criteria; rejected specimens may result from being unsatisfactory or poorly labeled.
Laboratory prioritizes testing requests, distinguishing between STAT and routine; timely processing and handling of samples are essential to avoid delays.

Analytical Phase

Routine quality control checks are performed prior to specimen analysis; maintaining SOP and guidelines for equipment ensures reliability.
Specimen analysis requires adherence to specific SOPs; shortcuts can compromise the integrity of test results.
Test results undergo a rigorous review for accuracy and validity; cross-checking and proper quality monitoring are essential.

Post-Analytical Phase

Test results must be accurately recorded and logged; clerical errors can occur if results are improperly documented.
Communication of test results to clinicians is performed via written reports or urgent verbal notifications, especially for critical values; timely delivery is essential.
Documentation and records must be maintained in a retrievable manner; adherence to the document retention schedule ensures compliance and prevents data loss.
