Which HL7 message type is used by the LIS to transmit laboratory results to an ordering physician's EHR system?
Answer: ORU^R01
The ORU^R01 (Observation Result Unsolicited) message is the standard HL7 v2.x format for transmitting laboratory results to receiving systems.
A laboratory is adopting FHIR R4 for interoperability. Which FHIR resource would primarily carry a laboratory observation result?
Answer: Observation
The FHIR Observation resource carries individual measured or calculated test values, while DiagnosticReport groups multiple observations into a report.
Total laboratory automation (TLA) systems primarily benefit laboratories by:
Answer: Reducing manual specimen handling steps, improving throughput and reducing pre-analytical errors
TLA connects pre-analytical, analytical, and post-analytical modules to reduce manual touchpoints, improving efficiency and specimen integrity.
In a laboratory LIMS validation project, which document type defines the expected system behavior that will be tested during validation?
Answer: User Requirements Specification (URS)
The User Requirements Specification (URS) formally captures what the system must do, forming the basis against which all validation testing is conducted.
A consultant recommends a track-based specimen routing system with buffer storage. Which operational challenge does buffer storage specifically address?
Answer: Managing workload surges by holding specimens when analyzers are busy
Buffer storage modules hold specimens when downstream analyzers are at capacity, preventing backlog and maintaining steady instrument utilization during peak periods.
Which type of laboratory barcode symbology is preferred for tube labeling because it can encode specimen ID, collection date, and accession number in a compact 2D format?
Answer: PDF417 or Data Matrix
2D barcodes like PDF417 and Data Matrix store much greater data density than 1D codes, making them ideal for encoding multiple specimen attributes on a small label.
When evaluating laboratory software for 21 CFR Part 11 compliance, which capability is MANDATORY?
Answer: Audit trails, electronic signatures, and access controls for electronic records
21 CFR Part 11 requires that electronic records systems maintain audit trails, support electronic signatures, and enforce access controls to ensure data integrity.
