What is used to ensure traceability of specimens in lab processing?

Prepare for the CAMLPR Specimen Collection Competency Test. Practice with diverse question sets including multiple-choice and flashcards. Each question includes hints and explanations to help you become proficient before the exam.

Tracking specimens as they move through processing depends on a unique identifier tied to the container, most often a barcode. Scanning this barcode at every step—when the specimen is received, during processing, during testing, and when results are reported—lets the laboratory information system link the sample to the patient, the order, and the exact tests. This creates an auditable chain of custody and dramatically reduces errors from mislabeling or mixing up samples because data are automatically captured and cross-checked.

Other options don’t provide the same reliable traceability. Sterile gloves protect against contamination but don’t identify or follow the specimen. A pink label isn’t a universal, machine-readable identifier linked to patient and orders. Patient photographs aren’t part of standard lab traceability and raise privacy concerns, and they don’t integrate with the workflow to ensure correct specimen tracking.
