What is the correct approach to storing and transporting collected specimens?

• A. Transport specimens immediately at room temperature regardless of test type
• B. Follow specimen-specific storage and transport requirements, maintain temperature, and ensure timely delivery
• C. Leave specimens at bedside until lab requests them
• D. Freeze all samples regardless of type

Answer: (B)

Preserving specimen integrity from collection to analysis requires handling each sample according to test-specific storage and transport rules. Different tests depend on the stability of particular analytes, preservatives, and components of the specimen. Some must be kept cold, others at room temperature, some protected from light, and some require specific anticoagulants. Following the lab’s guidelines ensures the sample remains stable long enough to yield accurate results and that any delays or mishandling don’t alter the measurements. Transport should also be timely. Delays can allow metabolic changes, enzymatic activity, or deterioration that skews results or necessitates recollection. Packaging and labeling must meet the lab’s requirements to maintain the chain of custody and prevent contamination or misidentification. Transporting every specimen at room temperature regardless of test type risks degradation for many tests. Leaving specimens at bedside can lead to contamination, mislabeling, or delays. Freezing all samples ignores those tests that require fresh or specific room-temperature handling and can itself alter results for many assays.
