NHA Phlebotomy-Technician Exam - Topic 1 Question 11 Discussion

When preparing a specimen for transport, the phlebotomist should keep the tube with the stopper upright whenever practical. Upright positioning helps reduce leakage risk, prevents specimen contact with the stopper area more than necessary, and supports safe handling during movement to the laboratory or processing area. Refrigerating infectious substances is not a universal transport rule; temperature requirements depend on the ordered test and specimen handling instructions. Agitating a tube vigorously is incorrect because it can cause hemolysis, clot disruption, foaming, or cellular damage. Additive tubes are mixed by gentle inversion according to manufacturer guidance, not shaking. Wrapping multiple tubes together is also poor practice because tubes should be protected from breakage, leakage, and cross-contamination using proper specimen transport bags, absorbent material when required, and separated compartments when applicable. Proper transport preserves analyte stability, patient safety, and biohazard control. NHA CPT processing content includes preparing specimens for testing or transport, maintaining specimen integrity based on temperature, light, or time requirements, and following handling, storage, transportation, and disposal requirements. Reference topics: Processing Specimens; specimen transport; tube handling; specimen integrity.
