Final answer:
The PCT should collect the Lavender tube first.
Step-by-step explanation:
The order of blood collection is crucial for accurate test results. The Lavender tube is used for complete blood count (CBC), which includes various blood cell types and their counts. CBC is a common and important test, providing valuable information about a patient's overall health. By collecting the Lavender tube first, the PCT ensures that the CBC is prioritized, allowing for timely analysis of essential blood cell parameters. This decision aligns with the logical sequence of sample collection, optimizing the workflow in the laboratory.
Different tubes are designed for specific tests, and each has an additive that preserves the blood sample for accurate analysis. In this case, the Lavender tube contains the anticoagulant EDTA, preventing blood clotting and preserving the integrity of cell counts. Blood cultures, on the other hand, are typically collected in Yellow tubes, as they contain a culture medium to support the growth of microorganisms. By following the correct order, the PCT minimizes the risk of cross-contamination and ensures the reliability of both CBC and blood culture results.
It's important to prioritize patient safety and sample quality in healthcare procedures. Understanding the rationale behind the sequence of tube collection reflects the PCT's commitment to delivering precise and reliable laboratory results. This adherence to best practices contributes to the overall effectiveness of patient care and diagnostic processes.
