What is the purpose of cold packs in a phlebotomy setting?

The purpose of cold packs in a phlebotomy setting is to preserve samples that require refrigeration. Certain blood samples must be kept at lower temperatures to maintain their integrity and prevent degradation until they can be analyzed in the laboratory. Cold packs help maintain the required temperature for such samples, ensuring accurate test results.

In various laboratory testing scenarios, temperature sensitivity is critical; for example, some metabolic tests or hormone levels can change if the samples are not kept cool. This practice is essential for ensuring the reliability of the results when the samples are later analyzed. It is important for phlebotomists to understand the specific requirements for each type of sample to ensure proper handling and storage.
