What is the correct use for royal blue tubes with lavender stripes?

Royal blue tubes with lavender stripes are specifically designed for heavy metal toxicology tests. These tubes are manufactured to minimize contamination from trace elements that could interfere with testing results. They are often used when testing for metals such as lead, mercury, and arsenic, as accurate measurements are critical for effective diagnosis and treatment.

The design of these tubes ensures that the samples collected remain free from metals that could be present in other tube types due to their production materials. This makes them particularly valuable in toxicology, where precision in measurement is essential.

In contrast, other tube colors or types are better suited for different tests. For example, tubes used for routine hematology tests typically have different additives or colors that are tailored for such analyses, and tubes designed for blood gas analysis focus on maintaining the sample's pH and gas levels, which is not the focus for royal blue tubes. Thus, the selection of royal blue tubes with lavender stripes for heavy metal tests is critical to obtaining accurate and reliable results in toxicology.
