Quizplus · Accepted Answer

Using specially manufactured collection tubes with unique stoppers is critical for blood collection for trace metal analysis. These tubes prevent contamination of the sample by trace metals from the stopper, which could interfere with the accuracy of the analysis. Timing of the blood draw, type of specimen (serum vs. plasma), and tourniquet use can also impact the accuracy of trace metal analysis, but using specialized tubes with appropriate stoppers is the most critical factor.
