Which tube is used for toxicology and trace elements testing?

• A. Tan tubes
• B. ACD tubes
• C. Royal blue tubes
• D. SPS tubes

Answer: (C)

For toxicology and trace elements testing, the key idea is to minimize any contamination that could skew metal measurements. Royal blue tubes are specifically manufactured to be trace-element free, making them the best choice when you’re analyzing trace metals or toxicology drugs, because they reduce the risk of introducing metals from the tube itself. They may contain an anticoagulant (like EDTA) or be additive-free, but either way their primary purpose is to avoid contamination. Tan tubes are typically used for lead testing, which is a type of toxicology, but they’re specialized for lead and not the general approach for a broad panel of trace elements. ACD tubes are intended for preserving cells for DNA and certain molecular tests, not for toxicology or metals analysis. SPS tubes are designed for blood cultures and some specialized assays and can contribute contaminants that interfere with trace element testing, so they’re not the right choice for these tests. So, royal blue tubes are chosen for toxicology and trace elements because they’re designed to minimize metal contamination, which is exactly what these tests require.
