Which drug test kit is used to initiate a sequential test on an unknown powdery substance?

• A. Mayers
• B. Scotts Modified
• C. Color Test Kit
• D. Marquis Reagent

Answer: (A)

The Mayers test is utilized to initiate a sequential test on an unknown powdery substance primarily because it is designed for detecting the presence of certain types of alkaloids and other compounds. This test operates based on a chemical reaction that produces a color change, allowing law enforcement officers to identify potential substances present in the sample. It is particularly useful in the preliminary identification stage, guiding further analysis through a sequential testing process. The significance of the Mayers test lies in its ability to provide initial information that can inform subsequent testing steps. By using this test first, officers can eliminate or narrow down substances, paving the way for more specific identification with additional tests. The Mayers test sets a foundation for a comprehensive analysis, which is critical in field investigations involving unknown substances.
