Which abbreviation expands to Test for narcotics?

• A. MARQUIS
• B. M.D.C.
• C. MEDICS
• D. MERZ

Answer: (A)

In drug screening, officers rely on quick chemical color tests to make a presumptive call about narcotics. The Marquis test is one of the oldest and most widely used for this purpose. It involves applying Marquis reagent (a mixture of formaldehyde and sulfuric acid) to a tiny sample; if narcotics are present, the sample develops a distinctive color. This color change helps indicate an opiate or other narcotic substance and prompts further confirmatory testing in the lab. Among the options, the Marquis test stands out as the standard, well-known test specifically used to detect narcotics, which is why it’s the best choice here. The other names listed aren’t recognized as the typical narcotics screening test.
