Field test kits provide what type of results?

• A. Presumptive
• B. Definitive
• C. Inconclusive
• D. No results

Answer: (A)

Field test kits are designed to give presumptive results, offering rapid screening in the field. A presumptive result indicates that the target substance or condition is likely present, but it is not a final, confirmatory identification. These tests are valued for speed, simplicity, and portability, often signaling presence with a color change or similar quick readout. Because they can be influenced by similar substances, contaminants, or environmental factors, they aren’t definitive. When a presumptive result is obtained, confirmatory testing in a controlled lab using more specific, validated methods is typically required to establish a definite result.
