What are the results of field test kits?

Explanation:
Field test kits provide presumptive results. They’re designed for quick screening in the field and can indicate a probable presence of a substance, but they aren’t specific enough to confirm identity. Interferences, sample variability, and cross‑reactivity can affect the result, so a presumptive finding is typically followed by confirmatory laboratory testing to establish a definite identification.
