What is the term used for a sample that appears positive but requires further analysis before a final result can be reported?

The term "presumptive positive" refers to a situation where initial test results indicate a positive finding, but these results need to be verified through additional testing before a definitive conclusion can be reached. This terminology is commonly used in various testing scenarios, including those involving food safety and inspection, to convey that while there is a reasonable suspicion of a positive result, it is not yet confirmed.

This approach is critical in inspections as it helps prevent premature conclusions that could lead to unnecessary actions or misunderstandings. Confirming the result through follow-up analyses ensures reliability and accuracy in reporting, which are essential in maintaining food safety standards and implementing proper regulatory practices.

The other terms listed, while relevant in different contexts, do not accurately denote the preliminary nature of a test signal requiring further validation.
