What are potential indicators that a donor might try to adulterate a specimen?

The presence of unusual equipment or substances is a strong indicator that a donor might attempt to adulterate a specimen. When someone arrives with atypical items that are not standard for a urine test, it suggests the possibility of tampering with the sample. This could include items such as specific chemicals, heating pads, or other materials that could be used to alter the integrity of the urine sample or mask the presence of certain substances.

In contrast, asking numerous questions about the procedure might stem from a donor's desire for clarification rather than intent to adulterate. Similarly, conversing easily with the collector could indicate a relaxed or comfortable demeanor rather than suspicious behavior. Being punctual for the test generally shows compliance and willingness to undergo the testing process, which does not suggest an attempt to tamper or adulterate the specimen.
