Why are 2 urine samples taken in EEK cases?

In cases involving EEK (Evidentially Required Knowledge) scenarios, taking two urine samples primarily serves the purpose of determining alcohol consumption levels. This practice is significant because alcohol can affect a person’s cognitive and physical abilities, which is critical information in legal and investigative contexts.

The first sample can be tested soon after collection for immediate results regarding the individual’s blood alcohol concentration (BAC). The second sample is kept as a reserve, which can be analyzed later if necessary. This ensures reliability and accuracy in determining the exact levels of alcohol in a person's system, especially in legal situations where evidence needs to be defendable or questioned in court.

Additionally, this method enables authorities to track changes in alcohol levels if investigations take longer, providing a clear insight into how a person's state might have affected their behavior or actions leading to an incident. Overall, the method of collecting two samples is a standard practice designed to uphold the integrity of the evidence regarding alcohol consumption.
