How do screening tests differ from confirmation tests when using the Intoxilyzer 8000?

Screening tests and confirmation tests serve distinct purposes in the analysis of blood alcohol concentration using the Intoxilyzer 8000. Screening tests are designed to quickly assess whether an individual's breath alcohol level exceeds a certain threshold that may indicate impairment. These tests can yield results rapidly and are often utilized in the preliminary stages of determining whether further testing is necessary.

In contrast, confirmation tests are conducted to provide more definitive results following a positive screening test. These tests are designed to confirm the presence of alcohol and provide a more precise measurement of the blood alcohol concentration. The results from confirmation tests are typically used in legal contexts, as they are considered more reliable and accurate compared to screening tests.

Understanding this distinction is essential, as it highlights the progressive nature of testing—screening tests serve as an initial filter, while confirmation tests offer a conclusive assessment that can be relied upon for legal or clinical decisions.
