What information should be documented when performing presumptive blood tests?

When performing presumptive blood tests, it is essential to document various pieces of information to ensure accuracy, accountability, and reproducibility of the results.

Documenting the date and time of the test is crucial as it establishes a timeline of the investigation, which can be important for understanding the sequence of events in a case and for maintaining the integrity of the evidence.

Including the name of the Crime Scene Investigator (CSI) conducting the test adds a layer of responsibility and accountability. It allows for tracking of the person who performed the test, which is vital for maintaining a chain of custody and ensures backtracking can occur if there are any questions or challenges regarding the results.

Recording the specific tests conducted provides detailed information about the methodologies used, which is important for evaluation and potential re-testing in the future. It also helps in assessing the reliability of the initial results and understanding the criteria under which the presumptive tests were performed.

Thus, documenting all of this information creates a comprehensive record that supports the integrity of the investigation and enhances the overall reliability of the findings.
