What should be done first if a biological sample is positive?

When a biological sample tests positive, the first crucial step is to document the results. This involves meticulously recording all relevant information about the test, including conditions under which the sample was collected, the specific results from the testing, and any observations made during the process. Documentation is vital as it provides a reliable record that can be referenced later, whether for further analysis, decision-making, or for legal and procedural purposes in a response operation.

Without proper documentation, the integrity of the testing process may be compromised, and important details could be lost, which can hinder further actions, such as confirming the presence of a biological threat.

Subsequent actions, such as evacuation, performing additional tests, or any mitigative measures, should be informed by the documented results. These steps rely on the accuracy and completeness of the recorded data to ensure a coordinated and effective response to the potential biological hazard.
