How does sample preservation affect toxicological analysis?
Sample preservation is crucial in toxicological analysis as it ensures the stability and integrity of the samples from the time of collection until analysis. Proper preservation prevents degradation or alteration of the toxicants, which could lead to inaccurate results. Various preservation methods, such as refrigeration, freezing, or chemical preservatives, may be used depending on the sample type and the analytes of interest. Maintaining a clear chain of custody is also essential to ensure the sample's integrity and traceability throughout the process.
