To ensure confidence in test results, samples must be properly:

To ensure confidence in test results, it is essential that samples are properly collected. The collection process is critical because it directly impacts the integrity and representativeness of the sample. If samples are not collected correctly, it can lead to contamination, degradation, or misrepresentation of the data being analyzed. Proper collection techniques, including the use of appropriate containers, aseptic methods, and following standard protocols, ensure that the samples truly reflect the conditions being studied and yield reliable outcomes.

While analyzing, displaying, and documenting samples are also important steps in the testing process, they follow the initial collection stage. Any inconsistencies in the collection will invalidate all subsequent steps, rendering the analysis, display, or documentation ineffective. Therefore, establishing confidence in test results fundamentally begins with proper sample collection.
