Why might some samples be identified with only a number upon submission to a laboratory?

When samples are identified with only a number upon submission to a laboratory, the primary purpose is to ensure unbiased analyses by the technicians. This practice helps to eliminate any potential bias that may arise from personal biases, preconceived notions, or familiarity with the sample donors. By using a numerical identifier, the laboratory technicians focus solely on the sample itself and its properties, rather than any external factors that might influence their analysis or interpretation of the results.

This approach fosters an environment of objectivity and accuracy, which is crucial in scientific analyses and testing. It helps to uphold the integrity of the laboratory results by ensuring that each sample is treated equally without any personal influence. Maintaining anonymity through numerical identification is a standard practice in various testing environments to promote fair and equitable assessments.

While quicker processing, maintaining records, and tracking results are important considerations in laboratory operations, the key focus in this scenario is on eliminating bias to uphold the credibility of the analyses.
