Which of the following processes does not involve specimen integrity?

Specimen integrity is critical in the medical laboratory field as it ensures that the sample remains in a condition suitable for accurate testing. This includes factors such as how specimens are transported, stored, and tested.

Sample size determination refers to the process of deciding how much of a specimen is needed for testing to ensure results are valid and representative. While it is an important part of lab procedures and can affect various aspects of testing, it does not inherently impact the integrity of the specimen itself. Sample integrity focuses more on aspects such as contamination, degradation, or physical changes that might occur during transport, storage, or testing, rather than the volume of specimen taken.

In contrast, the other processes—transportation, storage conditions, and testing accuracy—are directly linked to preserving the quality and reliability of the specimen. Proper transportation methods, appropriate storage conditions, and accurate testing procedures all play crucial roles in maintaining specimen integrity, making any issues with them likely to compromise the reliability of laboratory test results.
