Maintaining specimen integrity ensures that the sample remains in its original condition, free from contamination, degradation, or changes that could affect the test results. This includes factors such as proper handling, storage conditions, and transport measures taken to protect the specimen.

When specimen integrity is upheld, it leads to reliable and accurate testing outcomes, which are essential for diagnosing and monitoring health conditions. This is why the option that focuses on the preservation of a specimen's state is the most appropriate answer regarding what specimen integrity refers to in laboratory testing.
