Which specimen handling practice helps preserve specimen integrity for most laboratory tests?

Maintaining specimen integrity relies on following the test’s specimen-handling requirements, including proper labeling, temperature control, and timely transport. Accurate labeling prevents mix-ups and ensures the right patient and test are matched throughout processing. Temperature control minimizes changes in the specimen that can alter results; some tests must be kept at room temperature, others refrigerated, and some require chilling or freezing to prevent degradation. Prompt transport reduces time-to-analysis, limiting processes like glycolysis or cellular breakdown that can skew results. Together, these practices protect the accuracy and reliability of laboratory measurements. Keeping specimens at room temperature regardless is not appropriate for all tests, since many require refrigeration or freezing to preserve the analyte. Randomly labeling after testing would defeat the purpose of correct identification and traceability. Freezing all specimens isn’t suitable for every test, as some analyses need fresh or specifically stored samples and improper freezing can damage certain components.
