Final answer:
When receiving PT samples from another lab for testing, one must adhere strictly to the lab's protocol for handling external samples to ensure the accuracy and integrity of the test results.
Step-by-step explanation:
When you receive PT (Proficiency Testing) samples from another lab for testing, you should follow the lab's protocol for handling external samples. Each laboratory should have a specific set of procedures and protocols for the receipt, handling, and testing of external samples to ensure consistency, accuracy, and safety. It is essential to adhere to these protocols to maintain the integrity of the samples and the validity of the test results. Do not discard the samples or store them for future use unless specified by the lab's protocol. Performing the tests immediately could also be incorrect if it does not align with the lab’s testing schedule or protocol requirements.
In general, protocols may include steps such as verifying the sample identity, logging the samples into a tracking system, storing the samples as required, and performing the tests according to the laboratory's standard operating procedures. Following these steps is crucial for ensuring that the results of the tests are accurate and reliable. Compare your results with those of others in your lab as a way of quality control and assurance that the samples were handled correctly.
