Regular review of blood specimen collection quality is an example of:

The correct answer, preanalytical quality assurance, refers to the processes and considerations that take place before the analysis of blood specimens. This includes the proper collection techniques, handling, and preparation of samples. Regularly reviewing blood specimen collection quality ensures that the samples are not compromised due to issues such as improper collection, transport, or storage, which can lead to inaccurate test results.

Preanalytical quality assurance encompasses various factors, including the training of personnel in specimen collection, appropriate use of collection tubes, and adherence to protocols that minimize the risk of contamination or degradation of the samples. By maintaining high standards in this phase, laboratories can ensure that the samples sent for analysis yield reliable and accurate results.

This contrasts with the other concepts listed. Postanalytical quality assurance focuses on processes that take place after the analysis has been completed, such as result reporting. Analytical quality control involves the procedures and controls that are performed during the testing of the specimen itself to ensure accuracy and consistency in results. External quality assurance typically refers to outside assessments or proficiency testing that evaluate the overall quality and reliability of a laboratory's testing processes rather than the specific processes of collection quality.
