The best way to prevent errors in the laboratory is to ensure:

a. Purchasing quality instruments from reputable vendors
b. Hiring only well-trained, conscientious workers
c. Having quality management
d. Performing external quality control procedures


ANS: B
Only well-trained, conscientious clinical laboratory personnel can ensure that the best quality results are routinely obtained for patients. A quality instrument is only as good as it is correctly calibrated and maintained. Management, although ultimately responsible, relies on the laboratory personnel to be aware of potential problems in assays. External quality control programs do not guarantee the daily validity of patient results.
