Answer to Question 1

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.

Answer to Question 2

ANS: C

When results are compared with those of another laboratory, this is part of external quality control. Internal quality control is done totally within one laboratory. Delta checks compare a patient result with a previous result on the same patient. Precision is determined by multiple analysis of the same specimen.
