An example of a preanalytical (pre-examination) error is: Malfunction of a microprocessor that affects accuracy in testing Incorrect identification of a patient Transposition of a numeric critical value in transmitting a report Verbally reporting a laboratory result over the telephone 6. An example of an analytical (examination) error is: Malfunction of a microprocessor that affects accuracy in testing Incorrect patient identification Transposition of a numeric critical value in transmitting a report Use of the wrong anticoagulant in the patient sample tube 7. An example of a postanalytical (post examination) error is: Malfunction of a microprocessor that affects accuracy in testing Incorrect patient identification Transposition of a numeric critical value in transmitting a report Use of the wrong anticoagulant in the patient sample tube 8. Blood from the wrong patient is an example of a/an: Preanalytical (preexamination) error Analytical (examination) error Postanalytical (postexamination) error Either a or b 9. Specimen collected in the wrong tube is an example of a/an: Preanalytical (preexamination) error Analytical (examination) error Postanalytical (postexamination) error Either a or b 10. Quality control outside of acceptable limits is an example of a/an: Preanalytical (preexamination) error Analytical (examination) error Postanalytical (post examination) error Either a or c 11. Accuracy is defined as: How close results are to one another How close a test result is to the true value Specimen that is similar to patient’s blood; known concentration of constituent Comparison of an instrument measure or reading to a known physical constant 12. Calibration is defined as: How close results are to one another How close a test result is to the true value Specimen that is similar to patient’s blood; known concentration of constituent Comparison of an instrument measure or reading to a known physical constant 13. A control is defined as: How close a test result is to the true value Specimen that is similar to patient’s blood; known concentration of constituent Comparison of an instrument measure or reading to a known physical constant Measurement of a highly purified substance of known composition 14. Precision is defined as: How close results are to one another How close a test result is to the true value Comparison of an instrument measure or reading to a known physical constant Measurement of a highly purified substance of known composition 15. Standards are defined as: How close a test result is to the true value Specimens that are similar to patient’s blood; known concentration of constituent Comparison of an instrument measure or reading to a known physical constant Highly purified substances of known composition 16. Sensitivity is: Cases with a specific disease or condition that produce a positive result Cases without a specific disease or condition that produce a negative result Cases with a specific disease or condition that produce a negative result Cases without a specific disease or condition that produce a positive result 17. Specificity is: Cases with a specific disease or condition that produce a positive result Cases without a specific disease or condition that produce a negative result Cases with a specific disease or condition that produce a negative result Cases without a specific disease or condition that produce a positive result 18. The mean is: Another term for the average Most frequently occurring number in a group of values Number that is midway between the highest and lowest values A representation of a true analyte value 19. The median is: Another term for the average Most frequently occurring number in a group of values Number that is midway between the highest and lowest values A representation of a true analyte value 20. The mode is: Another term for the average Most frequently occurring number in a group of values Number that is midway between the highest and lowest values A representation of a true analytic value 21. The standard deviation is: Equal to SD divided by the mean Measure of variability The same as the mean value An exact measurement of an analytic value 22. The coefficient of variation is: Equal to SD divided by the mean Measure of variability The same as the mean value An exact measurement of an analytic value 23.

Today has been a typically busy day for her as she loads samples into instruments and checks results. Macy loaded two levels of quality control (QC) materials prior to a large run of patients and on checking the results for the QC, she noticed that one of the levels was outside the range that had been established. 24. What is Macy’s next step? Testing should be suspended until the issue is resolved. This depends on how far “out” the QC level is. There are a number of stat tests in the run, and she should report them “out.” She should repeat running the QC level that is out until it falls within range. As part of Macy’s investigation into the QC issue, she notices that a scheduled preventive maintenance (PM) activity was not performed yesterday. Macy completes the PM and then recalibrates the test that is having QC issues. After recalibration, the QC level is now in range. Macy documents the missed PM and her resolution within the binder kept with that machine. 25. Are Macy’s actions considered part of a quantitative QC program? No; a quantitative QC program involves the use of only two levels of control material for each day of testing. Yes; a quantitative QC program encompasses both equipment and reagents. No; the most important aspect of a quantitative QC program is the assurance of reliability. Yes; calibration is the most important part of a quantitative QC program.
