| Question | Answer |
| State the reasons for a Quality Assessment Program | to ensure accuracy and validity of laboratory tests |
| Describe the preanalytic, analytic, and post analytic phases of quality assurance and give examples of each phase. | Pre-analytical – activities that occur before the sample reaches the lab
–Specimen collection issues, transport, preservatives used
Analytical – activities that occur in the lab and pertain to the analysis of the sample
–Test processing, QC data useful |

•College of American Pathologists |
| List the errors quality control aims to prevent. | random error: instrument, sample, human
systematic: accuracy of method, instrument, reagent decompostion |
| Define the following terms: quality assurance, quality control, accuracy, precision, calibration, control, standards, reference ranges, outliers, systematic error, random error, sensitivity and specificity | Quality assurance: attempts to control analytical errors
Quality control: refers to accuracy of method |

| Relate standard Deviations with corresponding percentage values in Gaussian curve and the use of these statistical equations in QC | |
| Calculate the following: mean, mode, median, coefficient of variation | |
| Recognize equation for standard deviation | |
| Analyze data to determine analytical error prevention | |
| Assess systematic and random errors and give examples of each. | |
| Discuss the use of controls in laboratory procedures | |
