Quality Control Flashcards
Measures smallest concentration of analyte
Sensitivity
Measure only analyte of interest
Specificity
This study determines how much of an analyte can be identified in the sample
Recovery study
This study determines if specific compounds affect lab tests
Interference study
This study is used to assess presence of error/inaccuracy in actual patient sample
Sample comparison
Accuracy uses 3 types of study
Recovery study
Interference study
Sample comparison study
Give repeated results that agree with one another
Precision
Precision is also known as
Reproducibility
The newrness or closeness of the assayed value to the true/target value
Accuracy
Reliability
Ability of analytical methid to maintain accuray and precision over an extended period of time during which equipment, reagents and personel may change
Detect proportion of individuals with the disease
Diagnostic sensitivity
Detect proportion of individuals without the disease
Diagnostic specificity
Used in confirmatory tests
Diagnostic specificity
Used in Screening tests
Diagnostic sensitivity
Analytical run
The set of control and patient sample tested, evaluated and reported together
