Quality Control Flashcards
This stage of laboratory testing deals with sample, reagent, and supply preparation.
Pre-analytical
The stage where the unknown specimen are analyzed, instruments are set to 0 (blank), standard references are checked, and control is done.
Analytical
This is the stage where data gathered is computed.
Post-Analytical
Encompasses all phases of analytical testing
Quality Assurance
Focuses on the analytical phase
Quality Control
Accuracy vs. Precision
Accuracy - Closeness or nearness of value to standard.
Precision - Closeness or proximity of results to each other
Sensitivity
High sensitivity tests refer to tests that are cooperative even when only a minute or a small concentration of the analyte is given.
Specificity
Tests that can measure only one analyte.
Practicality
Analysis should be easy to carry out
This QC tool is from the patient to be analyzed
unknown specimen
This is used in comparison with the unknown using beer’s law
Standard
Action of setting the instrument reading to 0
blank
These reference range are Pre-analyzed and used for the analysis of the unknown.
Control
The occurrence of Random Errors
once
This type of error is achieved when the error is done more than once.
Systematic Error
