An example of a (pre-analytical ( pre-examination) error is):
Incorrect identification of a patient
An example of an analytical ( examination) error is:
Malfunction of a microprocessor that affects accuracy in testing
An example of a (post-s analytical ( post-examination) error is):

Specimen collected in the wrong tube is an example of a/an:
Pre-analytical ( pre-examination) error
Quality control outside of acceptable limits is an example of
Analytical ( examination) error
Proficiency testing is required by CLIA for:
Non-waived tests

Absolute change
Percent change
Rate of change
Quality control evaluate the ________ phase of testing
Analytical
Systematic error:
Is the most commonly encountered laboratory testing error
The “ Matrix” of a specimen
Has the components of a specimen other than the analyze of interest
More closely resembles the patient specimen
Accuracy is defined as:
How close a test result is to the true value
Calibration is defined as
Comparison of an instrument measurement or reading to a known physical constant.
A control is defined as
Specimen that similar to patients blood known concentration of constituent
Precision is defined as
How close results are to one another
Standards are defined as
Highly purified substances of known composition.
Sensitivity
Case with a specific disease or condition that produce a positive result
Specificity is
Case without a specific disease or condition that produce a negative result
The median is
Another term for the average
The median is
Number that is midway between the highest and lowest value
The mole is
Most frequency occurring number in a group of values
The standard deviation is
Measure of variability
The coefficient of variation is
Equal to SD divided by the mean
Total analytical error depends on
