The linearity of an analytical procedure is its
Linearity ability (within a given range) to obtain test
results which are directly proportional to
the concentration (amount) of
analyte in the sample.
Accuracy A description of how close a measurement is
to the true value of the quantity measured.
Precision A measure of how close a series of measurements are
to one another.
Reliability Ability of a test to yield very similar scores for
the same individual over repeated testing.
Delta OD A process to detect discrepancies in patient
test results prior to reporting by comparing
current patient values to previous ones.
Coefficient of Variation A measure of relative variability computed by
(CV) dividing the standard deviation by the mean
and multiplying by 100.
Skewness A measure of the degree to which a distribution is
asymmetrical
Mean value A type of AVERAGE, found by adding up a set
of measurements then dividing by the
number of measurements.
Standard Deviation (SD) A measure of variability that indicates the
average difference between the scores and
their mean.
Shift A sudden change in the data mean that persists
throughout further days of testing.
Trend A general direction in which something is slowly
developing or changing
Prior to analysis - the phase where the

laboratory has no direct control on the
Preanalytical process. Preanalytical factors that can affect
results include: sample type,
sampling time, sample handling, patient's
preparation and the nutritional status of the
patient.
Postanalytical After analysis - recording the results,
interpreting the results, reporting the results to
the ordering physician, and filing the
report.
Confidence Limit Values greater than and less than the average,
between which the results are statistically
expected to fall a given percentage of the
time.
Normal distribution A function that represents the distribution of
variables as a symmetrical bell- shaped
graph.
Standard deviation index difference between the value of a data point
and the mean value divided by the group's
SD
Levey-Jennings chart a graph used to plot and visualize the results of
control samples over time
Difference between Accuracy: how close to accepted value
accuracy and Precision: how close together numbers are
precision
Total quality management (TQM) is a
Quality Improvement framework to operate and it is aiming for
(TQM)
integration, consistency, increase in
efficiency and a continuous drive for
improvement.
Focuses on processes/systems that contribute to
Quality Improvement patient, staff, or system
(CQI) outcomes. Goal is to maximize efficiency and
safety by addressing areas of improvement,
implementing changes based on data.
