Study Set | High-Yield Notes, Questions &
Explanations
Linearity - correct answer-assumption that the best way to describe a pattern of
data is using a straight line
Accuracy - correct answer-A description of how close a measurement is to the
true value of the quantity measured.
Precision - correct answer-the exactness of a measurement
reliability - correct answer-consistency of measurement
Delta OD - correct answer-The optical density scan of amniotic fluid allows for the
assessment of bile pigments at 450 nm
coefficient of variation - correct answer-Standard deviation divided by the mean
,skewness - correct answer-to a distortion or asymmetry that deviates from the
symmetrical bell curve, or normal distribution, in a set of data. If the curve is
shifted to the left or to the right, it is said to be skewed.
mean value - correct answer-average
standard deviation - correct answer-a measure of variability that describes an
average distance of every score from the mean
shift/trend - correct answer--when values start going one direction
-stay in that direction for a peroid of time
Pre & Postanalytical - correct answer-pre-analytic testing phase occurs first in the
laboratory process. This phase may include specimen handling issues that occur
even prior to the time the specimen is received in the laboratory.
post-analytic phase is the final phase of the laboratory process. This phase
culminates in the production of a final value, result, or in the case of histology, a
diagnostic pathology report.
confidence limits - correct answer-The lower and upper scores defining the
confidence interval
normal distribution - correct answer-A function that represents the distribution of
variables as a symmetrical bell-shaped graph.
, standard deviation index - correct answer-a measurement of bias. The target SDI
is 0.0, which indicates that there is no difference between the laboratory mean
and the consensus group mean.
Levey-Jennings charts - correct answer-a graph that quality control data is plotted
on to give a visual indication whether a laboratory test is working well. The
distance from the mean is measured in standard deviations
quality control - correct answer-the strategy for minimizing errors by managing
each stage of production
TQM (Total Quality Management) - correct answer-Total Quality Management: A
process developed by Dr. W. Ed Deming to increase productivity through quality
control techniques.
CQI (continuous quality improvement) - correct answer-A system of internal and
external reviews and audits of all aspects of an EMS system.
Proficiency Testing (PT) - correct answer-a program in which a laboratory's
accuracy in performing analyses is evaluated at regular intervals and compared to
the performance of similar laboratories
OSHA - correct answer-Occupational Safety and Health Administration, a
government agency in the Department of Labor to maintain a safe and healthy
work environment
CLIA - correct answer-Clinical Laboratory Improvement Amendment-the law that
regulates human testing
