AMT MLT STUDY GUIDE LATEST 2025
Linearity - ANSWER- assumption that the best way to describe a pattern of data is
using a straight line
Accuracy - ANSWER- A description of how close a measurement is to the true value of
the quantity measured.
Precision - ANSWER- the exactness of a measurement
reliability - ANSWER- consistency of measurement
Delta OD - ANSWER- The optical density scan of amniotic fluid allows for the
assessment of bile pigments at 450 nm
coefficient of variation - ANSWER- Standard deviation divided by the mean
skewness - 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 - ANSWER- average
standard deviation - ANSWER- a measure of variability that describes an average
distance of every score from the mean
shift/trend - ANSWER- -when values start going one direction
-stay in that direction for a peroid of time
Pre & Postanalytical - 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 - ANSWER- The lower and upper scores defining the confidence
interval
, normal distribution - ANSWER- A function that represents the distribution of variables as
a symmetrical bell-shaped graph.
standard deviation index - 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 - 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 - ANSWER- the strategy for minimizing errors by managing each stage of
production
TQM (Total Quality Management) - ANSWER- Total Quality Management: A process
developed by Dr. W. Ed Deming to increase productivity through quality control
techniques.
CQI (continuous quality improvement) - ANSWER- A system of internal and external
reviews and audits of all aspects of an EMS system.
Proficiency Testing (PT) - 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 - ANSWER- Occupational Safety and Health Administration, a government
agency in the Department of Labor to maintain a safe and healthy work environment
CLIA - ANSWER- Clinical Laboratory Improvement Amendment-the law that regulates
human testing
HIPAA - ANSWER- The Health Insurance Portability and Accountability Act, a federal
law protecting the privacy of patient-specific health care information and providing the
patient with control over how this information is used and distributed.
laboratory safety - ANSWER- no drinking or eating in lab, wear safety equipment
(goggles and lab coat), keep flammable solutions away from flame, read lab instructions
before beginning lab, listen to directions, do not enter lab without teacher present, clean
up after yourself
