AMT MLT EXAM UPDATED QUESTIONS
AND CORRECT ANSWERS.
Linearity - ANS The linearity of an analytical procedure is its ability (within a given range) to
obtain test results which are directly proportional to the concentration (amount) of analyte in
the sample.
Accuracy - ANS A description of how close a measurement is to the true value of the quantity
measured.
Precision - ANS A measure of how close a series of measurements are to one another.
Reliability - ANS Ability of a test to yield very similar scores for the same individual over
repeated testing.
Delta OD - ANS A process to detect discrepancies in patient test results prior to reporting by
comparing current patient values to previous ones.
Coefficient of Variation (CV) - ANS A measure of relative variability computed by dividing the
standard deviation by the mean and multiplying by 100.
Skewness - ANS A measure of the degree to which a distribution is asymmetrical

,Mean value - ANS A type of AVERAGE, found by adding up a set of measurements then
dividing by the number of measurements.
Standard Deviation (SD) - ANS A measure of variability that indicates the average difference
between the scores and their mean.
Shift - ANS A sudden change in the data mean that persists throughout further days of
testing.
Trend - ANS A general direction in which something is slowly developing or changing
Preanalytical - ANS Prior to analysis - the phase where the laboratory has no direct control on
the 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 - ANS After analysis - recording the results, interpreting the results, reporting
the results to the ordering physician, and filing the report.
Confidence Limit - ANS 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 - ANS A function that represents the distribution of variables as a
symmetrical bell-shaped graph.
Standard deviation index - ANS difference between the value of a data point and the mean
value divided by the group's SD

, Levey-Jennings chart - ANS a graph used to plot and visualize the results of control samples
over time
Difference between accuracy and precision - ANS Accuracy: how close to accepted value
Precision: how close together numbers are
Quality Improvement (TQM) - ANS Total quality management (TQM) is a framework to
operate and it is aiming for integration, consistency, increase in efficiency and a continuous
drive for improvement.
Quality Improvement (CQI) - ANS Focuses on processes/systems that contribute to patient,
staff, or system outcomes. Goal is to maximize efficiency and safety by addressing areas of
improvement, implementing changes based on data.
Spectrophotometry - ANS An analytical method for identifying a substance by its selective
absorption of different wavelengths of light.
Refractometry - ANS The method of measuring substances refractive index and assess their
composition or purity.
Turbidimetry - ANS A method of measuring the concentration of a substance by measuring
the amount of light passing through it
Osmometry - ANS The technique for measuring the concentration of dissolved solute
particles in a solution.
Chromatography - ANS A laboratory technique used to separate mixtures of molecules
