CORRECT ANSWERS) ALREADY GRADED A+
Sensitivity equation - CORRECT ANSWER-TP/(TP+FN)
For a qualitative test, sensitivity is determined by... -
CORRECT ANSWER-The number of true positives divided by
all results that should have been positive
Predictive value for a negative qualitative test - CORRECT
ANSWER-NPV = TN/(TN+FN)
,NPV is best described as... - CORRECT ANSWER-The
number of true negative values divided by all observed
negative values
Precision is viewed as what statistic in clinical chemistry? -
CORRECT ANSWER-Standard deviation
Accuracy is viewed as what statistic in clinical chemistry? -
CORRECT ANSWER-Mean
Specificity equation - CORRECT ANSWER-TN/(TN+FP)
For a qualitative test, specificity is determined by... -
CORRECT ANSWER-The number of true negatives divided by
all results that should have been negative
What are the key parameters for a qualitative test? -
CORRECT ANSWER-Specificity, sensitivity, predictive value,
and accuracy
,What are the key parameters for quantitative test? -
CORRECT ANSWER-Accuracy, precision, reference range,
and critical values
Ion-selective electrodes (ISE) can be used to measure
analytes including... - CORRECT ANSWER-pH, Na, Cl, CO2, K
What is an amount of enzyme that catalyze the conversation
of one micromole of substrate in 1 minute? - CORRECT
ANSWER-International unit
Enzyme-based clinical assays can measure what two things? -
CORRECT ANSWER-Endogenous enzymes and endogenous
substrates
UV/Visible absorbance assays rely on what to determine the
concentration of an analyte in solution or samples? -
CORRECT ANSWER-The Beer-Lambert Law
, What does nephelometry measure? - CORRECT ANSWER-It
measures the scatter of light by particles (light scattering of
the sample/the stability of the sample)
What does refractometry measure? - CORRECT ANSWER-
Light bending as it passes through different media
Why is LC/MS more selective than LC/UV? - CORRECT
ANSWER-MS can determine molecular weight, detect novel
substances, and has high mass accuracy.
What type of test is most often available over the counter
for home pregnancy test? - CORRECT ANSWER-
Immunochromatographic assay
What hormone is most likely to interfere with a home
pregnancy test? - CORRECT ANSWER-Follicle stimulating
hormone (FSH)
(T/F) Hospital/clinical laboratories tend to have a higher
degree of automation to handle high volumes of samples,
