What is PT testing?
CLIA approved Proficiency Testing programs allow laboratories to evaluate their performance on a regular basis; usually 2 to 3 times a year. These programs also allow laboratories to improve the accuracy of the patient results they provide.
If proficiency specimens are not commercially available (most commonly seem in molecular testing)
vLaboratories can exchange blind split samples
vBlinded samples are measured or documented by independent means such as chart review
HEALTH INSURANCE PORTABILITY AND ACCOUNTABILITY ACT OF __

Who inspects Certificates of Accreditation?
A CMS-deemed professional organization, not CMS directly.
What are the requirements for testing personnel

Quality Control (QC)
uis the process by which one monitors analytical procedures in order to ensure the accuracy and precision of test results and thus the validity of patient results prior to their reporting
Quality control is accomplished by
monitoring QC materials such as serum, urine, and CSF alongside with patient samples
Internal QC involves the following:
Monitoring control results over time for changes in precision (random error) or accuracy (systematic error)
External QC involves the following
The comparison of a lab's assay results from unknown test samples with the mean results of those obtained on the same samples by other labs
QC material is prepared by
pooling either human or animal source body fluids.
Lot Switch
uIt is good practice to assay an old lot number of control alongside a new lot number of control when first using it.
Hospitals run levels of controls per ____
shift change, per instrument or batch run
Accuracy
a measure of how closely a test result agrees with the "true" value for that sample
Precision
A measure of how closely repeated measurement of a sample (replicates) agree with each other
Imprecision
Measurements do not closely replicate, and the SD will be larger
Reliability
A measure of both the accuracy and precision of a method
Central Tendency
Represents a large group of data points that are equal to or very nearly the same as one data point (cluster of data points) and are represented by a peak on a frequency diagram
Normal or Gaussian Distribution
Implies that there are approximately the same number and distribution of data points to either side of the peak (bell-shaped curve). Mean, median, and mode are approximately equal values
Mode
the most frequent number or value found in a data set.
Range
the difference between the high and low values of data in a data set.
Variance
A mathematical representation of the dispersion or degree of tightness of data points around the mean or peak in a data set. It is the square of the SD
Variance Formula (population)
Standard Deviation
the mathematical representation of the dispersion or degree of tightness of data points around the mean or peak in a data set. It is easily calculated by taking the square root of the variance
Confidence Interval (CI)
refers to the limits (high and low) between which a specified proportion of the data points in a data set will fall.
68% CI = mean +/- 1 SD
95% CI = mean +/- 2 SD
99% CI = mean +/- 3SD
Coefficient of Variation
the SD divided by the mean and multiplied by 100 to obtain a percentage.
% CV = SD/mean (100)
Levey-Jennings Charts
An approach to monitoring method performance for precision and long term accuracy
Trend
A small but steady and continuous change of the control values on one direction.
Often indicate reagent or calibrator deterioration or gradual instrumental failure
Shift
A change of the mean for the control material.
New mean is continuous but different from the original mean
Can be caused by resetting an instrument, a small but consistent flaw in the instrument, or a change of lot number of control
95% rule
Rule of thumb; the control value should fall within +/- 2 SD (95%) of the mean
Imprecision
large amount of scatter about the mean. Usually caused by errors in technique
Inaccuracy
may see as a trend or a shift, usually caused by change in the testing process
Random error
= no pattern. Usually poor technique, malfunctioning equipment
Westgard rules
"Multirule Quality Control"
Uses a combination of decision criteria or control rules
Allows determination of whether an analytical run is "in-control" or "out-of-control"
