QuestionAnswer
How close a test result comes to the true value of the substance being measured is it's: accuracy
A substance that is tested for in the laboratory procedure for its presence or quantity in a patient or control sample is an: analyte
the skewing of test results away from the true value is known as: bias
The testing and adjusting of an instrument is called: calibration
testing calibrators in the same manner as patient specimens to ensure accuracy of results is: calibration verification
A solution of an analyte obtained from a manufacturer used as a measuring stick to set instruments ro read results correctly are: calibrators
The certificate issued to a lab in which a physician, mid-level practitioner, or dentist performs microscopy is: PPMP, Certificate for provider performed microscopy procedures
A certificate issued to a lab on the basis of the lab's accreditation by an accreditation organization approved by the health care financing administration is: Certificate of accreditation
A certificate issued to a lab after an inspection finds the lab to be in compliance with all CLIA requirements is: certificate of compliance
A certification issued to a lab that enables the entity to conduct moderate or high complexity lab testing until the lab is determined to be in compliance with CLIA regulations is: certification of registration
This certification allows a lab to only perform waived tests: certification of waiver
a sample used to maintain accuracy and quality in a procedure is a: Control
A chart on which control values are plotted daily giving an easily assessment of the normalcy of the test results is: Levey-Jennings chart
A measure of an instrument's ability to measure test results in an accurate manner is: linearity
tests with more complicated steps and procedures in which the risk of erroneous results is higher is a: nonwaived test
The description given to a quality system when test results are beyond the upper or lower limits of the acceptable range is know as: out of control
The ability to repeatedly get the same results is: precision
a quality control sample that is of the highest possible quality and accuracy is a: primary standard
A component of the quality control system that tests the accuracy of lab procedures and staff is: proficiency testing
A set of policies implemented to give patients the very best medical care possible covering all aspects of medical care is: quality assessment
Any measure that ensures consistent lab procedures and accurate test results is: quality control, QC
All of the labs policies, processes, procedures, and resources needed to achieve quality testing is: quality system
unpredictable errors with no obvious pattern is: random errors
Normal or expected values or range that covers 95% of normal, healthy, individuals is called: reference range
the accuracy and precision of a testing procedure or instrument is: reliability
the ability to repeat test results is known as: reproducibility
a quality control sample manufactured and analyzed to very exact measurements is called: standard
A measurement of the variation from the mean in sample of values is: standard deviation
a noticeable pattern of errors is: systematic errors
The value given by the manufacturer of a quality control sample as the expected quality control results are the: Target value
The value for a test result that is based on the results obtained from the best qualified labs using the purest reagents, refined methods, and best technology is: True value or gold standard
The ability of a test to determine those who have a specific decease or condition and those who do not is: validity
the tendency for objects and procedures to change or deviate from the standard is known as: variability
defined by CLIA as simple lab examination and procedures that have an insignificant risk of erroneous results: waived testing
