Calibration A mechanism to check the precision and accuracy of a test system, such as an automated analyzer, to determine if the system is providing accurate results. Calibration is typically performed using a calibration device, often called a standard.
Clinical diagnosis A tentative diagnosis of a patient's condition obtained through evaluation of the health history and the physical examination, without the benefit of laboratory or diagnostic tests.
Control A solution that is used to monitor a test system to ensure the reliability and accuracy of test results.
Fasting Abstaining from food or fluids (except water)for a specified amount of time before the collection of a specimen.
Homeostasis The state in which body systems are functioning normally, and the internal environment of the body is in equilibrium; the body is in a healthy state.
In vivo Occurring in the living body or organism.

Quality control The application of methods to ensure that results are reliable and valid and that errors are detected and eliminated.
Quantitative test A test that indicates the exact amount of a chemical substance that is present in the body, with the results being reported in measurable units.
Reagent A substance that produces a reaction with a patient specimen that allows detection or measurement of the substance by the test system.
Reference range A certain established and acceptable parameter or reference range within which the laboratory test results of a healthy individual are expected to fall.
Routine test A laboratory test performed routinely on apparently healthy patients to assist in the early detection of disease.
Serum The clear, straw-colored part of the blood (plasma) that remains after the solid elements and the clotting factor fibrinogen have been seperated out of it.
Specimen A small sample of something taken to show the nature of the whole.
Test system A setup that includes all of the test components required to perform a laboratory test such as testing devices, controls, and testing reagents.
Waived test A laboratory test that meets the CLIA criteria for being a simple procedure that is easy to perform and has a low risk of erroneous test results. Waived tests include tests that have been FDA-approved for use by patients at home.
