clinical diagnosis a tentative diagnosis of a patients 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 for a specific 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 test 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 stablished 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 that remains after the solid elements and the clotting factor fibrinogen have been separated 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
