|---|---|
| Analyte | A substance that is being identified or measured in a laboratory test. |

| 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. |
| Laboratory test | The clinical analysis and study of materials, fluids, or tissue obtained from patients to assist in diagnosis and treatment of disease. |
| Nonwaived test | A complex laboratory test that does not meet the CLIA criteria for waiver and is subject to the CLIA regulations. |
| Plasma | The liquid part of the blood, consisting of a clear, yellowish fluid that comprises approximately 55% of the total blood volume. |

| 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. |
