| Homeostasis | 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. |
| Profile / Panel | Array of laboratory tests for identifying a disease state or evaluating a particular organ or organ system. Tests that are RELATED. |
| Product insert | Printed document supplied by the manufacturer with a laboratory test product that contains information on the proper storage and use of the product. |
| Control | Solution that is used to monitor a test system to ensure the reliability and accuracy of the test results. |
| Qualitative test | Test that indicates whether a substance is present in the specimen being tested and provides an approximate indication of the amount of the substance present. |
| Quality control | Application of methods to ensure that test results are reliable and valid and that errors are detected and eliminated. |
| In vivo | Occurring in the living body or organism. |
| Quantitative test | Test that indicates the exact amount of a chemical substance that is present in the body, with the results being reported in measurable units. |
| Analyte | Substance that is being identified or measured in a laboratory test. |
| Reagent | 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 of reference range within which the laboratory test results of a healthy individual are expected to fall. |
| Clinical diagnosis | Tentative diagnosis of a patient's condition obtained through the evaluation of the health history and the physical examination, without the benefit of laboratory of diagnostic tests. |
| Fasting | Abstaining from food or fluids (except water) for a specified amount of time before the collection of a speciam. |
| Waived test | 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. |
| Routine test | Laboratory test performend routinely on apparently healthy patients to assist in the early detection of disease. |
| Serum | Clear, straw-colored part of the blood (plasma) that remains after the solid elements and the clotting factor fibrinogen have been separated from it. |
| Calibration | Mechanism to check the precision and accuracy of a test system, such as an automated analyzer. |
| Specimen | Small sample of something taken to show the nature of the whole. Patient's sample. |
| Laboratory test | Clinical analysis and study of materials, fluids, or tissues obtained from patients to assist in diagnosis and treatment of disease. |
| Test system | Setup that includes all of the test components required to perform a laboratory test such as testing devices, controls, and testing reagents. |
| Nonwaived test | Complex laboratory test that does not meet the CLIA criteria for waiver and is subject to the CLIA regulations. |
