Fertilization in Vitro definition: An assisted reproductive technique that includes the direct handling and manipulation of oocytes and sperm to achieve fertilization in vitro.
artificial fertilization definition: assisted reproductive technique that includes the direct handling and manipulation of oocytes and sperm to achieve fertilization in vitro.
in vitro fertilization definition: a process whereby (usually multiple) ova are placed in a medium to which sperm are added for fertilization, the zygote thus produced is then introduced in the uterus.
in vitro fertilization definition: A procedure in which eggs are removed from a woman's ovary and combined with sperm outside the body to form embryos. The embryos are grown in the laboratory for several days and then either placed in a woman's uterus or cryopreserved (frozen) for future use.
In Vitro definition: Studies using excised tissues.
organ culture definition: technique for maintenance or growth of animal organs in vitro; refers to three-dimensional cultures of undisaggregated tissue retaining some or all of the histological features of the tissue in vivo.
Organ Culture Techniques definition: A technique for maintenance or growth of animal organs in vitro. It refers to three-dimensional cultures of undisaggregated tissue retaining some or all of the histological features of the tissue in vivo. (Freshney, Culture of Animal Cells, 3d ed, p1)
Organ Culture definition: The maintenance or growth of tissues, organ primordia, or the parts or whole of an organ in vitro in such a way as to allow differentiation or preservation of the architecture or function.
Reagents definition: Substances intended to detect and/or measure, in some cases producing or modifying other substances, a specific analyte of interest (e.g., enzymes, hormones). Substances used as reagents must be sufficiently pure to appropriately perform a specific analytical test. Reagents are typically used in the clinical laboratory for clinical chemistry, immunochemistry, hematology, microbiology (e.g., culture), infectious immunology, and molecular biology (e.g., nucleic acid technology) tests.
Reagent definition: A chemical that has general laboratory application and that is not labeled or otherwise intended for a specific application. General purpose reagents include cytological preservatives, decalcifying reagents, fixatives and adhesives, tissue processing reagents, isotonic solutions, and pH buffers.
Oximeters, In Vitro definition: Oximeters used for determining the oxygen saturation in arterial blood (SpO2) and hemoglobin forms in blood samples. The operation of these oximeters is based in measuring the light intensity that passes through a blood sample at different wavelengths, either using photometric or spectrophotometric techniques. In vitro oximeters are used in central clinical laboratories and also in surgical area and critical care units.
Oximeters, In Vitro, Laboratory definition: Oximeters that can be used for the simultaneous determination of hemoglobin forms, such as oxyhemoglobin (O2Hb), deoxyhemoglobin (HHb), reduced hemoglobin (RHb), carboxyhemoglobin (COHb), methemoglobin (MetHb), and the sum of all hemoglobin derivatives (total hemoglobin, tHb). The operation of these oximeters is based in measuring the light intensity that passes through a blood sample at several different wavelengths (usually four or more). The wavelengths are selected either by a filter wheel (photometric technique) or a diffraction grating (spectrophotometric technique). From these measurements these instruments calculate oxygenation derivatives, including oxygen saturation, content, and capacity. Laboratory oximeters are used in central clinical laboratories, cardiac catheterization suites, surgical suites, and critical care units.
in vitro Sensitivity-Directed Chemotherapy definition: Uses the results of a chemosensitivity testing assay to tailor the treatment to the individual.
SYSTEM, MULTIPURPOSE FOR IN VITRO COAGULATION STUDIES definition: A multipurpose system for in vitro coagulation studies is a device consisting of one automated or semiautomated instrument and its associated reagents and controls. The system is used to perform a series of coagulation studies and coagulation factor assays.
MEDIA, POTENTIATING FOR IN VITRO DIAGNOSTIC USE definition: Potentiating media for in vitro diagnostic use are media, such as bovine albumin, that are used to suspend red cells and to enhance cell reactions for antigen-antibody testing.
CENTRIFUGE, BLOOD-BANK FOR IN VITRO DIAGNOSTIC USE definition: A blood bank centrifuge for in vitro diagnostic use is a device used only to separate blood cells for further diagnostic testing.
SUBSTANCE, BLOOD GROUPING OF NON-HUMAN ORIGIN FOR IN VITRO DIAGNOSTIC USE definition: Blood group substances of nonhuman origin for in vitro diagnostic use are materials, such as blood group specific substances prepared from nonhuman sources (e.g., pigs, cows, and horses) used to detect, identify, or neutralize antibodies to various human blood group antigens. This generic type of device does not include materials that are licensed by the Center for Biologics Evaluation and Research of the Food and Drug Administration.
Oximeters, In Vitro, Point-of-Care definition: Oximeters designed for determination of only a small number of critical parameters (e.g., oxygen saturation, total hemoglobin) at the point of Care. These oximeters use smaller whole-blood samples and are simpler to operate than laboratory oximeters, while producing fast and reasonably accurate results. Point-of-care oximeters are used in sites such as surgical suites, cardiac catheterizations areas, critical care rooms, and the patient's bedside.
ASSAY, PROLIFERATION, IN VITRO, T LYMPHOCYTE definition: A device measuring the constituents of deviding DNA or other pre-division cellular constituents to classify the ability of T lymphocytes (a type of normal white blood mononuclear cell) to divide or proliferate in response to specific or non-specific added stimulants. The T lymphocytes may be normal in number or abnormally low in number due to a natural or induced immunosuppressed state in the patient.
Primary Cell Culture definition: The cells taken from a tissue source, and their progeny, grown in culture before subdivision and transfer to a sub culture.
Bioassay, in vitro definition: A laboratory test or analysis of the biological activity of a substance performed by studying its effect in an experimental situation outside the organism, e.g. in the test tube rather than in living systems.
Culturing, in vitro Invertebrate definition: Maintenance of invertebrate tissue after removal from the body, by placing in a vessel with a sterile nutritive medium.
Culturing, in vitro Microbial definition: The growing of microbes in test tube or petri dish type environments
Culturing, in vitro Vertebrate, Cell definition: Propagation of vertebrate animal cells in culture.
Culturing, in vitro Vertebrate, Tissue definition: Maintenance of vertebrate tissue after removal from the body, by placing in a vessel with a sterile nutritive medium.
in vitro Assay definition: Assay conducted in an artificial environment, such as in a test tube, under a defined and controlled set of solvent and solute conditions.
in vitro definition: In the laboratory (outside the body). The opposite of in vivo (in the body).
in vitro definition: In the laboratory; literally, "in glass".
