Blood Circulation Time
|
D001776 |
[Determination of the shortest time interval between the injection of a substance in the vein and its arrival at some distant site in sufficient concentration to produce a recognizable end result. It represents approximately the inverse of the average velocity of blood flow between two points.

|
Blood Coagulation
|
D001777 |
[The process of the interaction of BLOOD COAGULATION FACTORS that results in an insoluble FIBRIN clot.
] |
|
Blood Coagulation Disorders
|
D001778 |
[Hemorrhagic and thrombotic disorders that occur as a consequence of abnormalities in blood coagulation due to a variety of factors such as COAGULATION PROTEIN DISORDERS; BLOOD PLATELET DISORDERS; BLOOD PROTEIN DISORDERS or nutritional conditions.

|
Blood Coagulation Disorders, Inherited
|
D025861 |
[Hemorrhagic and thrombotic disorders that occur as a consequence of inherited abnormalities in blood coagulation.
] |
|
Blood Coagulation Factor Inhibitors
|
D019774 |
[Substances, usually endogenous, that act as inhibitors of blood coagulation. They may affect one or multiple enzymes throughout the process. As a group, they also inhibit enzymes involved in processes other than blood coagulation, such as those from the complement system, fibrinolytic enzyme system, blood cells, and bacteria.

|
Blood Coagulation Factors
|
D001779 |
[Endogenous substances, usually proteins, that are involved in the blood coagulation process.
] |
|
Blood Coagulation Tests
|
D001780 |
[Laboratory tests for evaluating the individual's clotting mechanism.
] |
|
Blood Component Removal
|
D001781 |
[Any procedure in which blood is withdrawn from a donor, a portion is separated and retained, at the same time the remainder is returned to the donor.
] |
|
Blood Component Transfusion
|
D016913 |
[The transfer of blood components such as erythrocytes, leukocytes, platelets, and plasma from a donor to a recipient or back to the donor. This process differs from the procedures undertaken in PLASMAPHERESIS and types of CYTAPHERESIS; (PLATELETPHERESIS and LEUKAPHERESIS) where, following the removal of plasma or the specific cell components, the remainder is transfused back to the donor.

|
Blood Culture
|
D000071997 |
[Test to determine the presence of blood infection (e.g. SEPSIS; BACTEREMIA).
] |
|
Blood Donors
|
D001782 |
|
|
Blood Flow Velocity
|
D001783 |
[A value equal to the total volume flow divided by the cross-sectional area of the vascular bed.
] |
|
Blood Gas Analysis
|
D001784 |
[Measurement of oxygen and carbon dioxide in the blood.
] |
|
Blood Gas Monitoring, Transcutaneous
|
D001785 |
[The noninvasive measurement or determination of the partial pressure (tension) of oxygen and/or carbon dioxide locally in the capillaries of a tissue by the application to the skin of a special set of electrodes. These electrodes contain photoelectric sensors capable of picking up the specific wavelengths of radiation emitted by oxygenated versus reduced hemoglobin.

|
Blood Glucose
|
D001786 |
[Glucose in blood.
] |
|
Blood Glucose Self-Monitoring
|
D015190 |
[Self evaluation of whole blood glucose levels outside the clinical laboratory. A digital or battery-operated reflectance meter may be used. It has wide application in controlling unstable insulin-dependent diabetes.
] |
|
Blood Group Antigens
|
D001789 |
[Sets of cell surface antigens located on BLOOD CELLS. They are usually membrane GLYCOPROTEINS or GLYCOLIPIDS that are antigenically distinguished by their carbohydrate moieties.
, The classification systems (or schemes) based on the different ANTIGENS located on ERYTHROCYTES.
] |
|
Blood Group Incompatibility
|
D001787 |
[An antigenic mismatch between donor and recipient blood. Antibodies present in the recipient's serum may be directed against antigens in the donor product. Such a mismatch may result in a transfusion reaction in which, for example, donor blood is hemolyzed. (From Saunders Dictionary & Encyclopedia of Laboratory Medicine and Technology, 1984).
] |
|
Blood Grouping and Crossmatching
|
D001788 |
[Testing erythrocytes to determine presence or absence of blood-group antigens, testing of serum to determine the presence or absence of antibodies to these antigens, and selecting biocompatible blood by crossmatching samples from the donor against samples from the recipient. Crossmatching is performed prior to transfusion.
] |
|
Blood Loss, Surgical
|
D016063 |
[Loss of blood during a surgical procedure.
