| blood catecholamine | <investigation> The measurement of noradrenaline and adrenaline in the blood. Often these same catecholamines can be measured in the urine. Elevations may be seen in pheochromocytoma or neuroblastoma. Normal blood levels of adrenaline should be: 20 ng/ml and normal blood levels of noradrenaline should be 60 ng/ml. (05 Jan 1998) |

| blood cell | <haematology> There are three main types of cell in the blood stream. The red cell, which carries oxygen, the white cell, which fights infections and the platelet, which helps prevent bleeding. The correct balance between each cell type must be maintained for the body to remain healthy. (13 Nov 1997) |
| blood cell count | A count of the number of leukocytes and erythrocytes per unit volume in a sample of venous blood. A complete blood count (cbc) also includes measurement of the haemoglobin, haematocrit, and erythrocyte indices. (12 Dec 1998) |
| blood-cerebrospinal fluid barrier | A barrier located at the tight junctions which surround and connect the cuboidal epithelial cells on the surface of the choroid plexus; capillaries and connective tissue stroma of the choroid do not represent a barrier to protein tracers or dyes. (05 Mar 2000) |
| blood circulation | The course of the blood from the heart through the arteries, capillaries, and veins back again to the heart. (05 Mar 2000) |
| blood circulation time | 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. (12 Dec 1998) |
| blood clot | <haematology> The conversion of blood from a liquid form to solid through the process of coagulation. A thrombus is a clot which forms inside of a blood vessel. If that clot moves inside the vessel it is referred to as an embolus (embolism). The presence of atherosclerotic plaque lining blood vessel walls is a significant stimulus for clot formation. (27 Sep 1997) |
| blood component removal | Any procedure in which blood is withdrawn from a donor, a portion is separated and retained and the remainder is returned to the donor. (12 Dec 1998) |
| blood component transfusion | 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. (12 Dec 1998) |
| blood corpuscle | <haematology> There are three main types of cell in the blood stream. The red cell, which carries oxygen, the white cell, which fights infections and the platelet, which helps prevent bleeding. The correct balance between each cell type must be maintained for the body to remain healthy. (13 Nov 1997) |
| blood count | <haematology, investigation> The determination of the proper number of red blood cells, white blood cells and platelets are present in the patients blood. Acronym: FBC (16 Dec 1997) |
| blood crisis | The appearance of a large number of nucleated red blood cells in the peripheral blood, accompanied by reticulocytosis and occurring in "exhausted" bone marrow in pernicious anaemia and in haemolytic icterus, a suddenly appearing leukocytosis, indicating a change for the better in the course of a grave blood disease. (05 Mar 2000) |
| blood crystals | <haematology> A substance which appears to be identical to the red-orange bile pigment bilirubin, but which is produced from haemoglobin in tissues rather than within the liver and usually when oxygen tension is low. (09 Oct 1997) |
| blood culture | <investigation, microbiology> A test which involves the incubation of a blood specimen overnight to determine if bacteria are present. (27 Sep 1997) |
| blood cyst | A cyst containing blood or resulting from the encapsulation of a haematoma. Synonym: blood cyst, haematocele, haematocyst, sanguineous cyst. (05 Mar 2000) |
