Blood culture bottle: Sodium polyanethol sulfonate (anticoagulant) and growth media for microorganisms: Usually drawn first for minimal risk of contamination. [1] Two bottles are typically collected in one blood draw; one for aerobic organisms and one for anaerobic organisms. [2] Blue ("light blue") Sodium citrate (weak calcium chelator ...
The automated red blood cell collection procedure for donating erythrocytes is referred to as 'Double Reds' or 'Double Red Cell Apheresis.' [9] Plateletpheresis (thrombapheresis, thrombocytapheresis) – blood platelets. Plateletpheresis is the collection of platelets by apheresis while returning the RBCs, WBCs, and component plasma.
Examples are thoracocentesis to sample pleural fluid, and amniocentesis to sample amniotic fluid. The main method of centesis, in turn, is fine needle aspiration, but there are also somewhat differently designed needles, such as for bone marrow aspiration. Puncture without aspiration may suffice in, for example, capillary blood sampling.
Erythrocytapheresis can also be used for blood donations. The procedure is commonly done using automated red blood cell collection which involves the removal of two units of red blood cells. This includes either two standard units of red blood cells or one unit plus of red blood cells and another of either plasma or platelets.
Acute posthemorrhagic anemia (also known as acute blood loss anemia) is a condition in which a person quickly loses a large volume of circulating hemoglobin. Acute blood loss is usually associated with an incident of trauma or a severe injury resulting in a large loss of blood. It can also occur during or after a surgical procedure. [19]
A laboratory specimen is sometimes a biological specimen of a medical patient's tissue, fluids, or other samples used for laboratory analysis to assist in differential diagnosis or staging of a disease process. These specimens are often the most reliable method of diagnosis, depending on the ailment.
Blood compatibility testing is routinely performed before a blood transfusion.The full compatibility testing process involves ABO and RhD (Rh factor) typing; screening for antibodies against other blood group systems; and crossmatching, which involves testing the recipient's blood plasma against the donor's red blood cells as a final check for incompatibility.
Patient Blood Management is an approach that can be implemented in hospital settings for taking care of people who require blood transfusions. [4] PBM includes techniques that may help ensure each person receiving a blood transfusion receives optimal treatment for their condition and also ensures that the blood supply (bank of donated blood) is maintained to ensure that all people who require ...
