Fresh normal plasma has all the blood coagulation factors with normal levels. If the problem is a simple factor deficiency, mixing the patient plasma 1:1 with plasma that contains 100% of the normal factor level results in a level ≥50% in the mixture (say the patient has an activity of 0%; the average of 100% + 0% = 50%).

Sigmund Rascher (12 February 1909 – 26 April 1945) was a German Schutzstaffel (SS) doctor. He conducted deadly experiments on humans pertaining to high altitude, freezing and blood coagulation under the patronage of Reichsführer-SS Heinrich Himmler, to whom his wife Karoline "Nini" Diehl had direct connections.
Blood clotting tests are the tests used for diagnostics of the hemostasis system. Coagulometer is the medical laboratory analyzer used for testing of the hemostasis system. Modern coagulometers realize different methods of activation and observation of development of blood clots in blood or in blood plasm
A study found that for those with health issues, including diabetes, eating 6-12 eggs per week didn’t have a negative effect on the total blood cholesterol levels or heart disease risk factors ...
Clotting time is a general term for the time required for a sample of blood to form a clot, or, in medical terms, coagulate.The term "clotting time" is often used when referring to tests such as the prothrombin time (PT), activated partial thromboplastin time (aPTT or PTT), activated clotting time (ACT), thrombin time (TT), or Reptilase time.
Xenopus egg extract is a lysate that is prepared by crushing the eggs of the African clawed frog Xenopus laevis. It offers a powerful cell-free (or in vitro ) system for studying various cell biological processes, including cell cycle progression, nuclear transport , DNA replication and chromosome segregation .
Quality control is an important requirement in laboratory and POC testing. An automatic internal electronic control procedure is implemented in the ROTEM whole blood analyzer. Furthermore, biological control materials at 2 different levels are available and should be used in order to document quality and validity of results.
Coagulation, the changing of blood from a liquid to a gel which forms the fibrin clots, is essential to hemostasis. Intact blood vessels moderate blood's tendency to form clots . The endothelial cells of intact vessels prevent blood clotting with a heparin-like molecule and thrombomodulin , and prevent platelet aggregation with nitric oxide and ...
