Influence of oral contraceptives on coagulation tests in native blood and plasma [PDF]
International Journal of Gynecology & Obstetrics, 1990 Routine coagulation laboratory tests, clotting times in native (not anticoagulated) whole blood, platelet-rich and platelet-poor plasma, and recalcification times in citrated whole blood, platelet-rich and platelet-poor plasma were performed in 14 healthy premenopausal women.

Mathematical Model for the Blood Coagulation Prothrombin Time Test
Thrombosis Research, 1998A mathematical model for the prothrombin time test is proposed. The time course of clotting factor activation during coagulation was calculated, and the sensitivity of the test to a decrease in the concentrations of coagulation proteins or their activities was studied. The model predicts that only severe coagulation disorders connected with a more than

Value of Blood Coagulation Tests in Ischemic Cerebral Disease
European Neurology, 198680 patients with transitory ischemic attacks (TIA) and 30 patients with cerebral infarction (CI) were investigated regarding hemostatic disturbances to evaluate selected coagulation test methods for routine laboratory use. The patients were studied a few days after the first appearance of symptoms and at defined times subsequently.

Activation of Blood Coagulation during Inhalation Challenge Tests
Allergy, 1981Bronchial challenge tests were performed in 16 asthmatic subjects. Eight developed an immediate and eight a dual asthmatic response. In all patients serial blood samples were analysed for plasma recalcification time and Factor XII activation rate. In all instances a profound shortening of the recalcification time was found, but only in patients with a ...

Point-of-Care Tests in for Blood Coagulation in the Perioperative Period
2021In 1948, Hellmut Hartert demonstrated hemostatic function for whole blood samples using thromboelastography. He introduced the concept of visco-elasticity and developed a whole blood test which is now routinely used in clinical situations involving blood loss, coagulation status, and needed component treatment.

Coagulation Testing of Hickman Catheter Blood in Patients With Acute Leukemia
Archives of Internal Medicine, 1986We quantified coagulation parameters in vitro using standard automated methods in 12 adult patients with acute leukemia who also had Hickman catheters (HC). Test results from simultaneously obtained HC blood and control peripheral venous blood (PB) samples were compared in the respective patients.

Tests of Blood Coagulation and Hemostasis
JAMA, 1967Previous articles in this series have dealt with the prothrombin time (PT) and the coagulation time (CT).1,2For many years these were the only tests available for the detection of clotting disorders. With the development of the thromboplastin generation test (TGT) and the partial thromboplastin time (PTT3,4), clinically important clotting defects which

Blood coagulation dynamic testing sensor based on electromagnetic vibration
Proceedings of the Institution of Mechanical Engineers, Part H: Journal of Engineering in Medicine, 2019Rapid detection techniques and methods of blood coagulation have attracted wide attention in academia and the business community in the presence of the increased demands for rapid assessment (point-of-care testing) of patients from surgery, intensive care unit, and other departments.
