OBJECTIVES To assess the impact of sugammadex on activated partial thromboplastin time (APTT) and international normalized ratio for prothrombin time (PT(INR)) in healthy subjects and characterize the concentration-dependency of sugammadex effects on ...

Consumption Time Is Not Prothrombin Time
JAMA, 1964To the Editor:— Regarding the communication, "Spontaneous Intracranial Hematomas in Patients Receiving Anticoagulation Therapy" (JAMA187:396 [Feb 8] 1964), Drs. Dooley and Perlmutter comment that "The degree of anticoagulation in patients receiving coumarin derivatives is usually evaluated by measuring the prothrombin consumption time." It is ...

A fully integrated prothrombin time test on the microfluidic disk analyzer.
Journal of Nanoscience and Nanotechnology, 2013A fully integrated prothrombin time test, which is capable of measuring the time required for blood to coagulate, is presented in this study. The microfluidic functions integrated on the microfluidic disk were able to extract the plasma from whole blood ...

The Influence of Heparin on the Prothrombin Time
Pharmacotherapy: The Journal of Human Pharmacology and Drug Therapy, 1991We studied the effect of known concentrations of heparin on the prothrombin time (PT) in patients receiving warfarin and in controls who were not anticoagulated. Plasma from the subjects and controls was serially diluted with known concentrations of heparin, and PT was measured.

Thromboplastin Time (Prothrombin Time)
1965Publisher Summary This chapter elaborates thromboplastin time that is, prothrombin time. Blood plasma contains 300–400 mg% fibrinogen, and during coagulation of blood this is converted to insoluble fibrin by thrombin. The highly active enzyme thrombin is formed from an inactive precursor, prothrombin.

JAMA: The Journal of the American Medical Association, 1965
To the Editor:— Oral anticoagulation remains a complicated subject involving many facets, but one variable could be made a constant if the one-stage prothrombin time were carried out by the standard technique outlined over 25 years ago, when I explicitly described the preparation of thromboplastin.

Simplified Prothrombin Time Standardization
Pathophysiology of Haemostasis and Thrombosis, 1994An analysis of prothrombin time (PT) standardization methods is presented. The present recommended ratio method demonstrated complex calibration and wide therapeutic ranges. Standardization by coagulation activities resulted in different therapeutic ranges due to the different sensitivity of assays for the protein induced by vitamin K absence (Pivka ...

The prothrombin time test [PDF]
, 1992 The prothrombin time (PT) is the screening test for the extrinsic (tissue) clotting system. The PT was originally introduced by Quick1 as a measure of a coagulation defect in the newborn and jaundiced patients, and subsequently adapted for its present principal uses in the screening of extrinsic clotting and in monitoring of oral anticoagulant dosage ...

The action of Dicumarol in the human being on plasma prothrombin time and total prothrombin time
American Heart Journal, 1952Abstract In man, Dicumarol causes an increase in the plasma and in the total prothrombin times. The explanation is offered that Dicumarol reduces both the free and total prothrombin and that a rough ratio between the two forms is maintained. The practical significance of this observation is discussed.
