Prothrombin Time Standardization
Acta Clinica Belgica, 1987SummaryAs recommcndcd by the proper authorities, the prothrombin time results for patients under oral anticoagulant therapy arc reported by our laboratory in International Normalized Ratios (I.N.R.).For the calculation of the INR-values we use a calibration factor, the International Sensitivity Index (I.S.I.), provided by the manufacturer of the ...

ESTIMATION OF PROTHROMBIN TIME
Journal of the American Medical Association, 1948To the Editor:— The opinion grows that the results of estimation of prothrombin time should be reported in terms of per cent or of per cent of normal. Recently, a plea has been made that the practice be made universal (Allen, E. V.:The Journal, page 323, May 24, 1947).

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 ...

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.

One-stage Prothrombin Time Survey
American Journal of Clinical Pathology, 1970Results of a one-stage prothrombin time proficiency testing program are reported. Fifty-three participating laboratories using various technics and reagents performed onestage prothrombin time tests on four plasma specimens. These results were compared with determinations performed by eight reference laboratories. Basing acceptability of performance on

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.
