Extremely Shortened Activated Partial Thromboplastin Times
JAMA: The Journal of the American Medical Association, 1980To the Editor.— The presence of a hypercoagulable state in patients with a shortened activated partial thromboplastin time (APTT) as manifested by the clinical association with an increased incidence of thromboembolic disease has previously been reported by Hume, 1 Gallus et al, 2 Pilgeram, 3 McKenna et al, 4 and McKenna et al.

Kaolin-correctable Prolongation of the Activated Partial Thromboplastin Time
American Journal of Clinical Pathology, 1980Seven patients who had normal prothrombin times but prolonged activated partial thromboplastin times (aPTT) are described. The prolonged aPTT, obtained with micronized silica as the contact activating agent in a semi-automated optical end-point system, a nonautomated optical end-point system, and a conductivity end-point system, corrected to normal ...

How to report results of prothrombin and activated partial thromboplastin times
Clinical Chemistry and Laboratory Medicine (CCLM), 2016AbstractProthrombin time (PT) and activated partial thromboplastin time (APTT) are the most widely used tests to investigate coagulation abnormalities. Varied result reporting have been introduced over the years for the two tests, thus making their interpretation rather confusing in different clinical settings. PT results have been reported as clotting

The Activated Partial Thromboplastin Time in the Control of Heparin Treatment
Australasian Annals of Medicine, 1970SummaryThe effect of heparin on the activated partial thromboplastin time and whole blood clotting time was measured in 30 patients with thrombo‐embolic disease. In 27 of these patients there was good correlation between the results of the two tests. Three patients showed little change of the activated partial thromboplastin time, although the clotting

Heparin Monitoring in Sheep by Activated Partial Thromboplastin Time
Artificial Organs, 2003Abstract: Heparin anticoagulation is utilized during and after vascular surgery in animals to reduce the risk of acute or chronic thromboembolic problems. In this study, we examined variation of activated partial thromboplastin time APTT) after the intravenous bolus IV bolus) and subcutaneous SC) heparin injection in order to monitor heparin therapy in

Comparison of Reagents for Determining the Activated Partial Thromboplastin Time
Thrombosis and Haemostasis, 1978SummarySix commercially available reagents for the determination of the activated partial thromboplastin time have been evaluated and compared with respect to their sensitivity to the coagulation factors VIII, IX and XI and to their response to heparin.

Comparison of Several Activated Partial Thromboplastin Time Methods
American Journal of Clinical Pathology, 1975Activated partial thromboplastin times (APTT's) performed with a semi-automated electrical-conductivity type of clot timer on plasmas from patients with hepatic disease and intravascular coagulation, and on warfarin or heparin therapy, were significantly lower than when done on the same plasmas with either a manual optical method or an automated ...

A Prolonged Activated Partial Thromboplastin Time in a Child With Hodgkin Lymphoma
Journal of Pediatric Hematology/Oncology, 2020A 3-year-old girl presented with fever and left-sided neck mass that did not resolve despite antibiotic treatment. Physical examination was normal except lymphadenopathy in the left cervical region. Complete blood count was Hb: 8.01 g/dL, leukocyte count: 4034/mm3, platelet count: 286,000/mm3.

Thein VitroEffect of Heparin on the Activated Partial Thromboplastin Time
American Journal of Clinical Pathology, 1972The in vitro effect of heparin on the activated partial thromboplastin time was studied using plasma from normal subjects. It was found that there is a log-dose response to heparin which is quite variable from subject to subject. A single subject was studied on five occasions in a 2-month interval; all of this subject’s response patterns to heparin ...

Activated Partial Thromboplastin Time: New Tricks for an Old Dogma
Seminars in Thrombosis and Hemostasis, 2008The activated partial thromboplastin time (APTT) is the most common coagulation test procedure performed in routine laboratories, apart from the prothrombin time. The test is traditionally used for identifying quantitative and qualitative abnormalities in the intrinsic and common pathways of coagulation, monitoring anticoagulant therapy with ...
