Monitoring heparin treatment with the APTT: the effect of methodological changes on the APTT

The Netherlands Journal of Medicine, 1996
To assess the effect on the desired activated partial thromboplastin time (APTT) of altered practice in the laboratory control of heparin treatment.Descriptive study of the number of APTTs in the desired range (DR) in 1987 (historical controls) and in 1992/1993.

Spontanhämatome bei isoliert erhöhter aPTT

Praxis, 2011
Wir berichten über eine 64-jährige Patientin mit Spontanhämatomen. Eine Blutungsneigung war bisher nicht bekannt. Die Gerinnungsabklärung ergab eine isoliert verlängerte aPTT. Als Ursache konnte ein Inhibitor gegen Faktor VIII ohne fassbare Ursache (idiopathische Hemmkörperhämophilie) gefunden werden.

PT AND aPTT TRENDS IN DENGUE FEVER

INTERNATIONAL JOURNAL OF SCIENTIFIC RESEARCH, 2022
Dengue is the the most common mosquito borne arboviral disease in tropical regions of the world. Common hematological abnormalities seen with dengue fever are leukopenia followed by thrombocytopenia. Coagulopathy may also be seen in dengue fever. This study aims to observe the trends of PT and aPTT prole in dengue fever.

Variability in Heparin Sensitivity of APTT Reagents

American Journal of Clinical Pathology, 1986
Activated partial thromboplastin time (APTT) is the most widely used coagulation test for monitoring heparin therapy. This study quantitates the differences in heparin sensitivity of seven commercially available APTT reagents, using plasma samples obtained from 20 subjects. The reagents studied were Actin, Actin FS, Automated APTT, Cephotest, Coagachek

Comparison of Two APTT Methods of Monitoring Heparin Therapy: APTT Ratio and Heparin Response of Pooled Normal Plasma

American Journal of Clinical Pathology, 1990
The sensitivity of the reagents for activated partial thromboplastin time (APTT) test varies greatly. Consequently the physicians who prescribe heparin based on certain APTT ratios may order different doses of heparin and produce different levels of anticoagulation in their patients, depending on the sensitivity of APTT reagent used by the laboratory ...

STANDARDIZATION OF THE APTT TEST CURRENT STATUS

Scandinavian Journal of Haematology, 1980
The partial thromboplastin time (PTT) which is used as an overall measure of the intrinsic clotting system, is the commonest coagulation test employed in routine laboratories apart from the prothrombin time. The main functions of the test are: 1. to screen intrinsic coagulation defects; 2. to control heparin administration; 3.

Performance characteristics of a new synthetic APTT reagent

Clinical & Laboratory Haematology, 1998
Performance characteristics of a totally synthetic activated partial thromboplastin time (APTT) reagent, recently available commercially, were evaluated and compared with a rabbit-brain extracted reagent. We found that the synthetic reagent, Synthasil, returned significantly higher normal APTT values than the brain-extracted reagent, Thrombosil.

latrogenic Prolonged aPTT: A Nondisease State

JAMA: The Journal of the American Medical Association, 1974
The use of various types of indwelling catheters and needles for monitoring physiological parameters and for administration of intravenous fluids and medication is now widespread. Such catheters also provide a ready means of obtaining blood samples. Far too little attention, however, has been paid to errors that may arise in tests performed on blood ...
