Erroneous Activated Partial Thromboplastin Time

Annals of Internal Medicine, 1978
Excerpt To the editor: We wish to draw attention to the problem of erroneous results of activated partial thromboplastin times (aPTT) when plasma samples from patients on heparin are tested with th...

Biological variation estimates of prothrombin time, activated partial thromboplastin time, and fibrinogen in 28 healthy individuals

International Journal of Laboratory Hematology, 2018
Although tests of global hemostasis prothrombin time (PT) and activated partial thromboplastin time (aPTT) should not be used for prediction of bleeding risk, these tests are often used by many clinicians in daily practice particularly as a preoperative ...

Effect of Warfarin on the Activated Partial Thromboplastin Time

Drug Intelligence & Clinical Pharmacy, 1986
Outpatients followed in an anticoagulation clinic were studied retrospectively to determine the effect of warfarin on the activated partial thromboplastin time (APTT). Twenty-nine patients were studied in part 1 of the trial to determine whether their APTT values were elevated when their prothrombin time (PT) was within 1.5 to 2.5 times the control PT.

Retrospective evaluation of shortened prothrombin time or activated partial thromboplastin time for the diagnosis of hypercoagulability in dogs: 25 cases (2006-2011).

Journal of Veterinary Emergency and Critical Care, 2016
OBJECTIVE To evaluate the relationship between shortened prothrombin time (PT) or activated partial thromboplastin time (aPTT) values, clinical findings associated with hypercoagulability, suspicion of pulmonary thromboembolism (PTE), D-dimer ...

Prothrombin and Partial Thromboplastin Time

2016
Basic plasma coagulation function is readily assessed with a few simple in vitro laboratory tests, prothrombin time (PT) and partial thromboplastin time (PTT), and they are useful as the current standard for establishing a diagnosis of coagulopathy.

Spurious Prolongation of the Activated Partial Thromboplastin Time

Thrombosis and Haemostasis, 1977
SummaryThe clinical and laboratory data of 8 patients (4 males and 4 females) with circulating anticoagulant were presented. Based on prolonged APTT, failure to correct the APTT with 50 % normal plasma and abnormal tissue thromboplastin inhibition test, the inhibitor was identified as “middle stage” – or the “lupus anticoagulant”.

False Elevation of Partial Thromboplastin Time and Prothrombin Time

JAMA: The Journal of the American Medical Association, 1970
A partial thromboplastin time (PTT) and a prothrombin time (PT) performed as routine preoperative screening on a young woman hospitalized for preeclampsia were unexpectedly and markedly prolonged. Since there was no clinical suspicion of a bleeding disorder, and since results of numerous repeat tests were normal, an artifact was suspected.

Use of the Activated Partial Thromboplastin Time

Annals of Internal Medicine, 1988
Excerpt To the Editor:In connection with a recent article (1), I pose a question. Should peridural anesthesia in women with otherwise normal bleeding history be preceded by coagulation tests to pre...

The activated partial thromboplastin time (APTT) [PDF]

open access: possible, 1992
The term partial thromboplastin is used to distinguish the reagent from that used in the prothrombin time, since the APTT reagent lacks the apoprotein component of the complete tissue thromboplastin. The APTT is the main test for screening for intrinsic clotting defects including haemophilia. It is also used for detection of lupus anticoagulant and for

Routine Use of the Prothrombin and Partial Thromboplastin Times

JAMA: The Journal of the American Medical Association, 1989
The prothrombin time (PT) and activated partial thromboplastin time (APTT) tests are often routinely ordered for hospitalized patients. Ordering patterns and clinical indications for the PT and APTT tests on the medical service at a teaching hospital were studied. Eighty-one percent of all patients admitted to the medical service had a PT and APTT test
