Correlation Between Activated Clotting Time and Activated Partial Thromboplastin Times
The Annals of Pharmacotherapy, 2002OBJECTIVE: To evaluate the correlation between clotting time tests and heparin concentration, the correlation between activated clotting time (ACT) and activated partial thromboplastin time (aPTT) results, and to compare the clinical decisions based on ACT results with those based on aPTT results.

Prothrombin Time and Partial Thromboplastin Time Assay Considerations
Clinics in Laboratory Medicine, 2009Prothrombin times and activated partial thromboplastin times have long been used as tests of overall ("global") clotting function. Laboratory coagulation testing issues should be at the forefront of the reader's consciousness whenever critically evaluating and extrapolating published study conclusions reliant on the results of these tests.

Coagulation Studies: Prothrombin Time, Partial Thromboplastin Time, Bleeding Time
Emergency Medicine Clinics of North America, 1986Three coagulation tests available in the emergency department are described in this article. Methods, results, and implications in the bleeding patient are reviewed.

Partial Thromboplastin Time Reagents: Another Look
Laboratory Medicine, 1985Ellagic acid and micronized silica, respectively, are the activating agents in two commonly used commercial partial thromboplastin time reagents. The two reagents were compared for their ability to detect partial deficiencies of clotting factors. The normal ranges for each were first determined using one semiautomated clot-detecting machine.

Prothrombin Time and Activated Partial Thromboplastin Time
2009Publisher Summary This chapter discusses the prothrombin time (PT) and activated partial thromboplastin time (PTT) which are two separate but related in vitro laboratory assays that are used to evaluate coagulation factors. Factors involved uniquely in the PTT are referred to as intrinsic pathway factors, whereas factors unique to the PT are referred

Performance guidelines for the partial thromboplastin time test
La Ricerca in Clinica e in Laboratorio, 1989The partial thromboplastin time (PTT) test is widely used as a screening test for the detection of hemophilia. It is also used to monitor patients on heparin anticoagulation. These proposed guidelines for the performance of this test, including comparable reference ranges, precision and sensitivity requirements are felt to be reasonable and attainable.

Use of Micro Partial Thromboplastin Time Test
JAMA, 1964To the Editor:— Dr. J. B. Miale is to be congratulated on his excellent study ( JAMA 185 :752 [Sept 7] 1963) of the value of the partial thromboplastin time (PTT) as a screening test. His introduction of the strikingly reliable micro technique will be welcomed in pediatric practice. But, I will challenge Dr. Miale on one major point. His main thesis
