WebAbstract. Activated partial thromboplastin time (PTT) is a routine coagulation screening test that is sensitive to declines of activities of factors II, V, VIII, IX, XI, XII, kallikrein, high-molecular-weight kininogen, and reduced concentration of fibrinogen. It is also utilized to monitor heparin therapy and some other anticoagulant drugs. WebConclusions: aPTT and anti-Xa values are frequently discordant when used to measure UFH in hospitalized patients. A disproportionate prolongation of the aPTT relative to the anti-Xa was the most common discordant pattern in our study. Patients with relatively high aPTT to anti-Xa values appear to be at increased risk of adverse outcomes.
