Activated partial thromboplastin time (APTT)

a. Is the same as prothrombin time (PT)
b. Is more sensitive than PT in determining clotting
c. Is the same as partial thromboplastin time (PTT)
d. Is lower than the therapeutic range in which a patient may have bleeding problems


B
APTT (response B) evaluates all clotting factors by measuring the time needed to form a clot. It is more sensitive than PTT. APTT is used for monitoring anticoagulation by heparin. If laboratory values are below the therapeutic range (response D), clotting occurs too quickly, meaning that anticoagulation therapy has been unsuccessful.
