b. Partial thromboplastin time (PTT)
c. Thrombin time (TT)
d. Kinetic fibrinogen

The PTT is the most commonly used test for monitoring heparin therapy because it responds in a linear fashion over the therapeutic range. The PT is relatively insensitive to heparin, whereas the TT is too sensitive. The kinetic fibrinogen is the least sensitive of these tests to therapeutic heparin.
