Coagulation Studies

Interpret Prothrombin Time (PT/INR) and Partial Thromboplastin Time (PTT) to localize defects in the coagulation cascade.

Correlate the effects of vitamin K deficiency and liver disease with PT/INR and PTT results.

Differentiate the laboratory findings associated with warfarin versus unfractionated heparin therapy.

Interpret D-dimer results in the appropriate clinical context for thrombosis evaluation.

Recognize the classic coagulation pattern of disseminated intravascular coagulation (DIC).

Assess bleeding risk from coagulation study results prior to invasive procedures.
