For an isolated prolonged aPTT, the best initial test is a mixing study. It separates a factor deficiency (corrects: then measure factors VIII/IX and vWF/ristocetin activity) from an inhibitor (does not correct, e.g. lupus anticoagulant).
- Factor VII and fibrinogen are not the first step: factor VII affects the PT, and fibrinogen would affect both PT and aPTT.
