coagulation factor assay

coagulation factor assay

Any test that measures levels or functional activity of one or more coagulation factors; the one-stage extrinsic CFA is abnormal in the face of defects of one or more of the following factors: II, V, VII, or X; the one-stage intrinsic CFA evaluates factors VIII, IX, XI, XII. See Extrinsic pathway, Factor(s. ), Intrinsic pathway. Cf Coagulation panel.

Also of note is that although coagulation factor assays are designed to quantify factor activity levels, the assays can also detect interfering inhibitors, including LAC and inhibitors of individual factors (in which "nonparallelism" indicates the presence of an inhibitor), and therefore are an integral part of laboratory investigations of isolated aPTT prolongation, as was demonstrated in this case.
However, the effect of isocitrate on specific coagulation factor assays has not yet been studied.
