Detection and quantitation of inhibitor to coagulation factor VII


This test is not useful for the detection of a lupus-like circulating anticoagulant inhibitor or other inhibitors that are not specific for coagulation factors.


This test is not useful for the detection of a nonspecific circulating anticoagulant.

Profile Information A profile is a group of laboratory tests that are ordered and performed together under a single Mayo Test ID. Profile information lists the test performed, inclusive of the test fee, when a profile is ordered and includes reporting names and individual availability.

Testing Algorithm Delineates situations when tests are added to the initial order. This includes reflex and additional tests.

Testing begins with coagulation factor VII activity assay with dilutions to evaluate assay inhibition; if the factor VII activity assay is decreased, an inhibitor screen will be performed to look for specific factor VII inhibition. If specific inhibition is apparent, the titer of the inhibitor will be determined.
