Fibrinogen Antigen
Also known as: FIBAG
Use
The Fibrinogen Antigen test serves as a follow-up diagnostic tool when fibrinogen activity is decreased. It helps determine whether the decrease is due to insufficient fibrinogen levels or due to dysfunctional fibrinogen. This can be crucial in the diagnosis and management of coagulation disorders where fibrinogen function is implicated.
Special Instructions
This test is approved for use in New York State. It requires careful handling and transportation, specifically necessitating that specimens are kept frozen and separate specimens are submitted when multiple tests are ordered.
Limitations
The test cannot utilize serum samples, EDTA plasma, clotted, grossly lipemic, or hemolyzed specimens. The correct handling and preparation of specimens are critical, as improper handling could result in test failures or inaccurate results. It is also important that the test is performed within the stability period to ensure reliable outcomes.
