What this laboratory test evaluates
Fibrinogen Antigen, Nephelometry
This test measures the levels of fibrinogen in your blood, which can indicate various health conditions. Low fibrinogen levels often point to bleeding issues, commonly due to liver disease or Disseminated Intravascular Coagulation (DIC), a serious condition affecting the blood's clotting process. High fibrinogen levels can signal inflammation in the body and may also suggest an increased risk of atherosclerosis, a disease where plaque builds up inside your arteries.
What patients is this test right for?This test may be recommended if there are concerns about bleeding disorders, liver health, inflammation, or cardiovascular disease risk.
What type of sample is required for this test?1 mL plasma collected in a 3.2% sodium citrate (light blue-top) tube.
Proper collection is crucial for accurate results.
