The Fibrinogen Test measures the concentration of fibrinogen, a vital protein in the blood that plays a crucial role in the coagulation process. Abnormally low levels of fibrinogen can impair the blood's ability to clot effectively, leading to increased bleeding risk. Conversely, elevated fibrinogen levels are associated with a higher risk of thrombotic events, such as heart attack and stroke.

A physician may order a fibrinogen test to investigate various symptoms and conditions, including:

* Symptoms of bleeding:
* Gum bleeding
* Gastrointestinal bleeding
* Hematuria (blood in urine) or Melena (blood in stool)
* Hemoptysis (coughing up blood)
* Excessive or prolonged bleeding
* Frequent nosebleeds
* Suspected organ rupture, such as splenic rupture

* Other clinical indications:
* Investigation of abnormal coagulation panel results (e.g., prolonged APTT)
* Signs or symptoms suggestive of a blood clotting disorder
* Suspected disseminated intravascular coagulation (DIC)
* Evaluation for genetic disorders affecting blood coagulation
* History of recurrent miscarriages
