Overview of Fibrinogen
What is Fibrinogen?
Also known as Factor I and Functional or Serum Fibrinogen Test, it is primarily used to detect the presence of fibrinogen in the blood. Fibrinogen is a blood plasma protein that helps in clotting of blood when there is tissue damage. If you are fibrinogen deficient, which is normally a genetic defect, your blood cannot coagulate resulting in excessive loss of blood.
Why is Fibrinogen done?
The test is required to detect a bleeding disorder thereby evaluating the concentration of fibrinogen in the blood and also helps analyse cardiovascular disease. Bleeding disorder symptoms such as easy bruising, or bleeding from any site of the body, low blood pressure and low blood counts also result due to abnormal fibrinogen content.
Preparation for Fibrinogen
- Do not eat or drink anything other than water for 8-12 hours before the test.
Sample Type for Fibrinogen
Interpreting Fibrinogen results
The normal range for fibrinogen in blood is 200 to 400 mg/dL of blood.
