What is Fibrinogen?
Fibrinogen test helps in diagnosing bleeding disorders or problems associated with blood clotting. Fibrinogen is also known as the coagulation factor I. The fibrinogen activity test helps in measuring the amount of fibrinogen.
The fibrinogen activity test measures the time taken for soluble fibrinogen to get converted to fibrin after the addition of a small amount of thrombin. This is directly proportional to the amount of fibrinogen present in the blood.
During the procedure, a blood sample is taken from a vein in your arm. A result of fibrinogen in the range of 200 - 400 mg/dL is considered normal. If it is less than 50 mg/dL, it indicates fewer clotting factors. If more than 700 mg/dL high risk of blood clotting in the heart and brain.
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.
Interpreting Fibrinogen results
The normal range for fibrinogen in blood is 200 to 400 mg/dL of blood.
