Fibrinogen Test – Normal Range

The normal values for fibrinogen test are 150 – 400 mg/dl, and this range is unisex for all age groups.

Chronically low levels may be related to decreased production due to an inherited condition such as afibrinogenemia or hypofibrinogenemia or to an acquired condition such as end-stage liver disease or severe malnutrition.

Acutely low levels are often related to consumption of fibrinogen such as may be seen with disseminated intravascular coagulation (DIC) and abnormal fibrinolysis, which occurs when the body is overactive in clearing blood clots.

Reduced fibrinogen levels may also occur following rapid, large-volume blood transfusions and in people who are malnourished.
