If you need to know which are the fibrinogen reference ranges or you require more information about the role of fibrinogen in the blood, you can visit normal fibrinogen level in the blood
A low fibrinogen level in the blood (hypofibrinogenemia) expresses the difficulty to stop bleeding.
If the low level is chronic may be consequence to a deficiency in the production of fibrinogen.
If the decrease in the fibrinogen level appears in an acute way, it may mean an excessive consumption and suggests a problem such as DIC (disseminated intravascular coagulation) or fibrinolysis.
Hypofibrinogenemia or a low blood fibrinogen level means:
A mild hypofibrinogenemia is not usually a matter for concern.
Many drugs can interference fibrinogen level in the blood. Talk to your doctor and make a new test in a few months to see if values return to normal range.
Moderate hypofibrinogenemia requires a visit to your doctor to find out a possible disease.
Bleeding may take longer to stop and additional coagulation test may be performed to look for the underlying cause of this decrease.
A marked hypofibrinogenemia require medical help and in some cases hospitalization.
It may suggest a disease called DIC (Disseminated Intravascular Coagulation) if fibrinogen values are progressively decreasing and so are platelets in the blood.
Your doctor may prescribe you fibrinogen to raise your level to around 200 mg/dl through either fibrinogen concentrate, plasma or cryoprecipitate.
A severe hypofibrinogenemia requires urgent medical help because it is necessary to increase the fibrinogen level in the blood as soon as possible.
Sometimes it may be due to a congenital disorder such as hypofibrinogenemia with fibrinogen values between 20 and 80 mg / dl or congenital afibrinogenemia with total absence of fibrinogen (< 2 mg / dl).
There are some circumstances than can reduce your fibrinogen level in the blood:
Lower than normal level of fibrinogen in the blood can be due to the following diseases:
If your fibrinogen level is low, it is important not to take anticoagulant medication to avoid prolonged bleeding.
It is also advisable not to practice contact sports such as boxing, soccer or hockey to avoid injuries and bleeding.
In case you need a supplementary supply of fibrinogen there are several possibilities using fibrinogen concentrate, plasma or cryoprecipitate.

The following values are considered to be above the normal range:
IMPORTANT: These levels are expressed in mg/dL. They are an example of a healthy man/woman of about 45 years old, with a balanced diet, not known disease and not taking any medication. The ranges can be different depending on the laboratory or on your personal circumstances.
