Fibrinogen – what do your levels mean?
Have you had your Fibrinogen level measured and are unsure what the numbers mean? Here's a clear explanation of the normal range, what a high or low level can indicate, and when it makes sense to get tested.
What is the normal range for Fibrinogen?
What is the normal range for Fibrinogen?
The normal range for fibrinogen in plasma is typically between 5.2 and 12.6 µmol/L. This interval can vary depending on the laboratory's specific methods and reference values. Additionally, factors such as age, gender, and physiological conditions like pregnancy can affect the levels. For example, higher values are often seen during pregnancy and in inflammatory conditions, as fibrinogen is an acute-phase reactant. Being close to the boundary values can indicate an underlying condition, such as liver disease or coagulation disorders, and should be evaluated in a clinical context.
What does a low level mean?
A low level of fibrinogen can lead to an increased risk of bleeding, as fibrinogen is crucial for blood clot formation. Symptoms may include easy bruising, nosebleeds, or prolonged bleeding after minor injuries. Common causes of low levels include severe liver disease, disseminated intravascular coagulation (DIC), and genetic disorders such as hypofibrinogenemia. Individuals with chronic diseases or those receiving thrombolytic treatment are particularly at risk. It is recommended to consult a doctor for further investigations and possible treatment if low levels are detected.
What does a high level mean?
A high level of fibrinogen can be a sign of an underlying inflammatory or infectious condition, as fibrinogen increases as part of the body's acute response. Symptoms are often not directly related to fibrinogen, but to the underlying cause, such as fever or swelling. Common causes include chronic inflammatory diseases, pregnancy, and certain types of cancer. Very high levels may increase the risk of blood clots, which requires medical follow-up. It is important to contact a doctor if high levels are detected, to identify and treat the underlying cause.
