Description
Why It’s Done:
This test is performed to:
• Assess bleeding or clotting disorders: Low fibrinogen levels can indicate bleeding disorders (e.g., disseminated intravascular coagulation (DIC)), while high levels may suggest increased risk of thrombosis (clot formation).
• Evaluate liver function: Since fibrinogen is produced in the liver, abnormally low levels can indicate liver disease or failure.
• Monitor inflammatory conditions: Fibrinogen levels can rise in response to inflammation, making this test useful for monitoring conditions like rheumatoid arthritis, lupus, and infections.
• Monitor treatment: It helps monitor the effectiveness of treatments for clotting or bleeding disorders, as well as other therapies like anticoagulants.
Preparation:
• Fasting: Typically, fasting is not required for this test, though it may be requested in some cases if other tests are being performed simultaneously.
• Medications: Inform your healthcare provider about any medications you’re taking, especially blood thinners (e.g., warfarin, aspirin) or clotting factor medications, as these can affect fibrinogen levels.
• Blood Sample: A blood sample will be drawn from a vein in your arm. The procedure is quick and typically painless.
• Timing: No specific timing is required for the test unless otherwise directed by your doctor, but it’s often performed in conjunction with other tests related to clotting or liver function.
