UPLOAD YOUR BLOOD TEST

Fibrinogen is a protein produced by the liver that plays a crucial role in blood clotting. This test measures the amount of fibrinogen in the blood. It's essential for assessing the body's ability to form blood clots and stop bleeding. Fibrinogen levels may be checked if a person has unexplained bleeding or clotting disorders, or to monitor certain liver diseases. Abnormal levels can indicate various conditions, including liver disease, malnutrition, or disseminated intravascular coagulation (DIC). It's also used to evaluate the risk of cardiovascular diseases, as high fibrinogen levels are associated with increased risk of heart attack and stroke.

What do readings below 200 mg/dL for Fibrinogen - FIB mean?

A low fibrinogen level (below 200 mg/dL) can indicate several conditions:

  1. Severe liver disease, as the liver produces fibrinogen
  2. Disseminated intravascular coagulation (DIC), a serious blood clotting disorder
  3. Hereditary fibrinogen deficiency, a rare genetic disorder
  4. Malnutrition or severe malabsorption
  5. Excessive blood loss or hemodilution

Low fibrinogen levels can lead to difficulty in forming blood clots, potentially resulting in excessive bleeding or prolonged healing times for wounds.

What do readings above 400 mg/dL for Fibrinogen - FIB mean?

A high fibrinogen level (above 400 mg/dL) can be indicative of several conditions:

  1. Inflammation or infection in the body
  2. Certain cancers, particularly lung, breast, or colon cancer
  3. Pregnancy or use of oral contraceptives
  4. Obesity
  5. Smoking
  6. Cardiovascular diseases or increased risk of heart attack and stroke
  7. Acute phase reactions to stress, surgery, or trauma

Elevated fibrinogen levels may increase the risk of blood clots forming in blood vessels, potentially leading to thrombosis, heart attack, or stroke.
