Fibrinogen

Fibrinogen, also known as Factor I, is a protein made by the liver and released into the blood. It plays a key role in blood clotting. It is converted into fibrin, which forms the mesh that helps stop bleeding after an injury. Adequate fibrinogen levels are necessary for normal clot formation, while abnormal levels can cause excessive bleeding or unwanted clotting (thrombosis).

The Fibrinogen test may be recommended if there are symptoms of a bleeding or clotting disorder, such as excessive or prolonged bleeding from cuts or injuries, unexplained bruising or nosebleeds, blood clots in the legs (deep vein thrombosis) or lungs (pulmonary embolism). The test is also used to monitor conditions that affect fibrinogen levels, including liver disease, disseminated intravascular coagulation (DIC), or certain cancers. In some cases, it may be done before surgery to evaluate clotting ability. Routine fibrinogen testing is particularly important during pregnancy for individuals with a history of abnormal bleeding or past pregnancy complications linked to fibrinogen disorders.

Overnight fasting is preferred for this test, but it is not mandatory. A completed coagulation requisition form (Annexure - CR/05) must be provided at the time of sample collection. It is also important to share complete clinical details along with medication history or a doctor’s prescription, as this information helps in accurately interpreting the test results.

Test result ranges are approximate and may differ slightly between labs depending on the methodology and laboratory guidelines. Do not self-medicate and always consult a doctor to understand the test results correctly.
