Plasma Fibrinogen Test in Delhi NCR

Know More About This Test

Fibrinogen is a plasma protein produced by the liver.

Plays a central role in blood clot formation.

Converted to fibrin during coagulation.

Acts as an acute-phase reactant.

Important marker in bleeding and thrombotic disorders.

Why Is This Test Recommended?

• Evaluation of bleeding disorders
• Suspected clotting abnormalities
• Monitoring disseminated intravascular coagulation (DIC)
• Cardiovascular risk assessment
• Liver disease evaluation

Understanding Fibrinogen Levels

• Normal range: ~200400 mg/dL
• Low levels increase bleeding risk
• High levels indicate inflammation or thrombosis risk
• Elevated in infections and pregnancy
• Reduced in severe liver disease

Symptoms or Conditions Requiring Testing

• Unexplained bleeding
• Excessive clot formation
• Post-surgical bleeding
• Chronic inflammatory conditions
• Liver dysfunction

Preparation and Procedure

• Fasting not mandatory
• Blood drawn into special citrate tube
• Avoid recent anticoagulant changes
• Simple venipuncture
• Minimal discomfort

Interpretation & Follow-Up

• Low fibrinogen → bleeding tendency
• High fibrinogen → cardiovascular risk
• Correlate with PT, APTT
• Repeat testing monitors therapy
• Guides transfusion decisions

FAQs

• Is fibrinogen part of clotting profile? Yes, fibrinogen is a key component of a standard clotting profile, as it directly influences the final stages of coagulation and is often measured alongside tests like PT and aPTT to assess overall hemostatic function.
• Can infection raise levels? Yes, infections can significantly raise fibrinogen levels because it acts as an acute-phase reactant, increasing during inflammation to support clot formation and immune response, which is why elevated results are common in bacterial or viral illnesses.
• Is fasting required? No, fasting is not required for fibrinogen testing, as levels are primarily influenced by liver production and inflammation rather than recent food intake, allowing for flexible scheduling.
• Is it liver-related? Yes, fibrinogen is closely liver-related, since it is synthesized exclusively by the liver, and low levels often signal impaired liver function, such as in cirrhosis or acute hepatitis.
• Can levels normalize? Yes, fibrinogen levels can normalize with appropriate treatment of the underlying cause, such as resolving an infection, managing liver disease, or adjusting medications, typically within days to weeks depending on the severity.
