What is Fibrinogen (Fibrinogen)?

Fibrinogen is measured as part of a coagulation panel. Your fibrinogen is normal.

What does a high Fibrinogen mean?

Your fibrinogen is elevated. As an inflammatory protein, it often rises with infection, inflammation, or pregnancy.

What does a low Fibrinogen mean?

Your fibrinogen is low, which can impair clotting and raise bleeding risk. It can occur with severe liver disease or consumption of clotting factors.

A single value rarely tells the full story — Fibrinogen is best read alongside the rest of your panel. Paste your values or upload your report and get a plain-English explanation of every marker, with the important results flagged.
