Fibrinogen
Here’s what it reflects — and what to do about it.
Longetic pulls together every lab and record you’ve had, follows how Fibrinogen changes over time, and explains what’s shifting — so you walk into your next appointment prepared, with reminders for retests along the way.
What is Fibrinogen?
A protein made by the liver that helps your blood form clots and also rises with inflammation.
Fibrinogen is a clotting protein produced by the liver, and it is essential for stopping bleeding by helping blood clots take shape. Levels can go up with inflammation, infection, or pregnancy, and higher long-term levels have been associated in research with a greater tendency toward clotting and cardiovascular risk, while very low levels can be associated with bleeding problems. It is measured mainly when evaluating clotting or bleeding rather than as a routine cardiovascular screen.
What to know about Fibrinogen
Understanding Fibrinogen means knowing what it reflects, what tends to move it, and the signs that suggest it’s worth a closer look — so you can bring the right questions to your next appointment.
