Fibrinogen

Coagulation factors are proteins in your blood. They help form blood clots to stop bleeding when you have an injury. These proteins are also called clotting factors. You have several different types of clotting factors that are all important for making blood clots.

A coagulation factor test is used to find out if you have a problem with any of your clotting factors that may cause too little or too much blood clotting.

These labs do not agree: the published adult ranges differ by up to 33%, so the same result can read as normal at one lab and be flagged at another — ARUP 150–430 · Mayo 200–393 mg/dL. Both are real published values, shown as each lab states them.
