Updating the Optimal Range for Fibrinogen

Ongoing research confirms the association between elevated fibrinogen and adverse outcomes, including cardiovascular disease, stroke, and vascular and nonvascular mortality. Fibrinogen is associated with inflammatory disorders and is considered a biomarker of inflammation.

Increasing fibrinogen is also associated with neurological disorders, brain trauma (Petersen 2018), and exposure to pollution. Fortunately, maintaining a blood level of omega-3s above 5.12% significantly reduces the fibrinogen increase observed with pollution exposure (Croft 2018).

We are updating the ODX Optimal Range for fibrinogen to better reflect the current research. Studies indicate that the risk of more severe cardiovascular disease increases as fibrinogen levels increase above 300 mg/dL (8.82 umol/L) (Ang 2017, Danesh 2005, Liu 2020).

The new ODX Optimal Range for fibrinogen is 175 - 300 mg/dL (5.15 - 8.82 umol/L).
