Soluble Fibrinogen Receptor (sFGFR) in Serum
This test measures the soluble form of the fibrinogen receptor protein in your blood serum. It helps assess blood clotting and vascular health.

Why This Test Might Be Ordered
Your healthcare provider may recommend this test if you have symptoms or conditions linked to abnormal blood clotting, such as bleeding disorders, vascular diseases, or after trauma/surgery. It could also be part of a broader evaluation for suspected platelet or vascular dysfunction.
What to Expect Before the Test
No special preparation is usually needed. You may fast or avoid certain medications for a few hours beforehand, but always follow your provider’s instructions. Bring any recent medications or supplements to discuss with your doctor.
How the Test Works
A blood sample is drawn from a vein, typically in your arm. The blood is processed to separate serum, which is then analyzed to detect the soluble fibrinogen receptor protein levels using a specialized immunoassay method.
What the Results Mean
Results are compared to a reference range specific to your lab, though exact values aren’t provided here. Elevated levels may suggest increased clotting activity or vascular issues, while lower levels could indicate bleeding tendencies or impaired receptor function.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions
What Does This Test Measure?
Your results may help guide treatment for bleeding disorders (e.g., von Willebrand disease) or vascular conditions (e.g., thrombotic disorders). High levels might prompt monitoring of clotting medications, while low levels could lead to adjustments in anticoagulant therapy or further diagnostic testing.
If you have concerns about your results, discuss them with your healthcare provider. They can explain interpretations, compare them to your medical history, and recommend next steps based on your unique situation.
